Wired Contact Closure Switching
The MIRCR230_ZRS relays are a set of two boards, a sender board and a receiver board. The Contact closure input on the sender board controls the relay on the receiver board using a three wire connection. Close the contact closure on the sender board and a relay will trigger on the receiver board - it's just that simple! Contact closure inputs such as buttons, relays, switches or other electronic devices (no voltage) attached to inputs on the sender boards will trigger the relays on the receiver board.MirCR230_ZRS The Ideal Choice
The MIRCR230_ZRS Contact Closure Relay is an ideal choice for a wired contact closure switch. The boards can communicate up to 1000 feet for reliable contact closure switching.![Processing... Processing...](../images/img_ajax_processing.gif)

Go Where Wireless Won't Reach
MirC boards with a wired connection are designed to 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.ZRS Modules

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 to turn on or off relays
- Remote device replies back
- Busy light flashes to confirm data was received at the other end
What Happens When Communication is Lost
A common question we receive is what happens to the relay that is energized and communication between the boards is lost. The relay can remain energized or on until communication is re-established or the relay can de-energize or turn off. This is done by a simple jumper on the board and setting it to Beacon or Smart mode. Regardless of the Mode you choose, if the busy LED flashes, the two devices are communicating properly. If the Busy LED does not flash at all, the devices are unable to communicate.Dry Contact Input ONLY
Please Note: Users must NEVER apply any voltage to an input on the MirC Sender Board, these inputs are for
Dry Contact Connections ONLY.
MirC Relay
This pair of boards allows you to control a relay using a dry contact (no voltage). The dry contact can come from a manual switch, a sensor or device that provides a contact closure, or another relay. As long as the contact closure circuit is closed the relay will remain energized or on. When the circuit opens the relay will de-energize or turn off. Meaning the relay will respond to a toggle or momentary connection depending on what type of input you select. Each MirC pair is ready to stand up to rigorous demands from heat, cold or vibration. Take it from us, these controllers will hold up!Status of Remote Relays

Contact Closure Inputs
The inputs on these boards accept a dry contact only - no voltage. Users must never apply any voltage to an input on either of the MirX Controllers.Relay Outputs
Relays do NOT provide a voltage output and can be used as a dry contact. They provide a contact closure output and simply interrupt the power to the device you are switching. The relays are rated for 240 VAC or 24 VDC. See the Data Sheets tab above for the specs on relays installed.SPST Relay Installed
