Wireless Contact Closure 1-Way Transmitter Receiver Pair
Our MirC 1-Channel High-Power Relay Controllers are manufactured in pairs, designed to work together when powered up using wireless communications. The contact closure input on the transmitter controls the relay on the receiving relay controller. Both the transmitter and receiving relay control display the relay status using LEDs. MirC controllers employ long-range wireless communications, we have tested line of sight range up to 2 miles. With rooftop antenna, ranges of 28 miles may be achieved. Urban and indoor installations typically achieve a 1,000 to 2,000 foot range, depending on type of building structure and wireless environment.
This pair of MirC controllers is equipped with your choice of 20-Amp SPDT or 30-Amp SPST relays, ideal for use in most high-power switching applications. Ideal for lights, motors, gate openers, pump controllers, valve controllers, and much more. On-board Relay status LEDs and busy/ready LEDs let you know when these controllers are talking to each other. When communications is lost, on-board relays will automatically deactivate within 30 seconds.
MirC Controllers Mirror Contact Closures in a Remote Location. A contact closure input is converted to a secure encrypted wireless signal and transmitted to a remote relay controller, which provides a remote contact closure output.
Wireless MirC Remote Contact Closure Transmitter and Receiver Controllers
Contact Closure Inputs in one location control remote relays in a remote location using a secure wireless encrypted signal. Mirror controllers are paired and ready to go to work immediately. No Computers, No Configuration – Works Right Out of the Box. MirC controllers stay connected to each other using wireless communications. Inputs on the transmitting controller activate the relays on the receiving controller.
Permanently Married
MirC is Always Trying to Talk to it’s Mate!
MirC controllers are always talking to each other. They stay in relentless communications for optimal reliability. Should they lose communication with each other, they will keep calling out for each other until they find their mate. Since MirC controllers are married to each other, it’s possible to have several MirC pairs in the same area without any significant interference.
Syncing Up
MirC controllers are equipped with contact closure inputs on the transmitter and relay outputs on the receiver. The inputs on the transmitter activate the relays on the remote receiver using wireless communications. The transmitter displays the status of the remote relays using LEDs (one LED per relay), so both the transmitter and receiver include relay status! 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.
Encryption
MirC Controllers are encrypted by default. This means a MirC controller will only speak to it’s mate on a secure channel. All MirC controllers use the same encryption key, and each MirC transmitter and receiver contain a unique serial number. Transmitters and Receivers are paired to only talk to the paired serial numbers.
Beacon Mode
Beacon Mode communicates with a Remote MirC controller many times per second, refreshing Relay Status information every time a valid data stream is received by the remote device. Relays are only refreshed when a valid data packet is received. If data is lost, the Ready LED will stay on and Relays will stay in their current state. If the remote MirC controller is in range, the Busy LED will flash periodically, indicating valid communications between devices. Beacon Mode is slower than Smart Mode and is used primarily for initial testing of two devices.
Smart Mode
Once you have determined an installation location for both MirC controllers, move the Beacon/Smart jumper to the Smart position. Smart Mode communicates to the remote device any time a change is detected on the local device. Otherwise, the controller periodically checks to make sure the remote device is in range. Smart Mode is significantly faster than Beacon Mode. Smart Mode is the preferred mode for daily use in most applications. Note that each MirC controller can be set to a different mode and jumper changes take effect immediately. Again, the Busy LED will indicate the remote device is properly communicating. Smart Mode will also verify the relays on the remote device are properly set. If they are not, Smart Mode will attempt communications until the remote device responds. If communications is lost between the MirC controllers, all relays will automatically shut off within 30 seconds. If this is not desirable, Beacon Mode should be used.
Beacon Mode vs. Smart Mode
Perhaps the most notable difference between Beacon and Smart Mode is how relays respond if communication is lost. In Beacon Mode, the relays will stay in their current state and will not change unless a new data packet is received. In Smart Mode, relays will turn off automatically in 10 to 30 seconds if communications is lost between MirC controllers.
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 two MirC controllers to see each other, it may be necessary to use larger antennas. We can provide signal repeaters for extreme circumstances, but this solution is generally not recommended unless absolutely necessary. Typical communication range in indoor or urban environments is 1,000 to 2,000 feet using the included antennas. Outdoor Line-Of-Sight Range is 4-9 miles using 2.1dB dipole antennas. Using high-gain antennas, 28 miles of wireless range may be possible in some Line-Of-Site locations.
Applications
MirC controllers are typically used by our large industrial clients for a wide range of remote control switching applications. Typical installations include remote gate operation, remote light control, remote pump control, as well as various temperature override applications. MirC controllers are typically used instead of expensive trenching and drilling applications where running wire can be destructive and sometimes cost prohibitive. MirC is commonly used in signage applications that may require a warning light as a supplement to a standard traffic light. MirC is also used by our customers to provide remote operation of lights, doors, gates, motors, pumps, and valves.

Notes
MirC devices are only sold as a permanently married pair, pricing shown on our web site indicates pricing for the pair of controllers. Contact Closure Inputs may only be connected to switches, buttons, or sensors with Contact Closure capability. Not suitable for use in voltage detection applications. MirC devices use Digi.com 900HP-S3B communications modules at 900MHz. Data is transacted using 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 MirC controller is unable to communicate to the remote device. A flashing busy LED is your verification that all communications are functioning properly between MirC controllers.
Customers who require inductive switching (such as motors, lights, pumps, solenoids, and Transformers) should visit the Induction Suppression portion of our web site.
No Voltage Input
Please Note: Users must NEVER apply any voltage to an input on the MirC controller, these inputs are for Contact Closure connections only.
No Voltage Output
Please Note: Relays provide a contact closure output. They do not provide a voltage output. On-Board relays will switch a voltage that is provided externally by the user.
