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 2-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
