Technical specifications for SS4303T01

Description

Emerson SS4303T01 LS AI 4-20 mA HART CHARM

DeltaV SIS™ Electronic Marshalling
Hardware Includes:
„ CHARM Smart Logic Solver Carrier (DIN rail mounted and
supports a redundant pair of CHARM Smart Logic Solvers,
redundant 24V DC power connectivity, and redundant
Ethernet Safety Network communication Ports).
„ CHARM Smart Logic Solver (provides redundant
safety logic processing and communication to up to
96 LS-CHARMs).
„ CHARM Base plate (DIN rail mounted with interleaving
power and bus connectors. Supports 12 LS CHARMS and
their terminal blocks, as well as connection for injected
field power).

LS CHARM Terminal Block (removable terminal block
providing terminal connections to field wiring and
physical latch for LS-CHARM).
„ LS CHARMs (Logic Solver Characterization Module for
each field signal. Provides basic characterization and
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 base plate and
channel identification.
The CHARM Smart Logic Solver carrier is mounted to the
top of a vertical DIN rail and up to eight CHARM Base plates
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 CHARM Smart Logic solvers install on the carrier
and communicate over a redundant Ethernet safety
network with up to 15 other CSLSs and 1 SZ controller,
allowing great flexibility and ease of system expansion.
SNPs are available for copper only.
SZ controllers connect to both the area control network
and the LSN to isolate the CSLSs from the process control
system. The SZ controllers has replaceable Ethernet
Isolation Ports for connection to both LSN and the DeltaV
Area Control network. Starting in DeltaV v14.3 a new
Keylock Ethernet Isolation Port, in yellow color plastic,
which enable the key inhibit unlock switch on the carrier to
allow the key to inhibit the unlock command to all CSLSs on
the LSN.
Only DeltaV SIS Smart Switches are supported on the Local
Safety Network (LAN).
Each baseplate is ordered with 12 terminal blocks: standard
terminal blocks or fused, injected power 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 LS CHARM to complete the
field circuit and the signal is ready to be used by the CSLS.
No cross-wiring required.
Each LS CHARM acts as a circuit protection device and field
wiring disconnect. Signals are inherently current limited
to protect against wiring faults to ground. Each LS CHARM
provides surge protection to meet industry standards in the
area of EMC. Under extreme overvoltage conditions due
to incorrect field wiring, the LS CHARM will act as a fuse to
protect adjacent channels. Signal faults are thus isolated to
the single LS CHARM.
LS 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 LS CHARM latch ejects the LS CHARM
to the detent position. Closing the latch locks the LS CHARM
in place and isolates the field wiring for field work.
Baseplate extenders and cables provide great flexibility to
the LS CHARM installation in existing cabinets or in custom
enclosures. Cables are redundant, each carrying 24V DC
field power, 6.3V DC LS-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.
LS CHARMs can be added to any existing base plate
position and autosensed online. Additional CSLS can be
added online.
