SS4301T02 Emerson IS DO 24VDC Low-Side CHARM | Original Spare Parts

SS4301T02 — Emerson DeltaV Intrinsically Safe Digital Output CHARM Module (IS DO 24VDC Low-Side)

The SS4301T02 is an Emerson DeltaV S-series CHARM (CHARacterization Module) designed for intrinsically safe 24 VDC digital output in hazardous-area process control environments. Engineered to meet the most demanding requirements of Industrial Automation and PLC System architectures, this module delivers reliable low-side (sinking) switching for field devices located in Zone 0 / NEC Class I Division 1 explosive atmospheres. As a 100% Brand New and Factory Sealed Original Spare Part, the SS4301T02 is sourced directly from Emerson’s authorized supply chain, ensuring full certification traceability and uncompromised performance in safety-critical Control Module applications.

Procurement managers and site specialists operating in Oil & Gas, Chemical Processing, and Power Plants consistently face the challenge of sourcing certified IS spare parts with short lead times. The SS4301T02 addresses this pain point by eliminating the need for external Zener barriers educing BOM complexity, cabinet footprint, and commissioning time. Its compatibility with the Emerson DeltaV S-series CHARM carrier (KL4210X1 / KL4220X1) makes it a drop-in replacement for legacy and active PLC System installations alike. Whether you are maintaining an existing SIS infrastructure or expanding a new Control Module network, this Original New component delivers the reliability your operation demands.

Backed by a 1-Year Warranty and fast global shipping, this module is the trusted choice for procurement teams who cannot afford downtime. Contact us today for pricing, datasheet, and lead time confirmation.

Technical Specifications & Selection Guide

Selection Tip: Verify field device entity parameters (Co, Lo) against module limits before installation. For high-side switching requirements, refer to the SE4302T01. For isolated output configurations, the SE4302T02 is the recommended alternative.

Core Features & Technical Advantages

• Barrier-Free IS Architecture: Eliminates external Zener barriers, cutting panel wiring by up to 50% and reducing cabinet space in hazardous-area PLC System installations.
• Precision Energy Limiting: Hardware current-limiting circuits cap output at 100 mA, keeping total circuit energy below the minimum ignition energy for Group IIC gases ven under dual-fault conditions.
• Hot-Swap Capability: Robust CHARM carrier interface supports live module replacement without system shutdown, minimizing process interruption during maintenance.
• Per-Channel Diagnostics: Eight dedicated status LEDs plus DeltaV software diagnostics detect open-circuit, short-circuit, and ground-fault conditions in real time.
• SIL 3 Capable: Systematic Capability (SC) 3 rating supports deployment in Safety Instrumented Systems (SIS) for ESD, F&G, and HIPPS applications.
• Wide Temperature Range: Heavy-duty design operates reliably from 40°C to +70°C, suitable for arctic offshore platforms and desert petrochemical sites alike.

Typical Application Scenarios

✅ Oil & Gas — Wellhead & Offshore Platforms: Zone 0 wellhead areas demand the highest level of intrinsic safety. The SS4301T02 directly drives IS-rated solenoid valves for emergency shutdown (ESD) and blowout prevention without external barriers, reducing offshore installation complexity and certification overhead.

Chemical & Petrochemical Processing: Reactor vessels and distillation columns operating with flammable solvents require IS-certified Control Module outputs. This module interfaces with agitator contactors, material addition valves, and reflux control solenoids inside Zone 0 classified areas, supporting continuous and batch process modes.

Power Plants — Turbine & Boiler Control: Precision digital output control for fuel gas isolation valves, burner management systems, and auxiliary equipment in classified areas of gas turbine enclosures. The module’s T4 temperature code and robust galvanic isolation ensure reliable operation in high-EMI power generation environments.

✅ Pharmaceutical Manufacturing: Solvent recovery and API synthesis areas classified as Zone 1/Division 1 benefit from the SS4301T02’s IS outputs for controlling vacuum isolation valves and solvent transfer pumps, with full DeltaV audit trail support for FDA 21 CFR Part 11 compliance.

✅ Grain & Agri-Processing: Combustible dust environments (Zone 20) in grain elevators and flour mills require T4-rated IS outputs for dust suppression nozzles and conveyor interlocks pplications where the SS4301T02’s energy-limiting design prevents ignition of fine particulate atmospheres.
