Ethernet Relay Board with Solid State Relays

introduction

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.

how to use

Getting Started with NCD Ethernet Relay

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.

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!

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.

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.
