Ethernet Relays from NCD

Our Ethernet Relay boards make it easy for computers of all types to control relays and monitor analog inputs. Ethernet Relays allow you to 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.

Getting Started with NCD Ethernet Relay

Start by downloading Base Station at and Run the application.  A window will appear which listens for all NCD UDP broadcasts.  Plugin 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.
