Our Ethernet Relay boards makes it easy for computers of all types to control relays and monitor analog inputs. Ethernet Relays allow you turn relays on or off, flash relays continuously, control relays for a duration of time, and control relays in groups using a cross-platform compatible Ethernet interface. This Ethernet Relay is a ProXR Lite series controller which is a widely adopted standard used by industry for many years. Equipped with your choice of 1, 2, 4, or 8 on-board relays, the ProXR Lite series Ethernet Relays suit the needs of most of our customers. Integrated Analog to Digital Converters may be used to manually control the relays, or they may be used to read external sensors. Equipped with 8 or 10-Bit resolution, the ADC built into each Ethernet Relay board adds tremendous flexibility for various application requirements.Ethernet relays support DHCP or a Static IP address with a programmable port number, 2101 is used by default. NCD Ethernet communications module will transmit the IP address of the device using periodic UDP broadcasts, which make it easy to locate the device on a network.
Start by downloading Base Station at https://ncd.io/start and Run the application. A window will appear which listens for all NCD UDP broadcasts. Plug in your Ethernet Relay Board and wait for the Network window to populate with the IP address of the Ethernet Relay Board. Simply click the IP address of the device and “OK” to establish a connection.Base Station is a tool designed to teach you all the features built into your controller and provide you with example commands. Base Station was written for Windows using Visual Studio (source code available on the download page linked above). Base Station shows you all the commands you need for controlling relays and monitoring external sensors.
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. 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 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!

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.
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.
Control NCD devices using standard Ethernet TCP/IP communications. Simply open a socket and send and receive TCP/IP data to control our devices. Our Ethernet TCP/IP Communication modules feature our 3rd Generation Ethernet to Serial communications module. Use the integrated web page to configure settings. Upload your own customized web page to add special features to this device. We have included a few sample HTML files to help you get started.

Solid state relays are ideal for agricultural switching applications, or remotely located switching. SSRs are frequently chosen to control pumps, valves, solenoids, lights, and other high-reliability applications. NCD solid-state relay controllers do not include solid-state relays, but you will have the option to choose the type of solid state relays you require when customizing your product. This controller is designed specifically to fit select Crydom solid-state relays, but may be compatible other solid-state relays made by other companies. Review Solid-State Relay Options
