The Fused-Injected-Power Terminal block, the 3-wire

DI Fused-Injected-Power Terminal block, and the 3-wire

AI Fused Injected Terminal block includes a 2A field

replaceable fuse. The 3-wire DI Fused-Injected-Power

Terminal block is designed to be used with all isolated

discrete Input CHARM types, while the Fused Injected

Power Terminal block is designed to work with all Isolated

discrete Output CHARM types, the 3-wire AI Fused

Injected Power Terminal block is used with AI 4-20mA

HART CHARM type creating a system-powered circuit that

can deliver up to 1 amp (DC) to the field.

Each baseplate has a local power bus that can be

connected to 24V DC or 120/230V AC through the injected

power input terminals, located on the Address Plug

terminal block. Both, the fused-injected power Terminal

Block, the 3-wire DI fused- injected power Terminal Block,

and the 3-wire AI Fused Injected Terminal block connect to

this power bus to provide system power to the field circuit

through the isolated CHARM. You can combine isolated and

system powered circuits on the same baseplate, however, all

system powered channels on a baseplate share the same power source.

I/O Terminal Block Options

• There are six different I/O terminal blocks available to

meet the wiring needs of field signals

• Standard Terminal Block

• Fused-Injected-Power Terminal Block

• 3-wire DI Fused Injected-Power Terminal Block

• Relay Output Terminal Block

• Thermocouple / mV Terminal Block

• 3-wire AI Fused Injected Power Terminal Block

The Standard Terminal block can be used with all CHARM

types. For traditional wiring of field instrumentation,

the CHARMs provide loop power through the internally

distributed 24V DC field power. Refer to specific CHARM

specifications for wiring information.

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.

Baseplate extenders and cables provide great flexibility to

the CHARM installation in existing cabinets or in custom

enclosures. Cables are redundant, each carrying 24V

DC field power, 6.3V DC CHARM power, and one of the

communication busses.

Bus termination provides added robustness for the

communication bus and is installed at the end of the

physical bus.

Label features are available to identify channel usage and

Baseplate identification to help with maintenance.

CHARMs can be added to any existing baseplate

position and autosensed online. Additional CIOCs can be

added online.

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.

Electronic Marshalling eliminates the need to partition the

I/O wiring to specific channels based on signal type. Simply

connect field signal multi-cores in an orderly fashion as

desired. Install the appropriate CHARM to complete the

field circuit and the signal is ready to be used by any one of

four controllers. No cross-wiring required.

Each CHARM acts as a circuit protection device and field

wiring disconnect. Signals are inherently current-limited

to protect against wiring faults to ground. Each CHARM

provides surge protection to meet industry standards in

the area of EMC. Under extreme overvoltage conditions

due to incorrect field wiring, the CHARM will act as a fuse to

protect adjacent channels. Signal faults are thus isolated to

the single CHARM.

Product Description

Electronic Marshalling hardware includes:

• CHARM I/O Carrier (DIN rail-mounted and supports

redundant pair of CHARM I/O Cards, redundant 24

V DC power connectivity, and redundant Ethernet

communication modules).

• CHARM I/O Card (CIOC) provides communication

between CHARMs and the Ethernet I/O network to

M-series, S-series, and PK Controllers. The CIOC has

Achilles Communications Certification Level 1 and the

redesigned CIOC2 has more computing power and

Achilles Communications Certification Level 2. The CIOC2

is a drop-in replacement for the CIOC (v13.3.1 or later

is required).

• CHARM Base plate (DIN rail-mounted with interleaving

power and bus connectors. Supports 12 CHARMs and

their terminal blocks, as well as connection for injected

field power).

• CHARM Terminal Block (removable terminal block

providing terminal connections to field wiring and

physical latch for CHARM).

• CHARMs (Characterization Module for each field signal.

Provides basic analog to digital conversion and signal

isolation to the redundant communication bus).

• Cable Extenders that provide flexibility in

carrier mounting.

• I/O bus termination (provides bus terminations for

redundant I/O bus).

• Labeling features for baseplate and channel identification.

Complete DeltaV solution: Migrate from your legacy system

with the comfort that when complete you will have a complete

DeltaV solution, not a combination of standard and custom

hardware/software to support. Every piece of the migration

panel is standard DeltaV hardware and can be supported with

the same personnel and spare equipment that every other

CHARMs and DeltaV installation uses.

Plug and play I/O: The DeltaV CIOC has been designed for

ease of use, both in physical installation and its software tools.

Components snap together with secure DIN-rail latches and

interlocking carrier connectors. Insert the CHARMs and auto

sense the node to create the I/O definition automatically in

your DeltaV configuration database. CHARMs use a self-keying

system to automatically set a channel for a specific CHARM

type. Users cannot mistakenly insert a CHARM into the wrong

terminal block. Assign all, one, or any number of channels to a

controller with a simple click and drag.

Replaces legacy I/O in place: DeltaV Electronic Marshalling

goes where no one else’s I/O can. Install the CHARMs migration

panel above, below, or even in front of your legacy termination

panel and move your wires inches to complete your migration

to DeltaV. Since the CHARMs migration panel is a standard

CHARMs baseplate, it talks to the CIOC the same as the

standard vertical installation through the cable interface.

This allows you to mount the migration panel in the best

location to facilitate a clean system cutover and not have to

“stretch” your I/O cables to a new termination. As an added

bonus, install CHARMs vertical if your wiring allows for it in

certain areas. Now you can mount your I/O in any orientation

as best fits your current migration layout and needs.

Fully redundant communications: The CIOC architecture is

fully redundant. This starts with the two I/O cards on a carrier.

The carrier has redundant communication modules for primary

and secondary network connections. There are two 24 V DC

input power connections. The carrier connects to the CHARMs

Baseplates and provides redundant power and communication

buses to the CHARMs. Everything is redundant down to the

individual channel.

Benefits

I/O anywhere you need it: The DeltaV CIOC provides

unprecedented flexibility in control system I/O topology.

Now you can mount your DeltaV I/O in the same space as your

legacy I/O for a direct 1-to-1 replacement. Without adding

any new cabinets of DeltaV hardware you can replace all your

legacy equipment leaving behind a complete DeltaV solution.

Single Channel granularity: The CHARM I/O architecture

allows each individual channel to be characterized for the

requirements of the field device. Any instrument signal can be

wired to any terminal block. The channel is then electronically

marshalled by installing the appropriate CHARM and assigning

the channel to one of four controllers. Legacy I/O terminations

are no longer a concern because of multiple channel types

from a single termination panel. Just install the proper CHARM

to characterize the I/O as found on the legacy panels. No more

engineering and splitting signals from a single legacy panel to

multiple DeltaV I/O cards

System Compatibility

M-series, S-series and SZ controllers are all supported on

DeltaV v12.3 and beyond. PK Controllers are supported on

DeltaV v14.3 and beyond. For detailed version compatibility

see the Prerequisites section below.

Redundant controller pairs must be of the same series. For

example, M-series and S-series controllers cannot be connected

together as a redundant pair.

Although an SX controller can operate as a standby controller to an

SQ active controller, it is recommended that both the active and

standby controllers be of the same hardware. The SQ may not have

sufficient memory or CPU capacity to accept the configuration that

runs in an SX controller. This applies for MX and MQ controllers as

well, only mix controller types as a temporary condition during a

hardware upgrade.

The MQ, MX, SQ, SX and PK Controllers are all capable of

redundancy. For more information on these controllers, refer to

the respective controller product data sheet.

SZ Controllers are also capable of redundancy. For more

information on this controller, refer to the DeltaV SIS Electronic

Marshalling or DeltaV SIS IS Electronic Marshalling product data sheets.
