DeltaV Product Data Sheet
October 2014 – Page 4 S-Series Electronic Marshalling
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 CIOC’s can be added
online.
CHARM Types
A variety of analog and discrete CHARMs are available to
meet your specific requirements. The following CHARMs
are available starting with v11.3.1:
AI 4-20 mA HART
RTD
Thermocouple / mV
AI 0-10 VDC Isolated
AO 4-20 mA HART
DI NAMUR
DI 24 VDC low-side sense (dry contact)
DI 24 VDC Isolated
DO 24 VDC High Side
DO 100mA Energy Limited
DO 24 VDC Isolated
24 VDC Power
DI 120 VAC Isolated
DI 120 VAC Isolated Plus
DI 230 VAC Isolated
DO VAC Isolated
All CHARMs have a bi-color Power/Integrity LED that
indicates the health of the CHARM. The indications
provide clear, actionable instruction to the maintenance
personnel.
Green Solid: Normal Operation
Green Blink: Normal awaiting configuration
Red Blink: Fault detected on wiring
Red Solid: Internal Fault detected
Discrete CHARMs have a Yellow LED to indicate the state
of the field signal. (On = circuit is energized)
All CHARMs meet ISA 71.04-1985 severity level G3
(harsh) corrosion specifications.
24 VDC based discrete input CHARMs support pulse
counters with a maximum frequency of 10 KHz.
I/O Terminal Block Options
There are 5 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
The Standard Terminal block can be used with all
CHARMs types. For traditional wiring of field
instrumentation, the CHARMs provide loop power through
the internally distributed 24 VDC field power. Refer to
specific CHARM specifications for wiring information.
Both, the Fused Injected Power Terminal block as well
the 3-wire DI Fused Injected Power 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, creating a system
powered circuit that can deliver up to 1 amp (DC) of power
on discrete output channels. Each baseplate has a local
power bus that can be connected to 24 VDC or 120/230
VAC through the injected power input terminals, located
on the Address Plug terminal block. Both, the Fused
Injected power Terminal Block and the 3-wire DI Fused
Injected power 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.
The Relay Output Terminal Block is designed for high
output current applications and requires the DO 24 VDC
High-side CHARM to drive the relay coil. The Relay
Output Term blocks provide a normally open and normally
closed contact with the following ratings:
