One-Way Control, Simplified

MirC is available in 1, 2, 4, or 8-channel models.
Each system includes a dedicated Sender Board with dry contact inputs and a Receiver Board with matching relay outputs.

Inputs on the Sender Board control the relays on the Receiver Board - providing reliable, one-way control to a remote location.

Looking to control a relay from a different location? These MirC sets offer reliable, contact closure relay control for switching...almost anything!

Contact Closure Relay Control

MirC controllers let you send dry contact (no voltage) signals from one location to another - without running wires. Each system includes two boards:
  • Sender Board - accepts contact closure inputs
  • Receiver Board - activates relays at the remote site

How It Works

Use the receiver relay to switch power to your device, or as a dry contact output. Perfect for applications where a contact closure needs to be extended across long distances.
