Mir-C Series Remote Relay Switch
Contact Closure Inputs on Sender Device
Relay Outputs on Receiver Device
Wired, Wireless or Ethernet Communications Available
Two Boards Working Together
Mir-C Remote Relay Switches are really two boards that allow contact closure inputs on the first board to
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.
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.

Find the board you need by using the interactive menu below. The Communication Protocols are to the left, this is how the two boards
will communicate with each other. Once you decide how they will communicate then select the number of contact closure inputs/relays
you would like on the boards. You will be taken to another page where you can simply simply select the board with the correct amperage for the item you
Find the board you need by using the interactive menu to he right. Hover
over the Button and select the communication protocol and then the number of inputs/relays you would like installed.
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
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.
Mir-C Remote Relay Switches have 1, 2, 4, or 8 Relays integrated into the circuit board. A relay is similar t
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.
MirC Remote Relay Switches Offer three Communications Options,
Including 802.15.4 wireless, wired, and Ethernet communications.
