900 MHz Relay 4-Channel 1-Amp DPDT with UXP PortZUXPR41DPDTPROXR_XSC
900 MHz RelayThe ZADSR41DPDTProXR_XSC 900 MHz Relay will allow you to wirelessly control the relays using a 900 MHz frequency band. The board uses a modem connected to the USB port of your computer to wirelessly communicate to the board. The modem mounts as a COM port on your PC, send your commands to the COM port and the modem wirelessly sends the command to the board. That's all there is to it!!!
ZADSR41DPDTProXR_XSC The Ideal ChoiceThe ZADSR41DPDTProXR_XSC 900 MHz Relay is an ideal choice for applications that require fast, reliable wireless relay control using a computer. The 900 MHz frequency allows for better communication through walls and obstructions. While line-of-site is always vital for optimal range the 900MHz frequency is the best option when obstructions are unavoidable.
900 MHz Relay - ProXRThis is a ProXR board meaning that it has the industry leading command set and the board can be expanded to include up to 256 relays. Adding relays is as easy as adding expansion boards as your needs arise.

900 MHz boards operate reliably and efficiently when the antennas can “see“ each other. Obstructions like walls, buildings and even trees and hills can diminish the signal or prevent communication altogether. Metal being the worst for any wireless signal to penetrate with stone and brick and being a close second. Positioning the antennas for line-of-site operation will greatly increase reliability.
Wireless Relay Control
Long Range Wireless Industrial MeshLong-Range Wireless Mesh networking is the ONLY communications technology NCD recommends on the factory floor, operating at a safe 900MHz. Mesh technology will hop data from one location to another to reach its intended destination, users do not need to do anything other than make sure wireless modules stay within hopping range of each other. We use the Digi 900HP-S3B module in many of our products, as this is the best industry has to offer. With a 2 mile range between modules and up to 8 hops, it is possible to cover 16 miles of wireless territory using this technology. Using high-gain antennas, this module is capable of communicating to a remote module up to 28 miles away! Please note that data hopping only works between live devices. Data will hop from sensors to gateways and modems. Data will also hop between gateways and modems.
Long Range WirelessXBee-PRO 900HP embedded modules provide best-in-class range wireless connectivity to devices. They are easy to setup and use, reliable and capable of transmitting a ling distance. You will need an 900MHz modem that plugs into your USB port of your computer to talk any number of boards with a standard range of 2-miles and up to 15 miles. You can choose the distance of the module installed at checkout.
XBee-PRO 900 RF ModuleThis board is equipped with an 900HP Module. The XBee-PRO 900 RF module is ideally suited for less power-hungry, low-latency point-to-multipoint networking applications. Capable of point-to-point, peer-to-peer and point-to-multipoint networking, The XBee-900 modules have a higher selectable transmitting power of 250mW. This higher TX power allows for line-of-sight range up to 28 miles with the right antenna. It is ideal for solutions where RF penetration and absolute transmission distance are paramount to the application.
Line-Of-Site OperationAs with any wireless technologies, for optimal performance it needs to be line-of-sight. In other words the antennas of the board and modem must "see" each other to get the optimal range or even be able to communicate at all. Mounting slots on the modem make it easy to attach to a wall to allow for line-of-site operation.
Standard Range AntennaThe XSC900SR Standard Range Antenna (distance of 2 miles) is included with the price of the controller. The included antenna is a 6" whip antenna with an RP-SMA threaded connection. The antenna will screw directly onto the wireless module. NCD has tested this device at 2 Miles with excellent results using smaller antennas than what would be required to achieve the 28-Mile range achieved by the manufacturer. All range tests are conducted in clear line-of-sight installations. It is not possible for us to accurately predict range prior to purchase. We cannot predict range inside buildings, using google map images, or predict interference that may be present at your location that would prohibit proper operation.
900MHz Wireless ModemPlug the UXSCMSR_ZIGMO short range modem or UXSCMLR_ZIGMO long range modem into the USB Port of your computer. The modem will mount as a COM port on your PC. Open the COM port and start sending data to the modem. The modem will forward your data to all Wireless XSC compliant devices within range (it is also possible to speak to a specific device when other controllers are in range). The modem is also available at checkout.
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 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.

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. These boards support the Serial Port Profile, meaning they will mount to the computer as a virtual com port. This makes it very easy to send commands to the device.
Plug-In for Visual StudioThe NCD Component Library is a plug-in for the Visual Studio 2005/2008 that greatly simplifies the communications to the NCD product line. The samples can be run in Visual Studio and full customization to your needs. Over 40 samples included with this free download! Component Library.
Base Station SoftwareBase Station Software was designed to help you learn the ProXR command set. Explore ProXR features using it's Graphical User Interface. Watch data bytes flow to and from the board, so you easily understand the command execution process. There is no faster or easier way to learn how to automate than Base Station, as it was designed to work with the complete array of communication modules. Base Station software supports every feature of this device - no other controller manufacturer even comes close to offering this type of software.
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.

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.

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.
