ifm SN0150 Flow Monitor Relay, 90–240 V AC, Flow, Temperature and Wire-Break Monitoring

Description

Product Overview
The ifm SN0150 is a DIN-rail-mounted control monitor for compatible flow sensors. It evaluates sensor signals to monitor flow and temperature and can detect specified wiring faults. The relay outputs allow the evaluation unit to communicate the monitored condition to a compatible control circuit.
The unit is designed for industrial monitoring applications where flow status, temperature thresholds, and sensor wiring integrity need to be evaluated from one device.

Applications
The ifm SN0150 may be used in compatible installations involving:
– Industrial flow monitoring
– Liquid flow monitoring
– Temperature threshold monitoring
– Flow sensor signal evaluation
– Industrial process control panels
– Sensor wiring fault monitoring
– Machine and equipment condition monitoring
The monitored medium and sensor configuration must match the manufacturer’s requirements. The device is an evaluation unit and does not replace the flow sensor itself.
Installation and Compatibility Guidance
Before purchasing, confirm that your flow sensor is compatible with the SN0150 and that the available supply is within 90–240 V AC. Check the terminal wiring, sensor configuration, power-on delay, and relay load limits.
The manufacturer specifies a fast-acting miniature fuse of no more than 5 A and recommends checking correct operation after a short circuit. Follow the official wiring diagram and applicable electrical safety requirements.
