Could I connect 2 wire transmitter on 4 wire Analog Input module ET200S(4-20ma).

or for 2 wire transmitter must to take  4 wire Analog Input module.

Please guide.

Hi,

Could you give us reference of your analog input module ?

Normally, 4 wires analog inputs card has 2 wires to power transmitter and 2 wires for measurement.

With 2 wires transmitter, power supply come from external and the 2 other wires are for measurement. So on you card you have just to connect the 2 wires for measurement and leave the 2 wires for supply not connected.

Regards.

Hello,

2 wires transmitter is powered by the loop current.
4 wires transmitter is powered by an external supply.
