hi vivky bhau, did you have a look in the manual of the module? SIMATIC ET 200SP analog input module AI 8xI 2-/4-wire BA the difference between 2-Wire and 4-wire-transducers is that the 2-wire-transducers have their power supply through the measurement-wires. Thats the reason why only 4..20mA-range can be used with it. hope this helps, regards, |
