+
10V power supply
10V power supply, maximum output
current: 10mA
Generally it is used as power supply of external
potentiometer, potentiometer resistance range: 1kΩ
to 5kΩ
+24V-
COM
+24V power supply
24V power supply, generally it is used as
power supply of digital input and output terminals
and external sensor.
Maximum output current: 200mA
PLC
External power input
terminal
When external signal is used to drive, please unplug
PLC jumpers , PLC must be connected to external
power supply, and to +24V (default).
