3.4 Control terminal and function

Category Terminal Symbol Terminal Name Function Description
Power +10V-GND +10V Power Provides +10V power externally, maximum output current: 20mA, typically used as the operating power supply for external potentiometers
Power +24V-COM +24V Power Provides +24V power externally, maximum output current: 150mA, generally used as the power supply for digital input-output terminals and external sensor power
Power OP External Power Input Terminal Connects to +24V or COM through the connection piece on the control board (factory default connection to +24V)
When driving DI1~DI6 with external signals, OP needs to be connected to an external power source, and the short-circuit connection piece between OP and 24V should be removed
