2.3 Control Terminals and Connections
Type Terminal Terminal name Function description
+10V-GND 10V power supply
Provide 10V±10% power supply for
external-units, and the maximum output
current is 10mA.
It is generally used as the operating power
supply for the external potentiometer.
The potentiometer resistance range is 1
kȍ to 5kȍ.
+13V-GND
Pressure sensor
power supply
Provide 13V±10% power supply for
external units.
The maximum output current is 10mA.
It is generally used as the operating power
supply for pressure sensor.
+24V-COM
ˇ24V power
supply
Provide +24V power supply for external
units. It is generally used as the operating
power supply for digital input/output
terminals.
24V±10%, no-load virtual voltage can not
exceed 30V.
The maximum output current is 200mA. It
is internally insulated with GND.

COM and 24V is internally
insulated .Connect to 24V by default upon
delivery.
When external signal is used to drive
DI1toDI5, OP needs to connect to the
external power supply and disconnect
from the +24V power terminal.(It is
determined by the J7 jumper on the
control board.)
