Contact Closure to Multi-Point Relay 1-Channel 5-AmpMIRMR15
~~MirM Operations Have Changed~~Please Note: The 1 input on the MirMR15 sender board will now control all the relays on the remote boards. The remote relays are no longer independently controlled.
Contact Closure to Multi-Point RelayThe MirMR15 Contact Closure to Multi-Point Relay allows you to control relays in multiple locations from a contact closure (no voltage) input. Inputs on the sender board controls relays on multiple remote boards. There is 1 dry contact input on the sender board and 1 relay on each of the remote locations. When the contact closure circuit is closed on the input board all the relays on the remote boards will energize.

MirM boards operate reliably and efficiently when the antennas can “see“ each other. Obstructions like walls, buildings and even trees and hills can diminish the signal or prevent communication altogether. Metal being the worst for any wireless signal to penetrate with stone and brick and being a close second. Positioning the antennas for line-of-site operation will greatly increase reliability.
Wireless Relay to Multiple LocationsThe MIRMR15 has contact closure (no voltage) inputs(s) on the sender boards that will control relays on the receiver boards. When the contact closure circuit on the sender board is closed the relays on the remote boards will be energized. The relays will remain energized until the contact closure circuit opens. When the circuit opens the relay will turn off.
XBee-PRO 900 RF ModuleThe MIRMR15 boards are equipped with an 900HP Modules and are paired together using the serial numbers of the radios installed. The XBee-PRO 900 RF module is ideally suited for less power-hungry, low-latency point-to-point applications. Capable of point-to-point and peer-to-peer, the XBee-900 modules have a higher selectable transmitting power of 250mW. This higher TX power allows for line-of-sight range up to 15 miles with the right antenna. All range tests are conducted in clear line-of-sight installations. It is not possible for us to accurately predict range prior to purchase. We cannot predict range inside buildings, using google map images, or predict interference that may be present at your location that would prohibit proper operation.The module is powered from the board and the board itself will require 12 VDC power and can be hard wired or you can purchase a "wall wart" type Power Supply at checkout.
Line-Of-Site OperationAs with any wireless technologies, for optimal performance it needs to be line-of-sight. We can't stress this enough. In other words the antennas of the boards must "see" each other to get the optimal range or even be able to communicate at all. Obstructions like walls, buildings and even trees and hills can diminish the signal or prevent communication altogether. Metal being the worst for any wireless signal to penetrate with stone, brick and hills being a close second. Upgrading to a longer distance module will not mean that the signal will be able to penetrate these obstructions even at a short distance of a few feet.
Extension CableAn extension cable can be used position the antenna if needed. The cable should be no longer than 20' (6 m) to prevent signal loss. The antenna uses an RP-SMA connection or Reverse Polarity SMA connector.
Multiple MirM SetsMultiple sets of the MirM boardss can be used within range of each other. The boards are married together using the serial numbers of the wireless modules installed, meaning multiple pairs will not interfere with each other! Please note: When there are large numbers of devices using the same channels, there will be interference that can cause dropped communications. There are ways to combat this interference, there are a few things that can be done. Contact us if you are quoting a large job for more information.
Attention: No Voltage Input
Please Note: Users must NEVER apply any voltage to an input on the MirM Sender Board, these inputs are for
Dry Contact Connections ONLY.
MirM RelayMirM controllers are a point to Multi-point set of boards that allow you to control relays by using a contact closure (no voltage). Inputs on the sender board controls relays on multiple remote boards. The relays will remain energized as long as the contact closure input is closed, when the input opens the relay will turn off. Depending on the contact closure input that you are using you can momentarily keep the relay on or use an toggle switch can trigger relay on then off. The relays provide no voltage and can be used as a dry contact output if needed.
Sender BoardsThe MirM sender board is basically a contact closure (no voltage) input board. The board will have as many inputs as there are relays on the receiver board. The inputs will control the relays on the receiver boards. Input 1 will control all relay 1's on the receiver boards. Input will control all the relay 2's and so on.
No Voltage InputsContact closure inputs such as buttons, switches or other electronic devices (no voltage) attached to inputs on the sender board will trigger relays on the remote locations. The Sender has inputs while the Receivers have relays. When an input on the Sender is tripped by a contact closure a relay on a Receiver board is energized and will remain energized until the contact closure is released.
Receiver BoardsThe sender board can communicate wirelessly to Receiver Boards. These locations will have to be in range of the sender board which can be up to 2 miles (3.2km) line-of-sight. The remote locations will receive a command from the sender board when a contact closure input that is associated with the board is closed to energize a relay or a group of relays in different locations. When the Contact Closure circuit opens the associated relays will de-energize or turn off. Additional remote locations can be added at a later date but all married boards in the system will need to be sent back for configuration.
2-Million CyclesMirW series controllers are designed for long life, you should expect to get years of service from your controller and literally 2-million cycles from the relays on board. With a 5-year warranty and a money back guarantee you have nothing to loose! Place your order now, while everything is in front of you.
SPDT Relay InstalledThe Receiver Board has SPDT relays installed. SPDT Single Pole Double Throw Relays have three connections - Common, Normally Open, and Normally Closed. When the relay is off, the common is connected to the normally closed connection of the relay. When the relay coil is energized, the Common swings over to the Normally Open Connection of the Relay. You can wire the device you are switching to either the Normally Open or the Normally Closed position using screw terminal connections. The maximum guage wire the terminal can handle is 14 ga but we have used up to 12 ga solid core for several applications with no issues.
Break-A-Way Tabs for a Smaller DesignThe MirW sender boards have a great feature where space is a premium - Break-A-Way Tabs! The Break-A-Way Tabs allow most boards to fit in an optional undrilled plastic enclosure. Snap off the Break-A-Way Tabs and you have a board with a smaller profile when you need to fit in a tight space.

Induction CapacitorsPerhaps the most overlooked aspect of relay control is proper handling of inductive loads. Inductive loads are anything with a magnetic coil, such as a motor, solenoid, or a transformer. Controlling a inductive load using these boards requires induction suppression capacitors to absorb the high voltages generated by inductive loads, blocking them from the contacts of the relay. Without this capacitor, the lifespan of the relay will be greatly reduced. Induction can electrically interfere with the microprocessor logic of the boards, causing relay banks to shut down unexpectedly. If this happens the boards may need to be power cycled to restore communication. Capacitors are available at checkout, for more information and drawings view our Induction Suppression Page.
Power Supply AvailableThe PWR12 is regulated power supply providing clean power necessary for the performance of these boards. The PWR12 US power supply is a 120VAC to 12VDC 1.25A 60Hz regulated power supply and it plugs into the barrel connector on the board. The output connector is a 2.1mm I.D. x 5.5mm O.D. x 9.5mm R/A barrel connector.

Induction SuppressionControlling an inductive load using our relay controllers requires the use of induction suppression capacitors. The purpose of this capacitor is to absorb the high voltages generated by inductive loads, blocking them from the contacts of the relay. Without this capacitor, the lifespan of the relay will be greatly reduced. Induction can be so severe that it electrically interferes with the microprocessor logic of our controllers, causing relay banks to shut themselves down unexpectedly. Click Here for More
