3KDE175513L9310 AI931N ABB S900 4-Channel Analog Module

Technical Specifications

Product Overview

The ABB 3KDE175513L9310 AI931N is a compact 4-channel analog input module designed for the ABB S900 remote I/O system. Weighing just 0.125 kg and measuring 20 mm in width, this module processes 4...20 mA signals from passive field loops and supports cyclic HART data exchange. Built for demanding industrial environments, it features ISA-S71.04 G3 harsh environment certification and simplified wiring with shared returns to ensure reliable process monitoring.

Key Features

• HART Communication Support: Enables cyclic data exchange with smart field instrumentation over 4...20 mA analog signals.
• G3 Harsh Environment Protection: ISA-S71.04 G3 conformal coating protects internal circuitry from corrosive gases and chemical atmospheric hazards.
• Optimized Compact Form Factor: Ultra-slim 20 mm width allows high-density cabinet mounting to minimize space requirements.
• Simplified Field Wiring: Designed with shared returns across all four input channels for efficient cabinet installation.

Installation Essentials

Snap the AI931N module directly onto its designated S900 terminal unit inside a ventilated control enclosure. Ensure field wiring follows passive 4...20 mA loop practices using the shared return setup. Confirm operating ambient temperatures remain within the -20°C to +60°C range and relative humidity does not exceed 93% at 40°C.

Technical FAQs

Q1: Does the ABB AI931N 3KDE175513L9310 module support HART protocol?
A1: Yes, the module fully supports cyclic HART data exchange over standard 4...20 mA analog input channels.

Q2: Is this module suitable for intrinsically safe (Ex) applications?
A2: No, the AI931N model does not support intrinsic safety; it is designed for standard non-Ex industrial environments.

Q3: What environmental protection rating does the AI931N carry?
A3: It is ISA-S71.04 G3 certified to resist corrosive atmospheric conditions and operates in temperatures from -20°C to +60°C.
