Installation notes
- The 8-Wide I/O Carrier installs on T-type DIN rails.
- Terminals on each end of the carrier provide separate field power for the odd and even numbered cards. When redundant cards are installed, the primary cards are powered from the left side connection and the secondary cards from the right side connection.
- Each card can be connected to the internal 24 VDC power bus through the fused plug installed in the socket above the card. To provide individually wired field power to each card, remove the fused plug and insert a terminal plug in its place. This is required for 120/230 VAC discrete cards.
- A shield ground bar to isolate and drain field noise away from the DeltaV system is integrated into the bottom of the carrier. The shield ground bar connection extends through the 8-Wide Carriers connected together on a single DIN rail. Connect only one ground wire for each group of 8-Wide Carriers on a DIN rail.
- For large systems in which 8-Wide I/O Carriers are installed on separate DIN rails, use the Left and Right Extenders to extend LocalBus and system power to carriers on those DIN rails.
- The 8-Wide I/O Carrier connects to adjacent carriers to form the LocalBus. Up to eight, 8-Wide Carriers can be connected together, along with the Power / Controller Carrier to form the LocalBus.
