Interfaces are not included with this board. An interface is how you will communicate to the board. This board is controlled by sending commands to the board through a computer. Without one of the interfaces below there will be no way to communicate to the board. Below are the interface options available.
Refurbished boards have the most current firmware and face the same strict testing procedures that all our boards undergo. This B-Stock or Refurbished board is a fully working board that may have slight scratches or blemishes that do not effect the operation of the board. The board may be an overstock or returned from a customer.
This board may not have a communication Interface installed and you have the ability to select the interface you would like at checkout. The interface must be selected of you will not be able to communicate to the board.
There are most likely limited quantities of this board available. We do offer quantity pricing on our boards and can offer this if there is sufficient quantities available.
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!
The ProXR DPDT Relay Board
Easy Software Development
Most 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 Studio
The 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 Software
Base 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.
Essential Power Requirements
Applying 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.

Read Analog Sensors
This ProXR controller offers a 8-Channel 8/10-Bit Analog to Digital Converter in addition to relay control. Read and control from 8 sensors per board from 0 to 5 volts!
ProXR Enhanced Firmware Installed
This 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.
DPDT Relays Installed
This 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.
ProXR 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 Compliant
This 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 Grow
The 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 Timers
The 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 Guarantee
ProXR 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.
Perhaps 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.
The boards sold are brand new units shipped from our office conveniently located in Missouri. These boards are completely tested before they are released for shipping With so many boards on our site it is impossible to stock boards, please allow two to three days production time for your order to ship.

The PWR12 is regulated power supply providing clean power necessary for
the performance of these boards. 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 R/A barrel connector.
an inductive load using our relay controllers requires the use of induction suppression capacitors. 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 electrically interferes with the microprocessor
logic of our controllers, causing relay banks to shut themselves down unexpectedly.
Lite is software that allows you to configure buttons to control relays and read the status of those relays without programming. You
can also create meters for reading variable input sensors connected to the board in real time!
