Wiring of Siemens PLC EM235

Thread Content

I would like to ask everyone how to wire a Siemens PLC EM235? For 4-20mA signals, for example, where should temperature signals AI be connected? Is the AO signal similar to the 4-20mA signal of a control valve? Thank you all

RX and X+ are shorted together and then connected to AI+, X- is connected to AI-, and M is connected to the negative terminal of the power supply
