ABB IMASM03 | INFI 90 Analog Input Slave Module

Product Description

The IMASM03 Analog Input Slave Module (ABB Bailey) is engineered for reliable and precise analog signal acquisition within ABB’s INFI 90 Distributed Control System (DCS). It converts field device outputs—including current, voltage, RTD, and thermocouple signals—into digital data for real-time process monitoring and control. Optimized for continuous industrial operation, this module is suitable for power generation, chemical plants, water treatment, and similar automated environments.

Key Features:

• High-precision 12-bit analog-to-digital conversion

• Supports multiple analog input types: 4–20 mA, 0–10 V, RTD, thermocouples

• 8 independent input channels for versatile sensor integration

• Advanced diagnostics for fault detection and configurable inputs

• Compact, robust housing designed for harsh industrial conditions

Technical Specifications:

Applications:

• Power Plants: Monitor temperature, flow, and pressure from multiple sensors

• Chemical Processing: Accurate analog data acquisition for process control

• Water & Wastewater Treatment: Reliable input from flow and level sensors

• Oil & Gas Facilities: Robust module performance in harsh environments

FAQ:

Q: Can this module handle thermocouples?
A: Yes, it supports various thermocouple types along with RTDs, 4–20 mA, and 0–10 V signals.

Q: Is the module compatible with all ABB DCS systems?
A: It is designed specifically for ABB Bailey INFI 90 systems. For newer DCS series, modernization may be required.

Q: What is the difference between IMASM03 and IMASM02?
A: IMASM03 adds more advanced diagnostics and supports additional signal types, whereas IMASM02 is primarily a standard analog input module.
