Description
GE IC3600LRDC1: Logic Relay Driver Board for Mark I/II Turbine Control Systems
Product Overview
The GE IC3600LRDC1 is a high-performance logic relay driver board engineered for GE’s Speedtronic Mark I/II turbine control systems, specializing in converting low-level control signals into high-power outputs to drive electromagnetic relays in industrial automation environments. As part of the IC3600 series, this module plays a critical role in managing sequential logic operations, safety interlocks, and field device actuation within gas and steam turbine applications .
Key to its functionality is the dual-channel relay drive architecture, which integrates 32 transistors (arranged in two rows of 16) and 16 diodes to provide 500mA per channel sinking/sourcing capability. The GE IC3600LRDC1 features a rugged PCB design with gold-plated connectors and two aluminum electrolytic capacitors, ensuring stable performance in extreme temperatures (-40°C to +85°C) and high-vibration settings. By interfacing with Mark I/II backplanes, it supports real-time control of fuel valves, solenoids, and motor starters, enhancing system reliability and reducing downtime .
While the GE IC3600LRDC1 is a legacy component, refurbished units undergo rigorous thermal cycling and signal integrity tests to meet OEM standards, making it a cost-effective solution for maintaining critical infrastructure. Its modular design allows seamless integration with other Mark I/II modules like power supply cards and analog-to-digital converters, extending the operational lifespan of legacy control systems .
