The CIOC carrier is mounted to the top of a vertical DIN

rail and up to eight CHARM Baseplates are mounted below

it, snapping easily to the DIN rail as they are connected to

each other. The bus termination assembly is attached at the

bottom. A standard DIN-rail lock is used to keep the entire

assembly in place.

A pair of CIOCs installs on the carrier and communicates

over a redundant Ethernet network with up to four

controllers, allowing great flexibility and ease of system

expansion. Communication modules are available for

copper and fiberoptic media.

Each baseplate is ordered with 12 terminal blocks: standard

terminal blocks, fused injected power terminal blocks, or

relay output terminal blocks.
