Description
GE IC3600LIVD1A: Logic Inverter Circuit Board for Mark I/II Turbine Control Systems
Product Overview
The GE IC3600LIVD1A is a high-reliability logic inverter circuit board designed for GE’s Speedtronic Mark I/II turbine control systems, specializing in signal inversion and digital logic operations within industrial automation environments. As part of the IC3600 series, this module plays a critical role in converting and conditioning binary signals, enabling precise control of turbine speed regulation, fuel distribution, and safety interlocks in gas and steam turbine applications 36.
Key to its functionality is the dual-channel logic inversion circuit, which integrates seventeen polyester vinyl capacitors (sixteen marked “C1” with 0.001μF ±10% 200V rating and one marked “C2” with 0.047μF ±10% 200VDC rating), sixteen transistors (marked “Q1”), and eighty carbon composite resistors (grouped as R1–R5) to ensure stable signal integrity 36. The GE IC3600LIVD1A features a rugged PCB design with gold-plated 51-pin connectors and a metal enclosure, supporting operation in extreme temperatures (-40°C to +85°C) and high-vibration settings. By interfacing with Mark I/II backplanes, it facilitates real-time control of turbine auxiliary systems, such as anti-surge valves and lubrication pumps 310.
While the GE IC3600LIVD1A is a discontinued product, refurbished units undergo rigorous thermal cycling and signal integrity tests to meet OEM standards, making it a cost-effective solution for maintaining legacy systems. Its modular design allows seamless integration with other Mark I/II modules like logic binary boards and relay driver cards, extending the operational lifespan of critical infrastructure 69.

Installation and Maintenance
Installation Preparation:
- Power Down: Ensure the control system is de-energized and grounded to prevent electrostatic discharge (ESD) damage. Verify backplane compatibility with Mark I/II Type 3 or 4 versions 310.
- Physical Mounting: Secure the GE IC3600LIVD1A on a DIN rail or backplane, following GE’s wiring diagrams for pin assignments. Use shielded cables for analog inputs/outputs to reduce electromagnetic interference 69.
- Component Check: Inspect the board for physical damage, such as bent pins or swollen capacitors, before installation 3.
Maintenance Recommendations:
- Quarterly Inspections: Check for swollen capacitors, loose solder joints, or discolored resistors. Replace electrolytic capacitors (e.g., aluminum units) if bulging or leaking 69.
- Annual Calibration: Validate voltage scaling accuracy using a precision multimeter, adjusting potentiometers to maintain ±0.1% tolerance. This ensures consistent signal inversion 3.
- Spare Module: Keep a refurbished GE IC3600LIVD1A in anti-static storage for hot-swapping during outages, minimizing downtime to <30 minutes 9.
- System Audits: Consult GE-certified technicians for periodic compatibility audits, especially when integrating with modern control systems 6.
