Secure Wireless Mir-C Relays
Unique Contact Closure Switching

Mir-C Relays are equipped with firmware built into the board that will allow you to connect contact 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 Contact Closure Relay Controllers 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!

Reactor Relays

Reactor Relay Controller
Reactor controllers trigger relays automatically based on inputs
Category Link: Reactor Controllers
Reactor Relay Controllers are configured using the included Reactor Configuration Utility. Once configured, the controller works without a computer connected, allowing analog inputs to trigger relays according to the configuration. The Reactor Relay was developed to address the needs of customers who need a controller capable of making intelligent decisions without a computer.

Two Boards Working Together

Mir-C controllers 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 devise 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 other controller to turn on or off relays, remote device replies back, busy light flashes to confirm data was received at the other end.

Bluetooth Wireless Range

The distance between MirC controllers will affect reliable operation. MirC controllers will offer better range if two MirC controllers are within line of sight of each other. If it is not possible for 2 MirC controllers to see each other, more expensive communications options will improve working distance for most users. You can expect MirC devices to function properly in most applications between 100 feet and up to 300 feet depending on communications module and antenna options chosen. Bluetooth MirC controllers are available with 2 options. The default option is the "Standard Range", which operates up to 100 feet and includes a small integrated antenna that cannot be moved or positioned. The "300 Foot Range" option offers communication between devices up to 300 feet apart (line of sight) and includes a small external antenna.

Contact Closure

Mir-C 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 Series Controllers are the most consumer friendly devices at Relay Pros. Weather you are an electronics engineer or home hobbyist, anyone is qualified to use the Mir-C Series controller

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 devices use Bluetooth, 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 controller is unable to communicate to the remote device. A flashing busy LED is your verification that all communications are functioning properly between Mir-C controllers.

Multiple Mir-C Pairs?

Multiple Mir-C Controllers can be used in one locations. One Pair of Mir-C controllers will not interfere with another Mir-C pair as they are isolated through the way they are designed. Mir-C Devices are paired together before shipment and will only communicate to each other, for this reason they will not interfere with other Mir-C controllers.

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 controllers 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 Controllers have 1, 2, 4, or 8 Relays integrated into the circuit board. A relay is similar to a switch. The only 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 controllers you choose.
