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.

The Migration CIOC assembly has a height of 6 EIA units 

(10.5 inches) and is designed to be mounted at the top 

of the migration cabinet and connected to the CHARM 

baseplate assemblies through the cables and cable extenders. 

It should be noted that the CIOC can be mounted on vertical 

DIN-rail anywhere in the cabinet (front, back, side, top, 

middle, bottom) and connected to the CHARM baseplate 

assembly the same way. NOTE: the CIOC cannot be mounted 

on a horizontal DIN-rail.

The Migration CHARM baseplate assembly has a height of 

3 EIA units (5.25 inches) which allows for each installation 

to determine the mounting location within each cabinet. 

The user can decide to reuse existing wire way / cable tray, 

mount each assembly adjacent to each other, or mount with 

spacing between each assembly. DeltaV CHARMs allow for 

installation flexibility by allowing each assembly to be mounted 

as needed to achieve the best result for each customer-specific 

termination installation.

Each CHARM acts as a circuit protection device and field wiring 

disconnects. Signals are current limited or fused to protect 

against wiring faults to ground. Each CHARM provides surge 

protection to meet industry standards in the area of EMC, and is 

designed to fail during overvoltage conditions due to incorrect 

field wiring. Signal faults are isolated to the single CHARM.

CHARMs can be partially ejected to a locked position that 

disconnects the field wiring from the system to perform field 

maintenance actions or to remove power to a field device. 

Activating the CHARM latch ejects the CHARM to the detent 

position. Closing the latch locks the CHARM in place and 

isolates the field wiring for field work.

The CIOC communicates over Ethernet with up to four 

controllers, allowing great flexibility and ease of system 

expansion. Additional controllers can be added to 

accommodate increased control scope and I/O can be 

reassigned without changing the physical wiring. This allows 

you the flexibility required in migrations where over time 

I/O has been landed on one controller only to be used in 

another because of space and or available I/O.

CHARM Types

All CHARM types function on the migration panel. See DeltaV 

Electronic Marshalling PDS and DeltaV IS Electronic Marshalling 

PDS for a complete listing of CHARMs and IS CHARMs.

I/O Terminal Block Options

All IS and non IS I/O Terminal Block types function on the 

migration panel by choosing the right baseplate assembly.

CHARM Keying Posts

Keying Posts function the same.
