Emerson DeltaV™ VerticalPlus Input/Output Subsystem Carrier Description

Product Description

The VerticalPlus I/O Interface Carrier plugs into the 4-Wide Power/Controller Carrier,

which provides power to the system and communication between the I/O interface and the controller.

The controller processes I/O interface information through the control module.

The VerticalPlus I/O Interface Carrier provides a separate bus field power connection for each I/O card.

The carrier is designed to support the same terminals as the horizontal carrier.

The carriers are mounted on T-shaped DIN rails.

Each I/O interface carrier is supplied with connectors for direct mating together.

A single I/O subsystem supports a total of eight 8-width I/O interface carriers for a maximum of 64 local I/O interface cards.

Cable extenders are used to connect carriers that cannot be installed next to each other,

allowing the carriers to be arranged in standard equipment cabinets.

The extender has two 22-pin D-type connectors and supports a dual cable fault-tolerant configuration.

Ports A and B are connected in parallel so that either port can be used.

The new Dual Carrier Extender also supports the redundant secure bus coaxial connectors used by DeltaV SIS.

The total length of the I/O bus is 6.5 metres (21.3 feet).

The VerticalPlus carrier can also be used for Zone 2 remote I/O devices to provide installation flexibility.
