Ethernet Contact Closure 1-Way Transmitter Receiver Pair

Our MirC 2-Channel SPDT 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 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.  Operating over a local area network, MirC controllers are capable of finding each other directly.  Operating over the internet, MirC controllers report to our dedicated Amazon server to stay connected.  Our first prototype was tested between between Shanghai China and our office in Missouri back in 2008.  Since then, we have had years to improve our firmware and our server software to help ensure these devices stay connected whenever possible.

This pair of MirC controllers is equipped with your choice of 5-Amp or 10-Amp SPDT relays, ideal for use in most general purpose switching applications.  Ideal for lights, small motors, gate openers, and much more.  On-board Relay status LEDs and busy/ready LEDs let you know when these controllers are talking to each other.

Ethernet Network MirC Remote Contact Closure Transmitter and Receiver Controllers

No Computers, No Configuration – Works Right Out of the Box.  MirC controllers stay connected to each other using Ethernet network communications over your local area network or through the internet.  Inputs on the transmitting controller activate the relays at the receiving controller.

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.  MirC controllers will search your local area network or the internet until they find each other.

Syncing Up

Every MirC controller is equipped with contact closure inputs and relay outputs. The inputs on the transmitter activate the relays on the remote receiver using ethernet 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, there is a communication problem between the two devices.

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.  Since MirC includes relays on each side, local relays are typically used for verification purposes, such as limit switches or remote door switches, indicating the remote device has completed its control function.

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, available with optional wireless encryption
  • MirC Wired for hard-wired communication applications
  • MirC Network for local area Ethernet communications or use over the internet (internet communications uses our FREE server)

Our Mirror Family Controllers:

  • MirX consists of relays and contact closure inputs on each controller.  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.
  • MirM consists of a single contact closure input board and several remote relay controllers.
  • MirW consists of a single several contact closure input boards and a single relay controller.

MirC Relay Options

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:

10-Amp SPDT Relay Option

This controller is available with a 10-Amp relay option, allowing control of higher-power loads up to an absolute maximum of 240VAC at 10 Amps. Ideal for general purpose switching applications, this relays is focused on power-switching, and should never be used for low-power signals due to a higher On resistance of up to 150 Ohms when relay contacts are new (contact resistance drops to less than 1 Ohm after break-in period). The 10-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.  All connections are made via screw terminals, capable of accepting up to 12 AWG wire.

5-Amp SPDT Relay Option

This controller is available with a 5-Amp relay option, allowing control of higher-power loads up to an absolute maximum of 240VAC at 5 Amps. Ideal for general purpose switching applications, this relays is focused on power-switching, and should never be used for low-power signals due to a higher On resistance of up to 150 Ohms when relay contacts are new (contact resistance drops to less than 1 Ohm after break-in period). The 5-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.  All connections are made via screw terminals, capable of accepting up to 12 AWG wire.
