Emerson DeltaV™ M-series I/O carriers System Compatibility

System Compatibility

M-series I/O carriers are not physically compatible with

S-series controller carriers, except when used with the

DeltaV SIS Adapter.

The M-series controllers cannot detect the difference between

an 8-wide and a 4-wide carrier. If a 4-wide carrier is used,

the four I/O slots after the slots on the carrier will be lost to

an M-series controller. If either a 4-wide or 8 wide carrier is

connected after a 4-wide carrier, the first slot number will

be 5 numbers higher than the last slot on the 4-wide carrier.

For example, if a controller has a 4-wide carrier followed by

an 8-wide carrier, the slots on the 4-wide carrier will be

1. 2. 3. and 4. and the slots on the 8-wide carrier will be

slots 9. 10. 11. 12. 13. 14. 15. 16. The PK Controller does

not have this behavior because it can distinguish between

a 4-wide and an 8-wide carrier. However, there is still a limit

of 8 total carriers (4-wides and/or 8-wides) on any controller.

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.

With the introduction of the PK controller, a 4 wide I/O carrier

is available for use with M-series I/O cards when a smaller

footprint for the hardware is required. The 4-wide carrier

allows for individual field power per card slot and is ideal

if separate field power is required for redundant I/O cards.
