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.
Simple Setup
- Connect your device's contact closure output to the Sender Board
- Wire the Receiver Board relay to your equipment at the remote location
- Activate the closure → remote relay responds almost instantly
Choose Your Communication Interface
How should the boards talk to each other? Select the interface that fits your installation:- Each section below shows the 4-Channel MirC options available
- Interfaces define how the pair communicates (wireless, networked, wired)
- Boards are a married pair - they only talk to each other, even if other MirC systems are nearby
