Gen3 Ethernet Relay
Ethernet Relay ControlIntroducing the NCD5500 Ethernet to Serial Converter. NCD's 3rd Generation Converter setting new standards for reliability, low-cost, and ease of use! Connect the complete line of NCD Industrial Devices to your Ethernet Network using this modular communications module from NCD. Based on the their next generation Ethernet to Serial Converter, the NCD5500 was customized specifically for use with NCD devices to ensure optimal compatibility with our complete line of products. This Ethernet communications module essentially converts TCP/IP data into serial data bytes, and sends these bytes to the complete line of NCD devices via Serial Communications. This Ethernet communications module is suitable for use with endNode, ProXR*, ProXR Lite*, Fusion, Reactor*, and Taralist* series controllers as well as a broad range of IoT connected devices. This Ethernet to Serial Communication Module is also Compatible with Alpha Station and Base Station, Making it Easy to Discover the IP Address. Please note the Default Web Page Login Password is admin and may be changed by the user.
Ethernet to Serial Communications ModuleThis Ethernet to Serial Communications Module converts TCP packets to Serial data and vise versa. This device can be configured to automatically close the socket after a programmable timeout or to leave the socket open. A blue LED light indicates an open socket connection. Program the Baud Rate of this Device from 9600 to 115.2K Baud and communicate to this device over the default TCP port 2101. This device also supports Static IP Addresses, DHCP, and has the ability to recover back to factory default settings with a simple press of a button!
DHCP and Static IP AddressesThis module supports both DHCP and static IP Addressing. For communications reliability, especially via Remote Access, we recommend using a Static IP Address when you feel comfortable doing so. This will ensure that the device will always be where you expect it to be when you try to connect to it.
TCP/IP CommunicationsThe main method of communication to the Ethernet modules is a standard TCP Socket. This communication protocol makes use of Network Sockets to create point to point tunnels that data can flow through bi-directionally. In this way the computer that is controlling the relay can send commands and shortly thereafter receive the response through the same Socket.
3rd Generation Hardware Now ShippingThis is NCD's 3rd generation hardware for Ethernet to Serial communications, representing giant steps forward in reliability, easy of use, recover-ability, and LOW COST. Yes, we are actually LOWERING the price of this device as costs have shrunk considerably from previous generation Ethernet to Serial conversion technologies. Other significant improvements include new recovery options. Not only is a web UI supported (as in previous generations), but also a new Windows application may be used to change settings and recover modules with an unknown IP address! New firmware upgrade options are now available, allowing users to upgrade firmware as new features are released.
Password ProtectionThe Gen3 Module has security built-in. Under the management tab users have the ability to assign a password to the module for security.
Port ForwardingWhen using this board over the internet and outside the Local Area Network, Port Forwarding will be required. Port Forwarding is a protocol used by your router to allow incoming requests for connections to get through to a specific device on a specific port. Below is an example of how it works. In this example a router has been setup to forward incoming requests for port 2101 to the device at the IP Address 192.168.2.19 on port 2101. Now when any device that tries to access this Port on the External IP Address the router will see the request and automatically forward the request to the device at the IP Address of 192.168.2.19 on port 2101. If this Port Forwarding rule was not in place and a request came in on port 2101 the router would not know which port or device to forward it to and the request for connection would be denied. Note: Port Forwarding will not be necessary when using this within a Local Area Network. For more on Port Forwarding with detailed instructions for every router visit: https://portforward.com/ .
Sending CommandsBase Station Software is available at no charge to get you up and running fast (more on Base Station below). Once powered up, the controller waits for a ProXR command. A command consists of a few bytes of data in numerical format (ProXR Enhanced Command Set) usually between 2 and 6 bytes. Once the command has been received, the controller processes the command, and sends you back ASCII character code 85 to signal the completion of your command. If a command was sent to read the status of the relay the status is sent back.
Control relays from any device with a browser using the IP address of the board! The Gen3 Module can be configured to upload HTML pages that can be accessed by your smart phone, tablet or computer.
Gen3 Web Page Control
3rd Generation EthernetOnce seperate modules the Gen3 Module have the added capability to configure the module for use with a browser. The New Gen3 Ethernet module has the ability to store web pages that can be used to control the relays! The web pages are already created and can be uploaded to the modules through the free configuration software. You can upload the already existing working pages ready to use or you can modify them in your favorite HTML editor and upload the custom pages. There are pages created for the specific number of relays installed on the board you are using.
Connectivity OptionsOnce configured the web pages can be accessed remotely through an Internet connection using any device with an embedded web browser such as a smartphone, tablet, or computer. Since it is browser based you can use any operating system from Andriod, iOS, Windows and any browser!
Working Web PagesThe Gen3 Module has working web pages for the specific amount of relays tha tyou have on the board. there is also a page for reading the analog inputs on the ProXR Lite boards. You can also set passwords and create macros all through the IP address of the controller.
Read Analog SensorsAll ProXR Lite controllers offer a 8-Channel 8/10-Bit Analog to Digital Converter! The ADC page was creatred to read the variable resistance AD inputs and will then will return a value between 0-255. Meters on the page and will display the value of the inputs for a live look at the inputs right on your phone, tablet or computer!
Smart Phone ControlOnce the Web-i web page appears on your smart phone, bookmark the page so you can access your relays just like an App on your home screen of your smart phone. Using this method, you can be anywhere in the world and still monitor and control relays as long as your mobile device has an internet connection. It even works using 3G and 4G internet services, so you can be in your car and stay in control of your relays.
LAN or Internet ControlControl relays from your local internet only when you are connected to your local area network or control from the internet from anywhere outside your network. Once your router is properly configured for port forwarding, users may access the web pages built into the Web-i interface from anywhere in the world just like it were a normal web site. Simply use the Web-i web pages to monitor and control your electronics or customize the pages for your own needs.
Web-i SetupThere is a bit of configuration that will need to be done in the module in order to upload and use the web pages. In the configuration software you will select the Web-i option. Once selected you will have the ability to upload the web pages to the module through the same software. You will upload HTML pages with controls that match the number of relays on your board. We reccommend setting a static IP address which will be used in your browser to access the web pages.
ProXR Expandable Board
This Board includes the XR Expansion Port for adding additional relays to the board. The XR Expansion Boards can be added to control up to 256 relays on this board!
ProXR RelayWe've looked at the interface now let's take a look at the board design and programming. The ProXR series controllers are manufactured by hand for a highly accurate and reliable design. Equipped with the XR Expansion Port additional relays can be easily added. Fully tested before they leave the production facility each ProXR controller is ready to stand up to rigorous demands from heat, cold or vibration. The best test of all is the numerous boards in the field from customers all over the world in all sorts of conditions. Take it from us, these controllers will hold up!
Easy Software DevelopmentMost of our customers write their own program for controlling these devices. Since you can use almost any programming language, you can use one that is most familiar to you so you don't have to learn a new language.

UXP ExpansionUXP is a new standardized data port, specifically for the purpose of speaking to various expansion modules. If the controller you are considering is equipped with a UXP port, you can take advantage of extended commands to speak to our growing line of I/O expansion modules. You will find the UXP port on models with UXP in the part number.
- Summary of UXP Modules
- Compatible with UXP Series Controllers ONLY
- Not a stand-alone controller - MUST be used with a UXP Series Controller
- Add Contact Closure Inputs
- up to 256 Inputs
- Add Analog to Digital Inputs
- up to 48 Inputs

UXP Expansion ModulesUXP Expansion Boards have no on-board brains. They are entirely reliant on the brains of a "master" device. A master device is an NCD controller with a UXP expansion port and a microprocessor of some kind. Most master UXP devices have on-board relays. If you need to add A/D, Contact Closure Inputs or Digital Potentiometers just plug in the appropriate expansion module. You cannot daisy chain different types of modules to the same controller however. In other words if you plug in a potentiometer you will not be able to plug a contact closure or A/D module also. For controllers that are equipped with a UXP Expansion port (and are suitable master devices for UXP Series Expansion) simply look for UXP in the part number. All UXP Expansion Modules have an input and an output so you can simply daisy chain the boards together until you reach the number of contacts you are looking for.
XR Expansion PortMost UXP controllers (Master Devices) have an XR expansion port and therefore can accommodate XR Expansion Boards. Typically the XR Expansion port is used to add relays to the main controller (Master Device). Like the UXP Expansion boards the XR Expansion Boards have no on-board brains. They are entirely reliant on the brains of a "master" device. When you run out of relays, just plug in an XR expansion board that is equipped with the kind of relays you need. You can add up to 256 relays including the relays that are on the main controller (Master Device). All XR Expansion modules are compatible with each other so if you want to add different types of relays you can. For controllers that are equipped with an XR Expansion port (and are suitable master devices for XR Series Expansion Controllers) simply look for PROXR in the part number.
Using XR and UXP TogetherIf you select a board that is equipped with both XR and UXP port you can use both ports simultaneously. This allows you to add and control more relays through the XR port plus add A/D, Contact Closures or Potentiometers to the same board through the UXP port. This can all be controlled through the same virtual COM port on your computer. These Expansion Boards can be purchase with the controller or purchased at a later time when you have a need to expand. To use both ports together you will need to select a controller that has UXP and PROXR in the part number to have bothports available on the controller (Master Device).
ProXR Enhanced Firmware InstalledThis board has ProXR Firmware installed that responds to the full ProXR Command Set. The ProXR Firmware is the industry leading firmware for controlling relays with more commands and functionality than any other board on the market. The list of commands and parameters this board is capable of is extensive. ProXR Enhanced is the newly released enhance version of the ProXR Firmware with more commands, more functionality and better control than ever before! For a detailed list of all the commands with descriptions see our ProXR Enhanced Command Set.
Essential Power RequirementsApplying Good clean power to the board is essential for the operation of the board. Not only for the switching of the relays but the firmware that processes the commands. Without good steady clean power from a regulated power supply the board simply will not function correctly. All boards on the site require 12 VDC power. The PWR12 US power supply is a 120VAC to 12VDC 1.25A 60Hz regulated power supply and it plugs into the barrel connector on the board. The output connector is a 2.1mm I.D. x 5.5mm O.D. x 9.5mm Female R/A barrel connector. We also carry an international power supply with interchangeable adapters for international customers. Learn More
DPDT Relays InstalledThis board has DPDT relays installed. A single DPDT relay is made up of 2 SPDT switches. Each relay acts as two switches that are activated at the same time. This allows two independent signals to be switched at one time. In effect, there are two independent switches on a single DPDT relay - they will always switch together.
There are two connectors with Normally Open, Normally Closed and Common for each relay allowing two separate connections. The picture above shows the 4-channel connectors. The diagram to the right shows the how the arms of the common connector swing from the Normally Closed to the Normally Open positions when energized. Wiring to either the NO or NC can produce your desired results.
2-Million CyclesProXR series controllers are designed for long life, you should expect to get years of service from your controller and literally 2-million cycles from the relays on board. With a 5-year warranty and a money back guarantee you have nothing to loose! Place your order now, while everything is in front of you.
This Board is RoHS CompliantThis board is led free and RoHS Compliant. If your requirements are for RoHS compliant parts this board is manufactured with RoHS compliant led free parts and solder.
Add Relays as Your Needs GrowThe ProXR series controllers are expandable up to 256 total relays. The controller is fitted with an XR Expansion Port where you can add expansion boards to this relay. Expansion boards can be added until you reach 256 total relays. The Expansion Boards get their logic from the main board and will require 12 VDC power. Expansion boards do not need to be the same relay amperage as the main board or other expansion boards.
16 User-Programmable TimersThe ProXR Series controllers have 16 user-programmable timers. Each independent timer can be assigned to any relay, and can be programmed to hold the relay in the On state, or to pulse the relay at the end of the timer. The ProXR timing features are ideally suited for Watchdog, Keep Alive, and Server Reboot applications, as well as sprinkler systems, gate openers, and lighting applications. Relay Timing Features support two modes of operation: Duration and Pulse. Duration timing is ideally suited where a device should be activated for a period of time. Pulse timing mode is designed specifically for server reboot applications, whereby, if the timer is not reset periodically by your software, the timer will run out and reboot your computer.
5-Year Warranty/Money Back GuaranteeProXR Lite series controllers are guaranteed against manufacturing and functionality defects for a full 5 years! Not to mention a 30-day money back guarantee! If for any reason you are not happy with a relay purchased from Relay Pros, simply return it within 30 days and we will give you your money back! Controllers that are damaged by our customers will not of course be warranted under any circumstances.
Induction SuppressionPerhaps the most overlooked aspect of relay control is proper handling of inductive loads. Inductive loads can best be defined as anything with a magnetic coil, such as a motor, solenoid, or a transformer. Controlling a inductive load using this relay board requires an induction suppression capacitor for each relay being used. The purpose of this capacitor is to absorb the high voltages generated by inductive loads, blocking them from the contacts of the relay. Without this capacitor, the lifespan of the relay will be greatly reduced. Induction can be so severe that it interferes with the logic of the board, causing relay banks to shut down unexpectedly. For more information view our Induction Suppression Video.
