ABB S900 AI930S 3KDE175511L9300 ATEX Zone 1 HART Module

Product Overview

The ABB AI930S (3KDE175511L9300) is a 4-channel analog input module from the ABB S900 I/O system, engineered for field installation in process automation and hazardous plant environments. Designed to interface directly with 4 to 20 mA field transmitters, the AI930S features full bi-directional HART protocol communication support, allowing seamless transfer of device configuration and diagnostic data between field instruments and the host system.

Certified with ATEX Zone 1 intrinsic safety protection, this compact module measures 20 mm x 104 mm x 104 mm and weighs only 0.14 kg. Built to endure harsh operating conditions, the AI930S features ISA-S71.04 G3 class conformal coating for superior resistance against corrosive atmospheres, alongside an extended operating temperature range of -20°C to +60°C and maximum relative humidity tolerance of up to 93% at 40°C.

Core Technical Advantages

• 4-Channel HART Communication: Transmits standard 4..20 mA process signals while providing direct HART digital pass-through for remote parameterization and asset health monitoring.
• ATEX Zone 1 Intrinsic Safety: Pre-certified for mounting and direct field-wiring in hazardous Zone 1 industrial areas without requiring additional barrier isolators.
• ISA-S71.04 G3 Corrosive Protection: Conformal-coated internal PCB surfaces protect against aggressive sulfur gas and industrial airborne contaminants.
• Compact Form Factor: Ultra-slim 20 mm module width maximizes channel density inside field termination enclosures.

Technical Specifications

Installation & Gap Calibration Guide

• Subrack Insertion: Slide the module into the designated S900 terminal unit slot until the locking lever securely clicks into place.
• Field Wiring Connection: Wire 4..20 mA HART transmitters to field terminal blocks, ensuring intrinsically safe separation rules for Zone 1 locations are maintained.
• Hot-Swapping Practice: Module supports hot-swap replacement under power in hazardous locations without interrupting neighboring S900 I/O channels.

Technical FAQs

Q1: What does model designation AI930S 3KDE175511L9300 indicate?
A1: ABB S900 4-channel 4..20mA analog input module with HART support and ATEX Zone 1 approval. (93 chars)

Q2: Does the AI930S support redundant configurations?
A2: No, this specific model is non-redundant. Dual-channel safety loop redundancy requires S900 S-series redundant racks. (100 chars)

Q3: What protection does the ISA-S71.04 G3 rating provide?
A3: It certifies the module against airborne corrosive gases like H2S and SO2 in harsh industrial plants. (96 chars)
