The following figure shows the terminal connections for connecting bussed field power to the 4-Wide I/O Carrier. Note that the positions of the supply and supply return terminals differ from those of the DeltaV I/O carriers.

Note

When a 4-Wide Horizontal I/O Interface Carrier is used with an M-series controller or Remote Interface Unit, DeltaV software displays four additional blank I/O slots that do not exist. For example, if a 4-Wide Horizontal I/O Interface Carrier is installed to the right of the first 8-Wide I/O Interface Carrier in the I/O subsystem, DeltaV software displays I/O Slots 9-12 and blank I/O Slots 13-16. If another carrier is installed to the right of the 4-Wide Horizontal I/O Interface Carrier, the first slot of that carrier is I/O Slot 17. This behavior does not occur when the carrier is used with a PK Controller.
