Mir-X Contact Closure Relay
No Computers, No Configuration - Works Right Out of the Box
Inputs on One Controller Activate the Relays at the Other Controller
Wired, Wireless or Ethernet Communications Available
Two Boards Working Together
Every MirX controller is equipped with contact closure inputs and outputs. The inputs on one controller activate the relays on the remote device using wireless communications. The "X" in MirX refers to the crossover. Since both devices are equipped with contact closure inputs and relays, each device targets and controls the remote device.
MirX devices are only sold as a permanently married pair, pricing shown on our web site indicates pricing for the pair of controllers.
Mir-X devices feature SPDT & SPST relays in four different amperage options and are available with the same number of contact closure inputs as there are relays installed on the 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-X Series?
Anyone. The Mir-X 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-X Series controller.
Each 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 two devices, the sending device will turn off the LED. Additionally, every MirX 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-X devices use 802.15.4 wireless, 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-X controller is unable to communicate to the remote device. A flashing busy LED is your verification that all communications are functioning properly between Mir-X controllers.
Multiple Mir-X Pairs?
Multiple Mir-X Controllers can be used in one locations. One Pair of Mir-X controllers will not interfere with another Mir-X pair as they are isolated through the way they are designed. Mir-X Devices are paired together before shipment and will only communicate to each other, for this reason they will not interfere with other Mir-X controllers.
Contact Closure Inputs
A Mir-X controller has as many inputs as it has Relays. So a pair of 4 relay Mir-X controllers will have 4 relays on each board and 4 inputs on each board which are used for controlling the relays on the opposite 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
Mir-X 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. For more click here
Mir-X 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-X controllers you choose.
