Description

Product Overview

The GE DS3820AISAIA1A is a high-performance Analog Input Module designed for GE’s Mark IV Speedtronic turbine control systems. Engineered to convert analog sensor signals into digital data for real-time system monitoring, this module supports seamless integration of temperature probes, pressure transmitters, and other analog devices in mission-critical industrial environments. As a core component of the Mark IV ecosystem, the DS3820AISAIA1A ensures reliable signal conditioning and noise filtering, making it ideal for gas/steam turbine control, oil & gas platforms, and heavy manufacturing applications.

 

Featuring 16-channel analog input capability, the DS3820AISAIA1A processes signals from 4-20mA current loops or ±10V voltage sources with 12-bit resolution. Its microprocessor-based architecture provides automatic zero and span calibration, ensuring accurate measurements even in high-vibration or EMI-prone settings. The module interfaces with the Mark IV backplane via a dedicated connector, eliminating the need for external signal converters and reducing cabling complexity.

 

Built with industrial-grade components, the DS3820AISAIA1A withstands extreme temperatures (-20°C to +60°C) and supports hot-swappable replacement without system shutdowns. Its front-panel LED indicators provide real-time status updates on power, channel activity, and error conditions, simplifying troubleshooting. By embedding this module into control architectures, operators gain actionable insights to optimize system performance and reduce unplanned downtime, making it an indispensable asset in high-reliability applications.
