Solid State Ethernet Relay

Solid State Network Relay

Computer Controlled Switching from
Anywhere on the Network

Unmatched Solid State Reliability and Induction Tolerance!  Data Collection and Control with Future Expandability in Mind.  These ProXR Series Solid State Ethernet Controllers are Feature Rich and Ready to Grow with your Needs! The Solid State Ethernet Relay Board Connects to the Ethernet Port of your Local Network Hub, Allowing Computer Controlled Switching from Anywhere on the Network.  Current Solid State Ethernet Controllers offer Relay Control + 8-Channels 8/10-Bit A/D, or Relay Control + UXP Expansion Port.  All versions include an XR Expansion Port for adding additional relay banks.  Using our Standardized ProXR Command Set.

    Summary of Ethernet Communications
  • Ethernet Interface Mounts as a COM Port on your PC Through your LAN
  • Supports Telnet and Data Encryption with password protection
  • Embedded Digi Connect Wi-MEĀ® Ethernet Interface and Web Server from
  • Plug in, open the COM port and start sending commands
  • SPDT, DPDT and Solid State versions
  • Control one relay at a time or all relays at once with manual and automatic refreshing command set
  • ProXR versions are capable of controlling up to 256 relays
  • CPU status LEDs show command processing Activity

The ease of setup and expansion of our
4 Channel Solid State Ethernet Relay Board is demonstrated above.

4 Channel Solid State Ethernet Relay Board

Solid State Ethernet Relay

Our Solid State Ethernet Relays feature four and eight channels with your choice of relays (see below).  You can even customize each relay on the controller!   Solid State controllers are available with your choice of eight channel 8/10-Bit Analog to Digital Conversion or UXP Expansion Port on selected models and all are of course SignalSwitch compatible.  All Solid State Ethernet Boards feature the ProXR Command Set and an XR Expansion Port.  Built from the ground up with expansion in mind, simply chain the XR Expansion Modules to the XR Expansion port, one after another, to meet your computer controlled switching requirements to add up to 256 relays.  For more detailed information, videos, manuals and to order, please click on the links below.

Easy Software Development

Communications and software development is very easy, simply write your software to speak to the RS-232 serial port (COM port of your PC), and install the included RealPort Drivers that allow you to map a COM port to an I.P. address. So you do not have to know anything about Ethernet communications to speak to the device.

Many Communication Protocols for Advanced Users

Advanced users may want to employ other communication protocols to speak the the Ethernet Relay Controller. NCD Ethernet Relay Controllers can also be controlled using Telnet. I.P. Addresses and are automatically or manually assigned. NCD Ethernet Relay Controllers also support security protocols such as Shared Key, WEP, WPA, and Cisco LEAP with support for WEP, TKIP, and CCMP data encryption.

Onboard analog to digital conversion is available on selected models of these controllers! This will allow you to:

  • Read light and temperature levels
  • Easily activate relays when A/D limits are reached
  • Detect audio levels in a room when connected to a microphone
  • Read switches, potentiometers, and analog joysticks
  • applications are limitless, and surprisingly easy to integrate
  • Available on the 4, 8, and 16 channel boards

UXP is a new standardized data port, specifically for the purpose of speaking to various expansion modules. If the controller you are considering is equipped with a UXP port, you can take advantage of extended commands to speak to our growing line of I/O expansion modules. UXP in the part number allows you to:

  • Add Contact Closure Inputs
  • Add Analog to Digital Inputs
  • Add Voltage Detectors
  • Digital Potentiometer Outputs
  • Available on the 4 and 8 channel boards

Models with the ProXR suffix will feature the ProXR commend set. The ProXR series will allow you to:
