Ethernet Contact Closure 1-Way Transmitter Receiver Pair
Our MirC 4-Channel Solid-State Relay Controllers are manufactured in pairs, designed to work together when powered up using Ethernet communications over a local area network. The contact closure inputs on the transmitter control relays on the remote receiver. Both the transmitter and receiver display the status of the relays using LEDs. MirC controllers consist of custom firmware that keeps this married pair of controllers in constant communications with each other.
Customize this MirC controller for the type of solid-state relays your application requires during the order process. Solid-state relays are of the SPST variety, and are typically used for high-reliability and long-life AC or DC switching applications. Remotely control motors, pumps, valves, solenoids, lights, and other heavy duty electrical equipment by simply wiring a switch in one location to control your electrical equipment in a remote location. On-board Relay status LEDs and busy/ready LEDs let you know when these controllers are talking to each other.

Important Change Notice
This Device no-longer communicates over the internet due to changes in technology. Please contact us for a internet connected solution if required.
MirC Controllers Mirror Contact Closures in a Remote Location. A contact closure input is transmitted over a Ethernet network and transmitted to a remote relay controller also equipped with a Ethernet connection, which provides a remote contact closure output.
Ethernet MirC Remote Contact Closure Transmitter and Receiver Controllers
Contact Closure Inputs in one location control remote relays in a remote location using Ethernet network communications. Mirror controllers are paired during initial configuration, ensuring peaceful co-existence on your network. MirC controllers stay connected to each other using Ethernet network communications. Inputs on the transmitting controller activate the relays on the receiving controller. The Ethernet interface supports DHCP as well as static IP addresses (IPv4). For used in a Local Area Network only (not for use over the internet).
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.
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 Ethernet network 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 not properly connected.
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 communicating. 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.
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.
Other Mirror Family Controllers
- MirX consists of relays and contact closure inputs on each controller (local and remote). Inputs in the home location control the relays in the remote location. Inputs in the remote location control the relays in the home location.
- MirC is the same as MirX except MirC consists of contact closures on one controller and relays on the remote controller.
- MirW consists of several contact closure input boards and a single relay controller. All remote contact closure inputs are used to control local relays.
MirC Variations
NCD manufactures several variations of MirC as well as other Mirror series devices. Here are some variations you may wish to consider:
- MirC Wireless for remote control applications with Wireless Encryption
- MirC Wired for hard-wired communication applications
- MirC Network for local area Ethernet communications in a Local Area

Induction Suppression
Learn about Induction and how it comes into play with Relay Controllers. Induction suppression can make your Relay Control applications intermittent and unreliable. This video will show you what causes it, how to avoid it, and how to account for it in your application.
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 the Lantronix XPort Pro with custom firmware. 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.
Ethernet TCP/IP Compatibility Notes
This device periodically sends UDP Packets on port 13,000, which help identify the IP address of this device on your network.
Choosing a Solid State Relay
Please examine the datasheet of each solid state relay carefully, as SSRs do not function exactly like mechanical switches. SSRs frequently have minimum load requirements, and some require external snubber circuitry for certain applications. SSRs do not typically work with volt meters in the same way as mechanical switches. SSRs must also be chosen for AC or DC applications, as they are not universally interchangeable. Some SSRs require forced air cooling, and may be damaged if not properly ventilated. Please consult the experts at Crydom.com if you are uncertain about your choice of SSR.
