• CHARMs (Characterization Module for each field signal.
Provides basic analog to digital conversion, connectivity
to redundant communication bus, and fault isolation).
• Cable Extenders that provide flexibility in carrier mounting.
• Baseplate terminators (provides bus terminations for
redundant I/O bus).
• 19” Migration Panels (provides DIN-rail mounting for two
migration CIOC’s or two baseplates and cable extenders
for installation into your standard 19” legacy cabinets).

The CHARM I/O card carrier is supposed to be mounted
on a vertical DIN-rail and can communicate with up to
eight CHARM Baseplates mounted vertically or on migration
panels and connected to each other through extender cables.
The bus terminators are attached to the last baseplate.
Each CHARMs Migration Baseplate Assembly is
ordered pre-loaded with 24 terminal blocks that are
ready to receive field wires from 2-, 3- , and 4-wire devices.
Electronic Marshalling eliminates the need to scramble the
field wiring or to partition the I/O to match signals to channel
types of specific cards. Simply connect field signals in an orderly
fashion as desired. Insert the appropriate CHARM into each
terminal block to complete the field circuit and the signal
is ready to be used by any, up to four controllers.
For each Migration CIOC installation you will need to
determine the quantity and connector cable length as
well as the appropriate quantity of top and/or bottom
baseplate terminators.
