Contact Closure to Multi-Point Relay

MirM Contact Closure to Multi-Point Relay allows 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.  The relays will remain energized as long as the contact closure input is closed, when the input opens the relay will turn off.  Depending on the contact closure input that you are using you can momentarily keep the relay on or use an toggle switch can trigger relay on then off.  The relays provide no voltage and can be used as a dry contact output if needed.

900 MHz Communications

The sender board and each receiver board is equipped with a Wireless 900HP module that adds a wireless interface to the boards.  The 900 MHz communications module adds wireless communications between the boards.  These boards have a 2-mile (3.2 kilometer) wireless range, line-of-sight.
