Description
GE IC3600SIXJ1A1A: Power Supply Selector Control Card for Mark I/II Turbine Control Systems
Product Overview
The GE IC3600SIXJ1A1A is a power supply selector control card designed for integration with GE’s Mark I and Mark II Speedtronic turbine control systems. As part of the IC3600 series, this module manages power distribution and fault detection within the control system, ensuring stable operation of critical components like relays, solenoid valves, and field devices. While specific datasheets for IC3600SIXJ1A1A are limited, its functionality aligns with GE’s legacy system architecture for power monitoring and redundancy management .
Engineered for industrial durability, the IC3600SIXJ1A1A features a metal-enclosed PCB assembly with EMI shielding, ensuring reliable performance in high-vibration environments (up to 5G) and wide temperature ranges (-20°C to +70°C). Its design includes multiple connector ports (e.g., JC, JD, JE) for interfacing with power distribution modules (PDMs) and control boards, while LED indicators—green (power), yellow (warning), red (fault)—provide real-time status feedback for troubleshooting .

Key Features and Advantages
Dual Power Supply Redundancy:
The IC3600SIXJ1A1A supports redundant 125V DC power inputs, automatically switching to a backup supply in case of primary failure. This ensures continuous operation of critical systems (e.g., turbine governor controls) during power fluctuations. Its voltage divider circuit reduces the input signal to 5.09V DC for transmission to the control system’s analog-to-digital converter (e.g., GE IC3600HAIC1B), enabling precise monitoring of power bus health .

Ground Fault Detection:
The module continuously monitors ±62.5V DC segments of the power bus for ground faults, triggering alarms and isolating faulty sections to prevent cascading failures. Its latching alarm logic ensures no missed events until manually reset, while fail-safe outputs default to a de-energized state during faults, aligning with industrial safety standards (e.g., IEC 61508) .

Rugged Industrial Design:
Housed in a metal enclosure with screw-terminal connections, the IC3600SIXJ1A1A withstands extreme industrial conditions. Its modular PCB layout facilitates component-level repairs, while strain-relieved wiring prevents loose contacts in high-vibration settings. The card’s LED indicators reduce troubleshooting time by up to 40% compared to non-indicated modules .

Legacy System Compatibility:
As a discontinued yet widely supported component, the IC3600SIXJ1A1A offers a cost-effective solution for maintaining Mark I/II systems. Refurbished units undergo rigorous testing (thermal cycling, signal accuracy checks) to meet OEM standards, eliminating the need for full-system upgrades. This compatibility extends operational lifespans by up to a decade, making it ideal for facilities prioritizing reliability on legacy infrastructure .

Installation and Maintenance
Installation Preparation:
- Power down the control system and ground the cabinet to prevent ESD damage. Mount the IC3600SIXJ1A1A on a 35 mm DIN rail, ensuring 50 mm clearance for heat dissipation.
- Connect shielded cables to rear connectors (JC for power input, JD for signal output), following GE’s wiring diagram to avoid cross-circuiting. Verify input voltage (125V DC) and signal compatibility before power-up .
Maintenance Recommendations:
- Quarterly Inspections: Check for swollen capacitors, corroded terminals, or discolored resistors. Replace faulty components immediately to maintain signal integrity.
- Annual Calibration: Use a precision multimeter to validate voltage scaling accuracy, adjusting potentiometers to ensure readings align within ±0.1% tolerance.
- Spare Module: Keep a refurbished IC3600SIXJ1A1A in anti-static storage for hot-swapping during outages, reducing downtime to <30 minutes.
Product Availability and Warranty
Refurbished IC3600SIXJ1A1A modules are typically available from industrial automation suppliers (e.g., AxControl, World of Controls) with a 1-year warranty covering component defects. Suppliers provide detailed test reports (e.g., voltage tolerance, isolation breakdown voltage) and 24/7 technical support for configuration issues. Delivery times range from 1–5 business days, with expedited shipping options for critical applications .
Note: Due to the legacy nature of Mark I/II systems, ensure compatibility with existing backplane versions (e.g., Mark I Type 3 or Mark II Type 4) before purchasing. Contact GE-certified service centers for system compatibility audits.
