Description

Product Overview

The ABB AI950S (3KDE175521L9500) is an intrinsically safe, 4-channel analog input module designed for the ABB Advant S900 automation control system. Engineered for critical industrial and hazardous area applications, it supports a wide array of temperature and electrical signal inputs including Thermocouple, RTD, mV, and Resistance. Operating on a 24V DC power supply with a lightweight net weight of approximately 0.25 kg (0.55 lbs), the AI950S features integrated HART communication, 500V DC channel isolation, and power/communication redundancy. Built with robust auto-diagnostics and IP20 protection, it delivers accurate data processing across extreme operating temperatures ranging from -40°C to +70°C.

Key Advantages

  • Intrinsically Safe Design: Built for reliable sensor signal acquisition in hazardous process environments.
  • Compact & Lightweight: Net weight of approximately 0.25 kg for easy, high-density I/O station mounting in tight enclosures.
  • Multi-Signal Versatility: Direct interface support for Thermocouples, RTDs, millivolt (mV), and resistance inputs with high 10MΩ input resistance.
  • HART & Extended Diagnostics: Integrated HART protocol support with advanced auto-diagnostics for real-time field device telemetry.
  • Extreme Thermal Endurance: Operates continuously across an extended temperature range from -40°C up to +70°C.
  • Redundant Architecture: Equipped with power and communication redundancy combined with 500V DC channel-to-channel isolation.
