Marine DIN-Rail Switch Monitor Plus

Product code: 55000-772MAR

55000-772MAR - Marine DIN-Rail Switch Monitor Plus
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.
Full Details
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 50Ω. The end-of-line resistor required is 20kΩ.
