Overview

The ABB 216GD61A (HESG324436M1/A) is an analog input module designed for ABB’s distributed control systems (DCS), including the Symphony and Advant Master series. It acquires and digitizes analog signals from field instruments such as pressure transmitters, temperature sensors, and flow meters.

The module supports multiple input types—including voltage, current, thermocouple, and RTD signals—and offers high-resolution A/D conversion for accurate data acquisition. It also provides galvanic isolation between channels and the system bus, ensuring signal integrity and operational safety.

For example, in a thermal power plant, the 216GD61A can monitor boiler temperature and pressure in real time, enabling optimized combustion control and safe operation.

Technical Data

Typical Applications

• Power Generation: Monitors turbines, boilers, and auxiliary systems.

• Petrochemical Plants: Acquires data from pressure, temperature, and flow sensors.

• Water & Wastewater Treatment: Tracks pH, turbidity, and flow for process optimization.

• Industrial Automation: Integrates with PLCs and DCS for real-time monitoring and control.

• Renewable Energy Systems: Captures analog data from solar inverters and wind turbines.

The 216GD61A is also frequently used in system upgrades, replacing legacy analog modules with modern, high-resolution alternatives.
