Wireless Contact Closure Control

MirM controllers allow contact closure inputs to control relays in remote locations using multiple relay boards.  The sender board is equipped with contact closure inputs, used to control relays on the receiver boards.  Both sender and up to 12 4-Channel remote receiver boards are included when you purchase the MirM Series boards.  MirM boards are wireless with a range of up to 1-mile (1.6km).  As with any wireless technologies, for optimal performance it needs to be line-of-sight to get the optimal range or even be able to communicate at all.  All boards are equipped with a small external antenna which can be moved or positioned for optimal range.

Selecting a Wireless Contact Closure Relay

MirM boards boards below have one relay installed on the receiver boards.  Each set will have a sender board with enough inputs to control all relays at all locations independently.  Select the amperage of the relays installed on the remote boards and the type of relay below.  Choose the controller that fits the amperage you are switching.  Below you will find SPDT relays in the 5, 10 and 20 amp versions and an SPST version with 30 amps.  For more information on selecting the correct relay for your application see Choosing a Proper Amperage.
