Get your I/O subsystem up and running efficiently with the DeltaV™ horizontal mount I/O carriers. The power/controller carrier contains internal power buses. You don’t need to use external cabling to connect the system power supply to the DeltaV controller and the I/O interface carriers. The power/controller and I/O carriers are modular. Purchase only what you need but be assured that as your system grows you can add plug-and-play carriers—Easy!

Benefits

Modular design allows flexible installation. A T- type DIN rail is all you need to mount the power/controller carrier into place. The I/O interface carrier plugs on to the power/controller carrier. Simply plug your I/O terminal blocks into the carrier. The DeltaV system’s modular design approach allows you to add I/O carriers as you need them.

Allows you to expand online. Additional 8-wide carriers may be added online as desired. Carrier extenders give you the flexibility to install I/O carriers in multiple rows with 1,2, 3 or 4 carriers per row.

Integrated power distribution. Controller and I/O interface power distribution is integrated into the carriers to reduce and simplify power and grounding. Carriers also have integrated shield ground bar to isolate and drain field noise away from system power.

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.
