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