Contract Closure Transmitter to Multiple Remote Relay Receivers

Dcube Store MirM series controllers consist of at least 3 circuit boards, sold as a group.  MirM uses contact closure inputs in one location to control relays in several remote locations.  Two 4-channel relay controllers are included in the basic configuration.  MirM controllers consist of a contact closure input board, shown at the bottom of the main product photos.  Simply connect buttons or switches to the contact closure inputs of the contact closure transmitter to control 4 relays in two different locations for a total of 8 relays.  The wireless range of MirM controllers is up to 2,000 feet indoors and in urban environments, or up to 1 mile in line-of-sight applications.

MirM controllers are ideal for applications that require a centralized control panel to control devices in several remote locations.  Up to 24 remote locations are supported by our MirM series transmitter.  We will automatically upgrade the transmitter for more inputs at no additional charge based on the number of remote locations you require.

This set of controllers includes two 4-channel relay boards with general-purpose SPDT relays installed, rated at 5 or 10-Amps (configured during purchase).  Please note that it is difficult to upgrade MirM in the future to include more relay outputs, as the main transmitter may need to be returned to us for the reprogramming of additional units.  Each MirM controller requires a 12VDC power supply.

2.4 GHz 802.15.4 Wireless Communications

The sender board and each receiver board are equipped with a Wireless 802.15.4 Module.  MirM operates at 2.4 GHz, so it’s not bothered by WiFi or other common signals.  The wireless module adds wireless communications to the board using an 802.15.4 wireless protocol and will only communicate with its paired modules.  The module is powered from the board and the board itself will require 12 volts of power and can be hard-wired or you can purchase a “wall wart” type transformer at checkout.

Who’s Qualified to Use the MirM Series?

The MirM Series Controllers are very friendly for first-time users.  They arrive pre-configured and ready to work once powered up.  Whether you are an electronics engineer or a home hobbyist, only a small amount of electronics knowledge is required to use the MirM Series controllers.

Contact Closure Inputs

The MirM transmitter has contact closure input on-board to control each relay at each location independently.  Inputs can be wired to trigger any of the relays at any of the remote locations in any combination.  The inputs are contact closure inputs only – no voltage can be applied to these inputs.  Buttons, switches, other relays, or other electronic devices can be used as an input and trigger the remote relays as long as no voltage is applied.

Relay Outputs

MirM Controllers have relays integrated into the receiver board for remote locations.  Relays do NOT provide a voltage output, they provide a contact closure output and simply control the power to the device you are switching.  Wiring to a relay will be slightly different depending on the model of MirM controller you choose.

Break-A-Way Tabs for a Smaller Design

The MirM Receiver Boards have a great feature where space is a premium – Break-Away Tabs.  The Break-Away Tabs allow most receiver boards to fit in an optional undrilled plastic enclosure.  Snap off the Break-Away Tabs and you have a receiver board with a smaller profile when you need to fit in a tight space.

Relay Cycles

MirM controllers are fast, capable of activating remote relays in less than a second.  MirM controllers were designed for long life, you should expect to get years of service from your controller and literally thousands of cycles from the relay(s) on board.  MirM controllers are covered under our 5-year industrial warranty, so you have problems, we’ll help get you going again.
