Operation:
The Marine DIN Rail switch monitor provides four input states to the control equipment: normal, fault, pre-alarm and alarm. The unit has a red LED to indicate an alarm and a yellow LED to indicate a fault condition. The Marine DIN Rail switch monitor is loop-powered and operates at 17-28V DC with protocol voltage pulses of 5-9V. The unit is designed to accept a maximum line resistance of 50ohm. The end-of-line resistor required is 20k ohm.
Apollo Marine DIN-Rail Switch Monitor Plus – 55000-772MAR
The Marine DIN-Rail Switch Monitor Plus is designed to monitor the state of one or more single pole, volt free contacts connected on a single pair of cables and to report the status to Apollo compatible analogue control equipment. In addition, it incorporates additional circuitry to monitor flow switches and provide a time delay in so doing. It also contains circuitry which can be used to reset a beam detector.
