Wireless Contact Closure Relay

MirC Wireless Contact Closure Relay has two boards, a sender board with contact closure (No Voltage) inputs that controls relays on the receiver board.  Both sender and receiver boards are included when you purchase a MirC pair.

Contact Closure Input & Output

The relays on the receiver board can be used to interrupt the power of a device you are switching and also as a dry contact closure output.  Applications where you need to extend the range of a contact closure over a distance the MirC will work.  Connect the Contact Closure output of your device to the Sender Board then wire the relay on the Receiver Board as your contact closure input in a remote location.

XBee-PRO 900 RF Module

The sender board and 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.  This module has a 2-mile (3.2 kilometers) wireless range, line-of-sight.
