The Ideal Wired Choice
When wireless isn't allowed and network infrastructure isn't available, the MIRCR110_ZRS gives you dependable point-to-point control using just three wires. With a range of up to 1000 feet, it's a straightforward, reliable wired solution.
Wired Contact Closure
The sender accepts contact closure (no voltage) inputs, which instantly control the relays on the receiver board providing seamless, wireless communication between two points. Each purchase includes a complete MirC pair (both boards), ready to install.Contact Closure Input & Output
The relay on the receiver board can be used to either switch power to a device or act as a dry contact closure. This allows the MirC system to extend contact closure signals over long distances. Connect your device's contact closure (no voltage) to the Sender Board, and the Receiver Board will recreate that contact closure at the remote location.Choosing the Right Relay Amperage
The 2-Channel MirC boards include two dry contact inputs on the Sender Board and two relay outputs on the Receiver Board. The key difference between the options is the amperage rating of the relay installed. Select a board that matches the amperage required for your application.- SPDT relays are available in 5-Amp, 10-Amp, and 20-Amp versions.
- An SPST relay is available in a 30-Amp version.
💡 Relay Pros ProTip:
If you're controlling high-current loads like motors or heaters, always choose a relay with extra amperage headroom. Running a relay at its maximum rating can shorten its lifespan.
