Power
supply
+10 V-GND
+10 V power
supply
Provides +10 V power supply to an external unit.
Its maximum output current is 10 mA.
Generally used to supply an external
potentiometer of 1 to 5 kΩ.
+24V-COM
+24 V power
supply
Provides +24 V power supply to an external
unit. Generally used for power supply for DI/DO
terminals and external sensors.
Maximum output current: 200 mA

.
OP
Input terminal
for external
power supply
Connected 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.
