Figure 1-7 G4 Ex Termination Board - ABB XSeries G4 6200 User Manual

1.2.3.1
The G4 EX termination board provides similar base I/O as earlier XSeries models
but with a reduced number due to enclosure restrictions. This includes:
-
-
-
-
1.2.3.2
The G4 EX provides one digital/pulse input as a means to monitor external
equipment.
The digital input reads an external contact. This is primarily used as a status input
to read external equipment. The contact must be closed to be considered "ON".
The "ON" condition is recorded in the log period alarms and can trigger the action
of the G4 EX's digital voltage output. OFF is defined as an open contact.
Selectable de-bounce can be enabled or disabled within PCCU32. See the
PCCU32 Help Files for additional information.
