Control Without Pulling Wire

Wireless MirX controllers give you instant contact-closure mirroring without running cables, trenching, or rewiring. Set them up once, and they stay synced - simple, reliable, and ready for real-world automation.

Flip a switch here and trigger a pump, gate, door lock, irrigation system - or flip one there and control something back here. Send clean dry-contact control across long distances without trenching, conduit, or cable runs.

Contact Closure Relay Control

MirX controllers let you send dry contact (no voltage) signals between two locations - without running wires. Each system includes two identical boards, and each board features:
  • Contact closure inputs
  • Relay outputs
Inputs on either board activate the relays on the opposite board, allowing two-way remote control.

How It Works

Use either board's relay to switch power to your device or as a dry contact output. Perfect for applications where contact closure control is needed at both locations across long distances.

Simple Setup

Contact Closure Relay
  • Connect your device's contact closure output to either MirX board
  • Wire the opposite board relay to your equipment at the remote location
  • Activate the closure → remote relay responds almost instantly
  • Repeat in reverse for control from the other location

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 MirX 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
