Product Overview

The Emerson SE4302T04 is a high-precision Digital Output (DO) CHARM Module designed for the DeltaV™ Distributed Control System (DCS). This module facilitates Electronic Marshalling, allowing for late-stage signal configuration and the elimination of traditional cross-wiring cabinets. It provides a controlled 24 VDC output specifically optimized for driving solenoid coils, interposing relays, and other binary actuators. By integrating intelligence at the individual channel level, the SE4302T04 simplifies project engineering, reduces cabinet footprints, and provides advanced diagnostics directly to the DeltaV control network.

Technical Specifications

The SE4302T04 incorporates energy-limited circuitry and robust isolation to maintain signal integrity in demanding process environments.

Engineering Advantages

• Electronic Marshalling Efficiency: The CHARM architecture allows any signal type to be landed on any terminal block. The SE4302T04 clicks into the CHARM I/O carrier, enabling software-defined characterization. This removes the need for complex internal wiring and massive marshalling racks, saving up to 50% in cabinet space.

• Advanced Line Fault Diagnostics: This module continuously monitors the health of the field wiring. It detects short circuits and open circuits in real-time without requiring external components. The 200 µs fault test timing ensures that operators receive immediate alerts for wiring failures before they impact process safety.

• Ruggedized for Harsh Environments: Emerson applies G3-level conformal coating to protect the SE4302T04 from airborne contaminants like hydrogen sulfide and chlorine. Combined with an operating range of –40 °C to +70 °C, this module thrives in remote field enclosures and offshore platforms.

• Intelligent Output Control: The module supports multiple configurable behaviors, including momentary output and continuous pulse output. Its 107 mA current-limiting feature protects the internal electronics and field wiring from overcurrent conditions, reducing the risk of fire or hardware damage in hazardous areas.

FAQs

Q: Is the Emerson SE4302T04 supplied as 100% Brand New?

A: Yes. We supply only 100% Brand New and Original Emerson hardware in factory-sealed packaging. Every SE4302T04 module includes a 12-month factory warranty to ensure long-term reliability in your DeltaV CHARM infrastructure.

Q: Can I replace this module while the system is live?

A: Yes. The SE4302T04 supports Hot-Swapping. You can remove and replace the module on the CHARM I/O carrier without interrupting the power or communication to other channels, facilitating rapid maintenance during continuous operations.

Q: What is the maximum load this CHARM can drive?

A: The module provides a continuous 100 mA at 24 VDC. This rating is specifically designed for standard industrial solenoid coils and high-efficiency relays. If your actuator exceeds this rating, you should use an interposing relay.

Q: Does the SE4302T04 require a specific terminal block?

A: The SE4302T04 installs onto the standard DeltaV CHARM I/O carrier. The specific terminal block used depends on your field wiring requirements (standard or fused), but the CHARM module itself performs the signal characterization and logic execution.
