Emerson CE4005S2B4
Product Name
Emerson CE4005S2B4 DeltaV Compact CHARM I/O communication module, commonly configured for analog input characterization.
Product Introduction
CE4005S2B4 is documented in supplier and project data as a DeltaV Compact CHARM interface and I/O communication module. It provides intelligent signal characterization, isolation, and HART-enabled analog input processing for DeltaV control and safety architectures.
Detailed content
Technical Specifications
Configured analog input channels support 4 to 20 mA, 0 to 20 mA, 0 to 10 V, and ±10 V depending on CHARM frontend. Resolution is 16 bits. Typical accuracy is ±0.1% of full scale. Data refresh for the documented channel set is within 100 ms. Communication uses DeltaV native protocol with HART through CHARM frontends. Module power is supplied from the DeltaV Compact backplane at 24 VDC. Operating temperature is -20 to 65°C. Storage temperature is -40 to 85°C. Relative humidity is 5 to 95% noncondensing.
Function Features
Per-channel signal-type configuration, HART communication, open-circuit and short-circuit diagnostics, overrange and underrange detection, hot-swap support on compatible carriers, and electrical isolation between field and system.
Application Scenarios
DeltaV process control, intelligent transmitter interfacing, safety-instrumented analog acquisition where qualified, pharmaceutical and chemical batch systems, and remote I/O rooms requiring digital CHARM signal transport.
Performance Parameters
Sixteen-bit conversion provides fine resolution for 4 to 20 mA and voltage signals. HART digital communication operates alongside analog measurement for device diagnostics. Diagnostic alarms report channel faults to DeltaV workstation software.
Material Composition
Industrial PCB with signal-conditioning ASICs or discrete instrumentation amplifiers, CHARM connector interface, isolation barriers, and flame-retardant module housing.
Structure Features
Compact CHARM module format for DeltaV Compact carrier or CHARM bank. Field-side CHARM frontend performs isolation and conversion; backplane side transfers digital measurement data. Status indicators are provided according to carrier design.
Working Principle
The field transmitter signal is conditioned by the CHARM frontend, converted to digital values, isolated from the control system, and transmitted over the DeltaV Compact backplane. The CPU or controller reads characterized values, executes control logic, and returns HART commands to the field device when HART is enabled.
Installation Requirements
Install in the designated DeltaV Compact carrier or CHARM mounting assembly. Use shielded field cables grounded according to DeltaV installation practice. Confirm backplane 24 VDC and CHARM compatibility before insertion.
Usage Notes
Verify each channel signal type, range, and HART option in DeltaV configuration. Do not mix incompatible CHARM frontend types in one bank without engineering validation. Perform periodic diagnostic review for open, short, and overrange conditions.
