Appendix A-3-2. VH6-B100 (Slot B IO card)
Overview
VH6-B100 is the expansion card of slot B, which can be used when the function or number of IO card of slot A
does not meet the field demand. It has 1 AI, 1 AO, 3 bipolar inputs, 1 YT and 1 YR.

Name
Function
Power supply
24V-0V
+24V power supply
Supply 24V power supply for input terminal X. max
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 50mA.
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;
