Function Description
Power supply
+10V-GND
Ex10 V
power supply
P10 V power supply to
external unit.
Generally, it provides power supply to
external potentiometer with resistance
range of 1–5 kΩ.
Maximum output current: 10 mA
+24V-COM
Ex24V
power
supply Applying
to Overvoltage
Category II
circuit
P24 V power supply to
external unit.
Generally, it provides power supply to
DI/Do terminals and external sensors.
Maximum output current: 200 mA
PLC
Input terminal
of
external power
supply
Connect to +24 V by default.
When DI1-DI7 need to be driven by
external signal, PLC needs to be
connected to external power supply
and be disconnected from +24 V.
