Remote Relay Switch
Unique Contact Closure Switching

Mir-C Remote Relay Switches are equipped with firmware built into the board that will allow contac t closure inputs to control contact closure outputs in a remote location. The sending device is equipped with contact closure inputs, used to control relays on the remote device. The sender and Receiver controllers are a permanently married pair and are both included when you purchase a Mir-C.

No Set-up, No Configuration...
Works Right Out of the Box!

The Mir-C Remote Relay Switches are ready to go to work right out of the box. Just Simple, Reliable Communications between two devices. Simply connect a Contact Closure input and the relay on the remote board will trigger!

Two Boards Working Together

Mir-C Remote Relay Switches are really two boards that allow contact closure inputs on the first board to control relay outputs on a second board. The sending device is equipped with contact closure inputs, the receiving device is where the relays are. Both sender and relay devices are included when you purchase a Mir-C pair. Contact closures are read on one controller, data is sent to the other controller to turn on or off relays, the remote device executes the command sent to it and replies back, busy light flashes to confirm data was received at the other end.

Relay Status

Mir-C Remote Relay Switch devices feature SPDT & SPST relays and are available with the same number of contact closure inputs on the sender as there are relays installed on the remote device.  Contact Closure Inputs may only be connected to switches, buttons, or sensors with Contact Closure capability.  Not suitable for use in voltage detection applications.

Who's Qualified to Use the Mir-C Series?

Anyone. The Mir-C Remote Relay Switch devices are the most consumer friendly devices on our site. Whether you are an electronics engineer or home hobbyist, anyone is qualified to use the Mir-C Remote Relay Switch

Relay Status

The sending device is also equipped with LEDs that display the status of the remote relay. Status information is verified using 2-way communications. If communication is lost between the remote relay and the sending device, the sending device will turn off the LED. Additionally, every MirC controller is equipped with a Busy/Ready LED. If the Busy LED flashes, this indicates the remote device has successfully received and accepted your contact closure status. If the Busy LED does not flash, the remote device is out of range.

Communication Between Boards

Mir-C Remote Relay Switch devices use 802.15.4, wired and Ethernet two-way communications to ensure the remote device is properly functioning. The Busy LED is always used to indicate a properly functioning remote device. If you do not see the Busy LED flash, then the Mir-C Remote Relay Switch is unable to communicate to the remote device. A flashing busy LED is your verification that all communications are functioning properly between Mir-C Remote Relay Switch.

Multiple Remote Relay Switch Pairs?

Multiple Mir-C Relay Switches can be used in one location. One Pair of Mir-C controllers will not interfere withanother Mir-C pair as they are isolated through the way they are designed. Mir-C Remote Relay Switches are paired together before shipmentandwill only communicate to each other, for this reason they will not interfere with other Mir-C Remote Relay Switches.

Contact Closure Inputs

A Mir-C Sender controller has as many inputs as its mating Mir-C Receiver has Relays. So a pair of 4 relay Mir-C Remote Relay Switches will have 4 relays on the Receiver board and 4 inputs on the Sender board which are used for controlling the relays on the Receiver Board, the same holds true for 1, 2, and 8 relay versions. Users must NEVER apply any voltage to an input on the Mir-C Sender controller, these inputs are for Contact Closure connection only.

Relay Outputs

Mir-C Remote Relay Switches have 1, 2, 4, or 8 Relays integrated into the circuit board. A relay is similar t o aswitch.Theonly difference between a switch and a relay is the actual mechanism for changing the on/off status of the switch. On a switch, you manually push on a piece of metal or plastic to operate the switch. On a relay, an electric current is used to operate the switch. Relays do NOT provide a voltage output. They provide a contact closure output, exactly like the terminals found on a light switch at your local hardware store. Wiring to a relay will be slightly different depending on the model of Mir-C Remote Relay Switch you choose.

Communication Options:

MirC Remote Relay Switches Offer three Communications Options, Including 802.15.4 wireless, wired, and Ethernet communications.

1-Way Remote Contact Closure Control: MirC
