Description

Product Overview

The GE DS3820AIQA is a high-reliability Analog Input/Output Module designed for GE’s Mark IV Speedtronic turbine control systems. Engineered to bridge analog sensor signals with digital control architectures, this module supports seamless integration of temperature, pressure, and vibration sensors while providing precision output control for actuators in mission-critical industrial environments. As a core component of the Mark IV ecosystem, the DS3820AIQA ensures robust signal conditioning and noise filtering, making it ideal for gas/steam turbine control, oil & gas platforms, and heavy manufacturing applications.

 

Featuring a hybrid analog-digital design, the DS3820AIQA processes 16-channel analog inputs (4-20mA/±10V) and 8-channel analog outputs (4-20mA) 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 26-pin connector, eliminating the need for external signal converters and reducing cabling complexity.

 

Constructed with industrial-grade components, the DS3820AIQA 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.
