Installation and Specifications:
1. General:
The MR16out processor provides a solution to the OEM system integrator for output control. The
controller has 16 form-C contact relays for load switching. Additionally, 2 digital inputs are provided for
tamper and power fault status monitoring. The processor requires 12 to 24Vdc for power.
2. Supplying Power to the MR16out:
The MR16out requires 12 to 24Vdc for power on TB11. Locate power
source as close to the unit as possible. Connect power with minimum of
18AWG wires.
Observe POLARITY on VIN!

3. Communication Wiring:
The MR16out communicates to a controller via a 2-wire RS-485 interface. The interface allows multi-drop
communication on a single bus of up to 4,000 feet (1,200 m). Use twisted pair (minimum 24 AWG) with
shield for the communication line.
Install the following jumpers for the RS-485 interface according to the selected configuration:
4. Inputs for Cabinet Tamper/Power Fault:
Input CT and input BA are used for monitoring cabinet tamper and power failure with normally closed
contacts. These two inputs are for contact closure monitoring only, and do not use EOL resistor(s). If
these inputs are not used, install a short piece of wire at the input to indicate a safe condition.
5. Relay Outputs:
The following diagrams show typical use of the relay. A DC power source is recommended whenever
possible. Transient clamping must be provided to protect the contacts and to reduce EMI emission. Use
sufficiently large wires for the load current to avoid voltage loss.
