Ethernet Contact Closure 1-Way Transmitter Receiver Pair
Our MirC 1-Channel High-Power Relay Controllers are manufactured in pairs, designed to work together when powered up using Ethernet communications over a local area network or over long distances using the internet. The contact closure input on the transmitter controls a relay 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.

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).
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.
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 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.
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.
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.
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
MirC offers several relay options, depending on your application. We stock solid-state, high-power, and general purpose relays in our MirC line of products. However, we can customize our MirC controllers to your exact needs. Please contact us if you need any custom designed MirC controllers, including different relay types or firmware modifications. This particular controller has the following relay options available:
20-Amp SPDT High Power Relay Option
This controller is available with a 20-Amp relay option, allowing control of high-power loads up to an absolute maximum of 240VAC at 20 Amps. Ideal for high-power switching applications, this relay should never be used for low-power signals. The 20-Amp relay is of the SPDT variety, which provides Common (C), Normally Open (NO), and Normally Closed (NC) connections. Common is connected to NC when the relay is off. Common disconnects from NC and connects to NO when the relay is activated. This relay is Rated at 20-Amps between NO and C. Do not exceed 10-Amps between C and NC connections. This relay uses .250″ Quick Connect terminals (optional accessory) to connect to the top side of the relay. The relay is molded with COM, NC, and NO markings into the plastic. Review Datasheet
30-Amp SPST High Power Relay Option
This controller is available with a 30-Amp relay option, allowing control of high-power loads up to an absolute maximum of 240VAC at 30 Amps. Ideal for high-power switching applications, this relay should never be used for low-power signals. The 30-Amp relay is of the SPST variety, which provides Common (C) and Normally Open (NO) connections. Common has no connection when the relay is off. Common connects to NO when the relay is activated. This relay uses .250″ Quick Connect terminals (optional accessory) to connect to the top side of the relay.
