can ET200 be used in view of the two types of analog inputs 2-wire passive (loop power) and 4-wire active?

hi G_R_E_Y,

a 4-wire-transducer just means it has 2 wires for an extra powersupply, while 2-wire devices get their power from the measuring wires.

The showed wiring from the manual just means that the supply voltages has to be on the same potential( same M-potential). Then you just need to connect the measuring wires "+" with "I+" and "-" with "M" to the M-potential.

hope this helps,

regards,

Hello mopS04

I have a lot of analog input with two type, 2-wire passive(loop power) and 4-wire Active.

can I use this module considering the two types analog input 2-wire passive (loop power) and 4-wire Active?

best regards

Split from 4-wire signal into 2-wire AI module (ET200SPHA).
