Description

Emerson SE4308T01 – DeltaV IS 4-20 mA HART Analog Output CHARM

Product Overview

The Emerson SE4308T01 is an intrinsically safe analog output CHARM designed for Emerson DeltaV electronic marshalling systems. It provides a 4-20 mA analog output with HART communication capability, allowing control signals from the DeltaV system to be connected directly to field devices through an intrinsically safe I/O architecture. Emerson’s current DeltaV IS Electronic Marshalling documentation lists this model specifically as an IS AO 4-20 mA HART CHARM. The CHARM architecture allows I/O channels to be installed and assigned independently, reducing the need to redesign traditional I/O cabinets when field signal requirements change. This makes the part particularly useful for process control applications where analog valve, actuator, or other modulating-device signals must be handled within a hazardous-area compatible system.

Technical Specifications

Emerson’s official ordering information places this model alongside the SE4305T01 IS DI NAMUR, SE4306T01 IS DO 45 mA, SE4307T01 IS AI 4-20 mA HART, SE4309T01 IS Thermocouple/mV, and SE4310T01 IS RTD CHARMs.

Key Features and Benefits

• 4-20 mA analog output for continuous process-control signals.
• HART capability for compatible intelligent field devices.
• Intrinsically safe architecture for suitable hazardous-area applications.
• Designed specifically for DeltaV electronic marshalling.
• Supports distributed I/O design without conventional one-to-one cabinet wiring.
• Shares the standardized CHARM form factor with other DeltaV IS signal types.
• Useful for control valves, positioners, actuators, and other modulating final elements.

Personally, I would verify the hazardous-area certification and associated terminal-block assembly before replacing this module. Intrinsically safe I/O depends on the complete installation, not just the CHARM itself.

Installation and Maintenance

Install the module on the specified DeltaV CHARM baseplate and verify the associated intrinsically safe terminal-block arrangement before energization. Check channel identification, wiring polarity, grounding, and hazardous-area segregation against the approved system drawings.

During maintenance, inspect the CHARM housing, terminal connections, baseplate contacts, and diagnostic indicators. Do not interchange I/O types simply because they share the same mechanical form factor. The output type, IS characteristics, terminal assembly, and DeltaV configuration must all match the application.

Product Warranty

Warranty coverage depends on supplier, condition, and purchase agreement. Before procurement, confirm the exact model, condition, test status, revision where applicable, and warranty period. For critical DeltaV spares, retaining the original packaging and identification label can also help with future traceability.

The Emerson SE4308T01 is a specialized DeltaV IS analog-output component, and exact system compatibility should be confirmed before installation.
