Contact Closure Over a Distance

 Contact Closure RelayMirC controllers are sold in pairs, a sender board and receiver board.  Contact closure inputs such as buttons, switches or other electronic devices (no voltage) attached to inputs on the sender board will energize the corresponding relay on the Receiver board.  Communication between the Sender and Receiver board is through a three wire connection.  Pricing shown on our web site indicates pricing for the pair of controllers.

Go Where Wireless Won't Reach

MirC boards with a wired connection should be used in applications where wireless is not an option.  Direct wired applications are advisable between thick masonry walls, steel, or underground installations where a wireless signal won't travel or in areas where there may be interference.  MirC_ZRS controllers are also suitable in applications where security may be a concern.

Who’s Qualified to Use the MirC Series?

Anyone.  The MirC Series Controllers are the most consumer-friendly devices we have ever manufactured.  Whether an electronics engineer or a home hobbyist, anyone is qualified to use the MirC Series controller provided the Quick Start Guide is carefully studied.  The Quick Start Guide is available in the resources section to the right or bottom of this page.

ZRS ModulesZRS-A Module

Each board is equipped with a ZRS Module.  The ZRS Modules will be physically wired together using the screw terminal located on the module.  A Quality cable such a s twisted pair Cat 5 or Cat 6 is ideal with a working range of 1000 feet between controllers.  The module is powered from the board and each board will require 12 volts of power and can be hard wired or you can purchase a "wall wart" type Power Supply at checkout.

Read Status of Remote Relays

The sending device is also equipped with LEDs that display the status of the remote relay.  Status information is verified using 2-way wireless 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.

Contact Closure Inputs

A MirC controller has as many inputs on the sender board as it has Relays on the receiver board.  So a pair of 4 relay MirC controllers will have 4 contact closure inputs on the sender board and 4 relays on the receiver board, the same holds true for 1, 2, and 8 relay versions.

Relay Outputs

MirC 4-Output Screw Terminal with Normally Open, Normally Closed and Common are available for each relay. 20 and 30 amp boards will connect directly to the relays. The 30 amp is a SPST relay and only has Common and normally open.
MirC Controllers have 1, 2, 4, or 8 Relays integrated into the receiver 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 and simply interrupt the power to the device you are switching. Wiring to a relay will be slightly different depending on the model of MirC controller you choose.
