Terminal function description
name
GND Analog ground, internally isolated from COM
Analog input 4
AI4
Input 0~10V: input impedance 22KΩ
+24V, PT, PLC and digital input and
COM
output public terminal
Provides +24V power supply to the outside,
generally used as digital input and output
24V
terminal working power supply and external
sensor power supply
Digital input power terminal
It is used for switching between high and low
level of switch input. It is short-circuited with
+24V at the factory, that is, DI is active at low
PLC level.
When the external power is input, disconnect
the PLC from the +24V.
It is a separate network from the PLC on the
IO board and is used separately.
