WiFi Relay Board with Solid State Relays

WiFi Relay Board from NCD

Our WiFi Relay Board makes it easy for computers of all types to control relays and monitor analog inputs. WiFi 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 WiFi interface.  NCD ProXR Lite series controllers are 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 WiFi 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 WiFi Relay adds tremendous flexibility for various application requirements

Getting Started with a WiFi Relay Board

Start by downloading Base Station at https://ncd.io/start.  Configure your WiFi Relay Board to connect to you network and run Base Station.  This software tool is designed to teach you the features built into your controller and provide you with example commands. WiFi Relays can use either TCP Sockets or Virtual Serial Ports for communication. Base Station was written for Windows using Visual Studio (source code available) and shows you all the commands you need for controlling relays and monitoring external sensors.

How to Order our WiFi Relays

Start by clicking the “Buy Now” button on the right.  Next, choose how many on-board relays you need (up to 8 in this series).  Select the relay options in the red box for type of solid state relays.  Choose the type of WiFi interface you require and add a power supply if needed.  We have been manufacturing many varieties of Relays Controllers with users all over the world!

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

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

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.

Use the Relay Activator to Configure Analog Inputs for Direct Control of Relays

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.

Base Station Software Controlling NCD Relay Controllers

Base Station Software

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!

LabVIEW Relay Control Support Coming in 2018

We are pleased to announce that official LabVIEW relay control drivers will be supported beginning January of 2018.  This is our first official release of LabVIEW drivers for ProXR series Relay controllers!  We are finalizing the drivers and resources now.  We will post in the News section as well as the Learn section of our site as soon as we are ready.

LabVIEW ProXR Relay Drivers

ProXR Lite vs. ProXR Series

ProXR Lite controllers are smaller, surface-mounted variants of the ProXR Series relay controllers.  The firmware is nearly identical between the series with ProXR Lite being limited to 8 relays.  Only the ProXR series includes a XR expansion port for relay expansion.  ProXR Lite controllers are a lower-cost alternative to ProXR because they are machine manufactured in larger quantities.  ProXR series controllers are currently manufactured with through-hole technology and socketed chips, making them field serviceable.  ProXR Lite controllers are available with little as 1 or 2 relays while ProXR Series focuses on applications that require 4 or more relays.

ProXR Lite Communication Options

We take communications seriously, as we believe in a 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, Ethernet Web-i WebRelay, 802.15.4 Wireless, ZigBee Mesh, Key Fob, 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.

WiFi TCP/IP

Control NCD devices using standard WiFi TCP/IP communications.  Simply open a socket and send and receive TCP/IP data to control our devices.  NCD WiFi communication modules are manufactured by Microchip, the world leader in microcontrollers.

Solid State Relays

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.

WiFi Module Setup

The Wi-Fi Communications Module must be configured in order to connect to your network using the Wi-Fi Configuration Kit. The Wi-Fi Configuration Kit consists of a small black board with 3 LEDs. The Configuration Board will be labeled ZIGMO. The module may have to be removed from the board and plugged into the ZIGMO as shown. The ZIGMO will plug into the USB port of your computer for configuration and some USB drivers may need to be installed on your computer. ...
