One-Way Control

MirC Contact Closure Over IP

Control relays remotely over your local network with MirC MCNET boards. Each pair includes a Sender Board and Receiver Board. The sender accepts dry contact inputs which activate matching relays at the remote location. Perfect for simple one-way control between two points.

💡 Relay Pros ProTip:
Use the receiver relay to switch power to your device, or as a dry contact output. Perfect for extending contact closures over long distances.

MirX Contact Closure Over IP

MirX Network controllers send dry contact signals between two locations over your LAN. Both boards include inputs and relays. The input on each board controls the relay on the opposite board, providing true two-way control.

💡 Relay Pros ProTip:
Need gate control from both ends? Install a button at the gate to alert someone inside, then use a second button in the office to open the gate remotely.
