XR Expansion Relay Banks

XR Relay Expansion Controllers add a large variety of relay switching capabilities to an existing NCD device!

XR Expansion Ports are used to add banks of external relays to an NCD device.  As we continue to develop new devices, a modular architecture will be implemented, offering the greatest amount of user flexibility.  Separating the brawn from the brains allows us to continue to develop more intelligent controllers without making existing hardware obsolete.

Our Line of XR Expansion Relay Controllers add unlimited computer controlled switching potential, using a simple, modular upgrade path.  From low power signal switching to high current, high voltage control, we offer an XR Expansion controller that will meet your switching requirements.  Available with Single Pole Double Throw (SPDT) and Double Pole Double Throw (DPDT) relays, Open Collector Outputs (OC), and 8, 16, 24, or 32 outputs per expansion board.
