Our Bluetooth ProXR Series Relay Controllers make it easier than ever to add Bluetooth wireless switching to your most demanding computer or smart phone control applications. Simply pair to your smart phone or computer this controller. The controller mounts as a Virtual COM Port on your PC, allowing easy programming from any language that supports serial communications.
Smart Phone & Computer Pairing
This Bluetooth Relay will be paired with a Bluetooth connection on your smart phone or computer. This involves opening the Bluetooth control panel on your computer, pressing the "pairing" button on our controller, and finally, using the Bluetooth control panel to add the device to the Bluetooth network. Once paired, the NCD part number will appear in your Bluetooth control panel, and a new COM port will be available for use on your computer. To communicate to the device, all you have to do is open the new Bluetooth COM port at 115.2K baud and start sending commands. The Blue LED on our controller will light as soon as the port is opened.
This board is equipped with a ZBT Module. The ZBT communications module adds Bluetooth communications to the board. The ZBT module is powered from the board. The board itself will require 12 volts of power and can be hard wired or you can purchase a "wall wart" type Power Supply
at checkout. Bluetooth Module Options
Configuration is easy with the optional Bluetooth ZigMo Modem. Simply connect it to the USB port of your computer with the supplied cable and you will be able to select a COM port, change the baud rate or enter a security pin code. The Bluetooth ZigMo is available as an option when you purchase your Bluetooth controller. The ZBT module will pull off the board and can be installed in the ZigMo for configuration. You can then configure the baud rate and password settings if you require a secure wireless control. After configuration the ZBT module can be reinstalled in your board and it will be configured to fit your needs. For more information on Bluetooth configuration see Configuring the Bluetooth Module
Base 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.
Android App Available
The app can be downloaded from the Google Play marketplace
. Currently it allows you to control up to 8 relays each with individual names. All you have to do is download the app, pair with the desired Bluetooth Board, open the app and select the desired device. Select how many relays your board has, name them if desired.

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 controller 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. In the case of Ethernet devices, customers may experience loss of communications until the device is reconnected. Capacitors that we offer are available at checkout, for more information view our Induction Suppression Video
SPDT Relay Controller
This device has SPDT relays installed. SPDT Single Pole Double Throw Relays have three connections - Common, Normally Open, and Normally Closed. When the relay is off, the common is connected to the normally closed connection of the relay. When the relay coil is energized, the Common swings over to the Normally Open Connection of the Relay. You can wire the device you are switching to either the Normally Open or the Normally Closed position. For more information on selecting the correct relay amperage for your application see Choosing a Proper Amperage
Easy Software Development
Most of our customers write their own program for controlling these devices and use almost any language to do this. This boards supports the Serial Port Profile, meaning they will mount to the computer as a virtual com port making it very easy to send commands to the device. This board will support almost any programming language you are comfortable with.

ProXR Lite Relay
We've looked at the interface and the programming now let's take a look at the board design itself. The ProXR Lite series controllers are machine manufactured for a highly accurate and reliable design. Fully tested before they leave the production facility each ProXR Lite 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!
Break-A-Way Tabs for a Smaller Design
The ProXR Lite relays have a great feature where space is a premium - Break-A-Way Tabs. The Break-A-Way Tabs allow most boards to fit in an optional undrilled plastic enclosure. Snap off the Break-A-Way Tabs and you have a controller with a smaller profile when you need to fit in a tight space.
Unlike it's big brother, the ProXR Series, the ProXR Lite series controllers are NOT expandable. The firmware still thinks 256 relays are available but the relay portion of the controller only responds to the first 1, 2, 4 or 8 relays in Bank 1.
Read Analog Sensors
We did NOT skip the Analog Input portion of the ProXR Lite. All ProXR Lite controllers offer 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! Look for more on this below.
Full ProXR Enhanced Firmware Installed

Analog to Digital Conversion
Analog Inputs are very special in that they are sensitive to voltage changes. Analog to Digital (A/D) conversion is the process of converting a voltage in the range of 0 to 5VDC into a number that can be processed by custom software that you develop. The ProXR Command Set
will allow you to send a command to the board and read voltage levels from 0-5 volts using 8-bit resolution. 8-Bit resolution will read the voltage input (from 0 to 5VDC) and then is interpreted as a value from 0 to 255. Zero being a contact closure input.
- A voltage input of 0 Volts is interpreted as a value of 0
- A voltage input of 2.5 Volts is interpreted as a value of 127
- A voltage input of 5 Volts is interpreted as a value of 255
So if you divide 5 Volts by 255 possible steps (0-255 for 8-Bit resolution), the board is sensitive to voltage changes as small as 0.019 Volts. This controller has eight A/D inputs, each input is capable of reading a separate voltage from 0 to 5 VDC, provided all voltages can share a common ground. This is particularly useful for reading temperature sensors (one temperature sensor is built into select boards mostly 4 & 8 channel, shared with analog input number 8). A/D Inputs are also useful for reading light level sensors, thermocouples, switch closures, or just about any other kind of sensor you can think of.
A/D Sample Programs Available
Eight Different A/D Sample programs are available in the
. These samples are available as a free download and are compatible with Visual Studio.
N-Button creates widgets or buttons to control up to eight relays without any programming. A new button will be created and placed on the desktop of your computer for each relay that you want to control. N-Button supports Serial Port/ USB and Network connection between PC and relay board. N-Button Manager makes it easy to add any type of button to the desktop and change the properties.
Analog to Digital meters can also be added to your desktop to instantly read the status of any sensor or probe you may have connected to the board. Each meter is customizable and can be changed without any programming knowledge.
Relay Button widgets turn on/off relay directly. It has never been so easy to control relays before.
Relay Status widgets show status of the relay automatically.
A/D Meter widgets display the value of A/D channel automatically.
Customized Button widgets can send user-defined data to relay board. It also supports to open or run other file and application.
N-Button Lite version supports up to 8 widgets. If you want to add more than 8 widgets, you need upgrade to the standard version.
Attention: 0 to 5 Volt Input
Please Note: Users must ONLY apply a voltage between 0 and 5 volts to the A/D input on this controller, higher voltages will damage the controller.
Attention: Relays Provide No Voltage Output
Please Note: Relays do NOT provide a voltage output. They provide a contact closure output, exactly like the terminals found on a light switch at your local hardware store. Wiring to a relay will be slightly different depending on the model controller you choose.
For wiring information see our Relay Logic page.
