MR16in PROCESSOR
Installation and Specifications:
1. General:
The MR16in processor provides a solution to the OEM system integrator for sensor monitoring and output
control. The MR16in has 16 supervised inputs and 2 form-C contact relays for load switching. In
addition, 2 digital inputs are used for cabinet tamper and power fault status monitoring. The processor
requires 12 to 24Vdc for power.
2. Supplying Power to the MR16in:
The MR16in accepts 12 to 24Vdc for power. Locate power source as
close to the unit as possible. Connect power with minimum of 18AWG
wires.
