Analog input module of Siemens S7-300PLC, signal common ground - solution - Huaqiang Electronic Network

L0504-Murata muRata common mode inductor 90Ω 150mA

Siemens S7-300plc analog input module, 4-wire 4-20ma current signal and 0-10V voltage signal negative terminal, need to be shorted with 10,11, constitute the equipotential? I know the voltage needs to be common, that is, I don't know if the current signal is needed.
Answer: 1. Do you need to short-circuit with 10 and 11 to form an equipotential? I need to know the voltage. I don’t know if the current signal is needed.
need. Note that when using a grounded 4-wire sensor with a non-isolated power supply, there is no need to interconnect MANA and M- (terminals 11, 13, 15, 17, 19).
2, the sensor's 3 lines are connected to 24VDC, the module's 2, 3 terminals, of which 3 terminals are not shorted with 24--, so there is no problem?
In short, the three-wire system is wired in four wires. Because the three-wire sensor is the positive terminal of the power supply and the positive terminal of the signal output are separated, but they share a COM terminal, that is, the negative terminal of the signal output shares a line with the negative terminal of the power supply.
