The functions of the terminals of the control circuit are described as follows:
Table 3-4 Description of functions of the control circuit terminals
Type Terminal Name Function Description
Power
supply
+10V-GND
External +10 V power
supply
Provides a +10 V power supply to an external unit
Generally used to supply an external potentiometer of 1 to 5 kΩ
Max. output current: 10 mA
+24V-COM
External +24V power
supply
Provides a +24V power supply to an external unit
Generally used to supply the DI/DO terminals and external
sensors
Max. output current: 200mA
OP
Input terminals of
external power supply
Connect to +24 V by default
When DI1 to DI5 need to be driven by external signals, OP
must be disconnected from +24 V and connected to an external
power supply.
