Power
supply
+10V-GND +10V-GND
Provide +10V power supply for external units,
with maximum output current of 10mA.
It is generally used as the operating power
supply for the external potentiometer. The
potentiometer resistance range is 1kΩ
to10kΩ.
+24V-COM
External
+24V power
supply
Provide +24V power supply for external units.
It is generally used as the operating power
supply for digital input/output terminal and the
external sensor.
The maximum output current is 200mA.
OP
Operating
power
terminal of IO
port
Prior to delivery, the OP is connected to
“+24V” with short circuit copper bar.
When it needs external power supply, OP
shall be connected with the external power
supply, and the short circuit copper bar shall
be removed.

1. Input voltage range: DC 0V to 10V/4mA to
20mA, which is determined by JK3 jumper on
the expansion card (the factory default value
is 0V to 10V).
2. Input impedance: It is 100kΩ at the time of
voltage input and 500Ω at the time of current
input.
