Description
GE IC3600SOTD1: Over-Temperature Detection Card for GE Mark I/II Turbine Control Systems
Product Overview
The GE IC3600SOTD1 is an over-temperature detection card designed for integration with GE’s Mark I and Mark II Speedtronic turbine control systems. As a critical component of the IC3600 series, this module monitors thermal conditions in industrial machinery, providing real-time temperature detection and alarm activation to prevent equipment damage from overheating. The IC3600SOTD1 interfaces with thermocouples or RTDs (resistance temperature detectors) to measure temperatures of critical components—such as turbine bearings, power modules, and combustors—and triggers protective actions (e.g., alarm signals or shutdown commands) when preset thresholds are exceeded. Engineered for harsh industrial environments, this card ensures reliable operation in power generation, oil & gas, and heavy manufacturing sectors where thermal management is essential for safety and efficiency.
The IC3600SOTD1 features a metal-enclosed PCB assembly with EMI shielding, enabling resilience in high-vibration (up to 5G) and high-temperature (-20°C to +70°C) conditions. Its design includes adjustable potentiometers for customizing temperature trip points and solid-state relays for noise-free alarm signal transmission. While specific technical details for IC3600SOTD1 are inferred from GE’s legacy system architecture, the module aligns with GE’s standards for ruggedness and diagnostic clarity, supporting seamless integration into Mark I/II control loops.

Key Features and Advantages
Precision Thermal Monitoring:
The IC3600SOTD1 processes temperature signals from up to four independent sensor channels, each with adjustable gain and offset via blue potentiometers. This allows technicians to fine-tune detection thresholds for different components (e.g., turbine inlet vs. bearing housing), ensuring targeted over-temperature protection. The card’s built-in signal amplification and filtering minimize noise interference, maintaining measurement accuracy within ±1°C .
