The Simplicity of MirC, The Security of Bluetooth
No Computers, No Configuration - Works Right Out of the Box
Contact Closure Inputs Control Relays in a Remote Location - Wirelessly
Reliable Communications Between Two Devices That are a Married Pair
Contact Closure Over a Distance
MirC controllers are sold in pairs. Contact closure devices such as buttons and switches attached to inputs on the first controller will trigger relays on the second controller. One controller is the Sender and the other is the Receiver. The Sender has inputs while the Receiver has relays. When an input on the Sender is tripped by a contact closure the corresponding relay on the Receiver board is energized. Communication between the Sender and Receiver is achieved using Bluetooth Wireless. Pricing shown on our web site indicates pricing for the pair of controllers.
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.
Each board is equipped with a Bluetooth Module. The module adds Bluetooth wireless communications to the boards and will only communicate
with it's paired module. The module is powered from the board and the board itself will require 12 volts of power and can be hard wired or you can purchase a "wall wart" type transformer at checkout.
Once you add your order to the shopping cart you will have the opportunity to choose a basic internal antenna or an extended range external antenna. 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. Hills, Trees, and Buildings will greatly reduce communication range of all wireless devices, so practical distances may be less.
As with any wireless technologies, for optimal performance it needs to be line-of-sight. In other words the antennas of the board and modem must "see" each other to get the optimal range or even be able to communicate at all.
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.
Order of Operations
- Contact closures are read on one controller
- Data is sent to other controller wirelessly to turn on or off relays
- Remote device replies back
- Busy light flashes to confirm data was received at the other end
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.
Mir-X 8-Input Screw Terminal - 8 inputs are only available on 8-Channel Mirx boards
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.
