Type
Terminal
Name
Function
output current 200mA. Cannot use for other ways, only for
X terminal power supply.
10V-GND
+10V power supply
Supply +10V power supply, max output current 20mA.
COM
Common terminal
of input X
When using the internal power supply to drive the X
terminal:
COM and 24V are short circuited to form NPN input;
COM and 0V are short circuited to form PNP input;
When using the external 24V power supply to drive the X
terminal:
COM is connected to external power supply 24V+,
disconnected from 24V of VH6 to form NPN input;
COM is connected to external power supply 0V,
disconnected from 0V of VH6 to form PNP input;
