Selecting the Proper Amperage

For more information on selecting a board with the correct relay amperage for your application see Choosing a Proper Amperage.

Point to Multi-Point Relay

MirM Point to Multi-Point Relay Boards allow you to control relays in multiple locations from a contact closure (no voltage) input.  Inputs on the sender board controls relays on multiple remote boards.  Each relay in each location can be controlled independently and you can have up to twenty-four 1-channel remote locations.  The inputs can be wired to control relays in any combination to any location.  You now have total contact closure control in multiple locations for kill switches, sirens, lights, or even extending one contact closure to multiple locations!

2.4 GHz Communications

Point to Multi-Point RelayThe sender board and each receiver board is equipped with a Wireless XB24-AWI-EXT module that adds a wireless interface to the boards.  The 2.4 GHz 802.15.4 communications module adds wireless communications between the boards.  This module has a 1-mile (1.6 kilometer) wireless range, line-of-sight.

Selecting a Point to Multi-Point Relay

What amperage relay do you need?  The 1-channel MirM boards boards below have one relay installed on each receiver board.  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.  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.
