PLC analog wiring:

Two-wire system: The positive pole of the power supply is connected to that of the transmitter, and the negative pole of the transmitter is connected to the AD side, and the negative pole of the power supply is connected to the GND. Generally it is the wiring method of the 4-20MA/0-20MA transmitter.

Three-wire system: The positive pole of the power supply is connected to that of the transmitter. The negative of the power supply and that of the signal output are the same terminal. The transmitter signal output is connected to the AD terminal.

Four-wire system: The positive and negative terminals of the power supply are connected to those of the transmitter respectively, and the positive and negative of the transmitter signal outputs are connected to the AD and the GND terminal respectively.

The two wires of the temperature analog are connected to the AD and the GND terminal respectively. If it is a three-wire PT100, it needs to be connected in two lines. The GND common terminal of the analog input and output can be shared.

PLC digital inputs wiring:

Ports short circuit: S/S of PLC input terminal is connected to 24V, X terminal is connected to power supply 0V, i.e., input signal.

Two-wire system (magnetic control switch): The positive pole of the magnetic switch is connected to PLC X terminal, and the negative pole is connected to 0V.

Three-wire system (photoelectric sensor or encoder): Sensor or encoder power supply is connected to power supply positive, signal line is connected to X terminal. Encoder and photoelectric sensor are NPN type (PNP is customized).

PLC digital outputs wiring:

Transistor: Output is NPN, COM is connected to the negative pole, and Y is connected to the positive pole of the power supply with a load.

Relay: Dry contact output, COM can be connected to the positive or negative.
