Description

Product Overview

The GE DS3820LT4AIC1A is a high-performance LoadTrak IV Multi-Function Protection and Control Module designed for GE’s Mark IV Speedtronic turbine control systems. Engineered to integrate advanced motor protection, real-time monitoring, and configurable control logic, this module serves as a critical component in gas and steam turbine applications, ensuring reliable operation and safety in power generation, oil & gas, and heavy industrial environments.

 

As part of the Mark IV ecosystem, the DS3820LT4AIC1A processes analog and digital inputs from sensors (e.g., temperature, current, and speed) to execute protective actions and control commands. Its microprocessor-based architecture supports user-configurable trip parameters for overload, over-temperature, phase unbalance, and ground fault conditions910. The module interfaces with the Mark IV system via CAN Bus, enabling bidirectional communication for diagnostics, parameter adjustments, and data logging.

 

Featuring a front-panel LED display and push-button controls, the DS3820LT4AIC1A allows local configuration of motor protection settings and real-time status monitoring. Its rugged design withstands extreme temperatures (-20°C to +60°C) and electromagnetic interference (EMI), ensuring long-term stability in harsh industrial environments. By embedding this module into control architectures, operators gain actionable insights to optimize maintenance schedules and reduce unplanned outages, making it an indispensable asset in mission-critical systems.
