AI910N ABB S900 Analog Input Module 3KDE175513L9100

Product Overview

The AI910N is a 4-channel analog input module from the ABB S900 I/O series, designated under article number 3KDE175513L9100. It processes standard 4...20 mA loop-powered signals from 2-wire transmitters, offering dedicated field instrument data acquisition for non-hazardous industrial installations.

Key Advantages

• Loop-Powered Design: Suppresses external power wiring complexities by utilizing the instrumentation current loop.
• Environmental Protection: Certified under ISA-S71.04 G3 standards to survive highly corrosive and aggressive atmospheres.
• Slim Form Factor: The compact 20 mm width maximizes critical rail space inside control enclosures.

Technical Specifications

Quick Installation Tips

• Verify that the installation field remains designated as a safe, non-hazardous area prior to mounting.
• Confirm your loop instrumentation matches 2-wire architecture to leverage the module's passive line-powering structure.
• Maintain proper vertical ventilation spacing inside the cabinet to prevent thermal accumulation outside the -20°C to 60°C specification.

Technical FAQs

Q1: Does the AI910N support intrinsic safety for hazardous locations?

A1: No. This specific model features a non-intrinsically safe architecture and is built exclusively for use in safe, non-hazardous field areas.

Q2: What protection does the ISA-S71.04 G3 classification offer?

A2: The G3 compliance ensures the internal circuits are protected against severe corrosion caused by airborne contaminants like hydrogen sulfide and sulfur dioxide.

Q3: Does this module require an external voltage supply connection?

A3: No. The channel circuitry runs directly off the transmitter current loops, removing the need for auxiliary power line hookups.
