Integrated power distribution. Controller and I/O interface

power distribution is integrated into the carriers to reduce and

simplify power and grounding. I/O Carriers have an integrated

shield ground bar to isolate and drain field noise away from

system power. They also provide an integrated redundant 24V

DC bussed field power distribution to reduce installation wiring

and provide fused, isolated power to each I/O interface, using

Power Buss Plugs. Alternatively, the I/O carriers can be ordered

with Power Terminal Plugs to bring dedicated power to each

card, which can be either 24V DC or 120/230V AC. Power Buss

Plugs and Power Terminal Plugs can be mixed on one

I/O Carrier.

A single Power Terminal Plug will come with any 120V AC DI

or 120/230V AC DO card.
