This overview shows the hardware features of the ProXR Lite 1-Channel 20A USB relay board, ideal for computer controlled switching applications. This controller has many hardware features, including an extensive relay control command set, including flashers and timers, built-in A/D converters, and the ability to manually control the on-board relay with the ADC inputs. This is the USB version, but users may change the USB interface to other communication technologies, such as RS-232, Bluetooth, WiFi, Ethernet, and industrial wireless. We have a IoT communication module on the way, keeping ProXR controllers at the top of the list for best relay boards in the world.
This ProXR Lite relay controller is capable of switching the on-board 20-Amp SPDT or 30-Amp SPST, ideal for high-power switching applications. The 20-Amp SPDT relay includes 3 quick-connect terminals for normally open, common, and normally closed contact closure relay output connectivity. The 30-Amp SPST relay has two quick-connect terminals for normally open and common connections. This controller features a modular communications interface, capable of accepting USB, RS-232, Ethernet, WiFi, Bluetooth, Industrial Wireless communication modules, and more. On-Board Analog-to-Digital Converters allow monitoring of 8 inputs at 8 or 10-Bit resolution. Analog inputs are ideal for connecting external sensors, or connect buttons and switches to the inputs and configure the controller to manually control relays when buttons are pressed. Turn relays on or off, toggle the state of a relay, or trigger relay flashers all from external switches.
Beginning Late 2020, we’ve made some updates to this product to make it better with increased component count while maintaining the same functionality and footprint. The New Rev G2 Series adds a better power supply circuit to improve noise immunity while providing increased power to the communications socket. We also improved the relay drive circuit to better handle inductive loads. We also changed the color of the circuit board to Black and updated the branding to ncd.io with updated logos.
This is the same product you have been buying for years, but now with improved electronics and while maintaining the same footprint as the original design. Most importantly, this is now a Legacy product, which means it will never go obsolete as long as critical parts are still available to us. Built with our new high-speed pick and place assembly line, we can complete the surface mount assembly process at a rate of several thousand units per day with the potential to scale to any volume you could imagine, so you never need to worry about supply quantities or supply chain problems.
Please note that it was necessary for us to remove the integrated temperature sensor in select versions of this product. This sensor was providing incorrect readings if the relays were active for extended periods of time. We can help you with an off-board sensor if needed.
Base Station Software was designed to help you learn the ProXR command set. Explore ProXR features using our Graphical User Interface.

There is no faster or easier way to learn how to automate than Base Station, as it was designed to work with our complete array of communication modules, including Wireless, Ethernet, USB, RS-232, and many more. You only need a Windows 8 or 10 Computer to Run Base Station. Base Station was written in Visual Studio, and we even provide the source code to help you on your way! Learn More about Base Station Software Here.
This controller is equipped with 8-Channels of 8/10-Bit Analog to Digital Converters, capable of reading analog voltages from 0 to 5 Volts DC. The ADCs on this controller allow monitoring of external sensors or contact closure input detection. Connect external temperature sensors, light sensors, current sensors, buttons, switches, or anything else that generates a 0-5VDC analog or contact closure output. With 8-bit resolution, analog inputs will convert 0-5 Volt signals into a value from 0 to 255. With 10-bit resolution, values of 0 to 1023 may be measured. Input resolution is software selected. Simply ask the controller for the analog value of each input, and the controller instantly responds.
The Relay Activator control panel allows analog inputs to directly control relays. Simply connect the analog inputs to buttons or switches and trigger basic relay on or off functions to take manual control of the on-board relays. The Relay Activator control panel allows you to define 8 functions for each of the 8 inputs. Functions include turning relays on or off, toggling the state of relays, momentarily flash a relay, momentarily toggle the flashing function of a relay, turn all relays on, turn all relays off, and push notification events. When push notification events are configured, the controller generates a packet of data every time the inputs change state.
Base Station helps you learn how to use ProXR Series relay controllers. In this video, we will cover some of the most commonly used features.

Online Manual for ProXR and ProXR Lite Series Controllers
NCD ProXR Series Controllers have been in production for many years and have amassed a large user base since their initial release in the early 2000s. Due to the large client base, we have no plans to discontinue this line of products. In many cases, we are upgrading these devices to make them compatible with automated assembly processes along with improved driver and power electronics capable of supporting many communication technology changes well into the future. Rest assured, ProXR will continue to be a stable part of our product line for many years to come. ProXR series controllers manufactured with a Black circuit board have been migrated to automated assembly and are considered to be the final iteration of this product. These devices can be manufactured in high volumes in a much shorter period of time.
NCD supports integration of NCD relay controllers using LabVIEW. We have included samples and drivers for basic and advanced operation which cover most functions including Relay Timers. We have posted several tutorials on this topic here.
We take communications seriously, as we believe in modular communications and firmware that properly supports scalability into future interface technologies. ProXR controllers support API communications, which effectively wrap every command with a header, payload, and checksum to ensure reliability. NCD API commands increase processing speed because no serial timeout is required prior to command processing. NCD API commands increase reliability, as only a proper checksum will authenticate a command and allow it to process. When we first implemented API, internet communications via a TCP/IP socket could be realized because the timing problems of internet communications were eliminated. While API is optional, it is strongly advised. Our Base Station software uses API communications, so it’s possible to control a ProXR controller over the internet after configuring port forwarding on your router.
ProXR series controllers are the world’s most adaptable controllers, capable of communicating with a wide variety of communication options. Pick any of your favorite communication technologies: Bluetooth, USB, WiFi, Ethernet, Key Fob, RS-485 or RS-232. ProXR easily adapts to the communication technologies you need most. We are committed to modular communications, so your ProXR series controllers can easily be retrofitted for other applications as your needs change. ProXR controllers are never obsolete, as we are actively releasing new communication technologies that greatly enhance the connectivity of our ProXR series controllers.

Long-Range Wireless Mesh networking is our favorite of all wireless communication technologies. This 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 not hop between sleeping sensors. Data will hop from sensors to gateways and modems. Data will also hop between gateways and modems. Learn more about our long range wireless module here.

Analog Inputs should not have a voltage present when powered down. Use a 220 Ohm current limiting resistor on each input to prevent damage to the controller if voltage will be present on the analog input when this controller is powered down. Do not exceed 0 to 5VDC on any analog input or the on-board CPU will be damaged. Most analog inputs include a 10K Pull Up/Down resistor to help keep the inputs quiet when not in use. This 10K resistor may slightly bias the readings of some sensors.
