With the introduction of DeltaV SIS the left one-wide

and right one-wide dual carrier extenders have two,

44-pin D- Shell connectors which supports dual cables for

a fault tolerant configuration. The A and B connectors are

in parallel so either port may be used. The new dual carrier

extenders are a pre-requisite for DeltaV SIS as these also

provide extension of the redundant safety bus used by the

Safety Logic Solvers. The VerticalPLUS mount carriers also

support dual cables and can be used with DeltaV SIS.

Refer to the new VerticalPLUS Carrier Product Data Sheet

for more details on these new carriers.

The horizontal carrier family also offers a 2-wide power carrier.

Use this carrier, along with one or two system power supplies to

provide 12 V DC local bus power connected through the carrier

extenders. There are two 12 V DC output connections powered

by either supply. For redundant power, ensure that the power

demand is within the output range of one system power supply.
