Control terminals&functions

CategoryTerminal symbolTerminal nameFunction description
Power supply+10V-GND+10V power supply

Provide +10V power supply to external unit.

Generally, it provides power supply to external potentiometer with resistance range of 1-5 kΩ.

Maximum output current: 20 mA

+24V-COM+24V power supply

Provide +24V power supply to external unit.

Generally, it provides power supply to DI/DO terminals and external sensors. Maximum output current: 150 mA

OPExternal power input terminal

Connect to +24V by default.

When DI1-DI6 need to be driven by extemal signal, OP needs to be connected to external power supply and be disconnected from +24V.
