Contact Closure to Multi-Point Relay

Contact Closure Relay MirM controllers let you send a dry contact (no voltage) signal from one location to multiple remote relay boards at the same time. Each system uses a Sender Board with contact closure inputs and two or more Receiver Boards with matching relay outputs.

When an input on the Sender Board is activated, the corresponding relays on all paired Receiver Boards respond simultaneously.

This makes MirM ideal for applications where the same action needs to occur in multiple locations using a wired, wireless, or Ethernet connection.

How It Works

The relays on each Receiver Board provide no voltage and can be used to switch power to a device or as a dry contact closure output.

Relays remain energized as long as the input stays closed. A momentary push button can briefly activate the relay, while a maintained switch can hold the relay on until opened.

900 MHz Communications

Each Sender Board and Receiver Board is equipped with a Wireless 900HP module for reliable long-range communication.

These systems offer up to 2 miles (3.2 km) line-of-sight range, making MirM a strong solution for farms, facilities, gates, pumps, alarms, and multi-building control.

Choosing the Right Contact Closure Relay

How many relays do you need? Below, you'll find a list of available MirM boards, categorized by the number of relays installed on the board. Simply select the number of relays you require, and click the corresponding link. You'll then be directed to a page where you can choose the amperage of the relay installed on the board.

Choose how many inputs/relays you need, then choose how to communicate.
