Web Relay Controller Boards from NCD

Our Web Relay Boards make it easy for you to control relays and monitor inputs using any web browser or software. A Web Relay Board allows you turn relays on or off, create macros to send multiple commands, monitor inputs, and write your own software to do any of these things and more with your own software. This Web Relay Controller 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 Web Relay Controllers 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 Web Relay Controllers add tremendous flexibility for various application requirements.Web Relays 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.

Getting Started with NCD Web Relay Controller Boards

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 Web Relay Board and wait for the Network window to populate with the IP address of the Web Relay Board. Enter the IP Address into a Web Browser or double click on the Web Relay Board in Base Station you should be brought to the Web Page for that board. From there you can configure the interface, control relays, or read inputs.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.
 

New Version Now Shipping

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.

AD8 8-Channel 8/10-Bit Analog to Digital Converters

ProXR ADC
ProXR Analog to Digital Inputs are used to Read External Sensors or Manually Control On-Board Relays
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.

Relay Activator and Analog Inputs

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.

ProXR Quick Start Guide

Online Manual for ProXR and ProXR Lite Series Controllers

Good to Know!

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.

ProXR Lite Communication Options

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.
