Hi all,
I'm quite new to PLCs and instrumentation, but somehow I happen to be in responsibility of the instrumentation of a pipe system, involving some water tanks, pumps and different sensors.
I have this pressure sensor I am trying to connect to the analog module of the PLC, but I'm unable to get a decent reading of the output signal from the sensor, even with an amperemeter!
The technical specifications are as follows:
PLC: Mitsubishi FX3U w/ analog module FX2N-8AD
Sensor: DMP 457 (BD Sensors) 0-10 bar @ 4-20 mA
The sensor is connected as thus:
24V+ -> Vs+ [Sensor] Vs- -> I+ [PLC] COM -> 24V-
GND on the sensor is connected to the same ground as the analog module.
Could someone help out??
