Description
GE IC3600SIXKIC1C: Digital Input/Output Interface Module for Mark I/II Turbine Control Systems
Product Overview
The GE IC3600SIXKIC1C is a digital input/output (DIO) interface module designed for GE’s Mark I and Mark II Speedtronic turbine control systems. As part of the legacy IC3600 series, this module serves as a critical bridge between the control system’s central processor and field devices, enabling the transmission of discrete signals (e.g., on/off commands, sensor statuses) for turbine operation and safety interlocks. While specific datasheets for IC3600SIXKIC1C are limited, its design aligns with GE’s standards for industrial durability and modular integration, supporting applications that require high-reliability signal processing in harsh environments .
The module features a metal-enclosed PCB assembly with EMI/RFI shielding, ensuring immunity to electrical noise in industrial settings. Its front panel includes LED indicators for power (green), channel status (yellow), and fault detection (red), while the rear connectors (e.g., JC, JD) interface with field wiring or other IC3600-series boards. The IC3600SIXKIC1C is optimized for retrofitting into existing Mark I/II systems, providing a cost-effective solution for maintaining legacy infrastructure without full-system upgrades .

Key Features and Advantages
Dual-Function I/O Expansion:
The IC3600SIXKIC1C supports 16 digital inputs (e.g., proximity switches, limit sensors) and 16 digital outputs (e.g., relay coils, solenoid valves), enabling comprehensive interface with field devices. Its configurable sink/source output mode adapts to diverse wiring schemes, while optical isolation prevents ground loops and voltage spikes from compromising system stability. For example, it can monitor turbine shaft position sensors (inputs) and activate emergency shutdown relays (outputs) in case of overspeed .

Diagnostic and Fault Management:
Built-in self-test (BIST) circuitry continuously monitors channel health, with LED indicators and fault flags (sent to the control system) for rapid troubleshooting. The module’s non-volatile memory retains configuration settings during power outages, reducing restart delays. Its fail-safe design ensures outputs default to a safe state (e.g., de-energized) during faults, aligning with industrial safety standards (e.g., IEC 61508) .

Legacy System Compatibility:
As a discontinued but widely supported component, the IC3600SIXKIC1C integrates seamlessly with Mark I/II system backplanes, allowing facilities to extend the lifespan of legacy turbines. Refurbished units undergo rigorous testing (thermal cycling, signal integrity checks) to meet OEM specifications, eliminating the need for costly system overhauls. This compatibility is critical in industries like power generation, where downtime for upgrades is prohibitively expensive .

Application Areas
The IC3600SIXKIC1C is essential in industries using GE’s Mark I/II control systems:
- Power Generation: Monitors steam turbine governor valve positions (inputs) and controls lube oil pump relays (outputs) during startup. Its fail-safe outputs prevent uncontrolled turbine acceleration during voltage fluctuations.
- Oil & Gas: Deploys in pipeline compressor stations to interface with pressure transmitters (inputs) and control anti-surge valve actuators (outputs). The module’s high-temperature tolerance makes it suitable for offshore platforms.
- Industrial Turbines: Manages discrete signals for combustion turbines in cement plants, triggering fuel cutoff relays (outputs) when flame detectors (inputs) sense instability.
- Marine Propulsion: Integrates with shipboard gas turbines, processing shaft vibration sensor data (inputs) and activating cooling water valve solenoids (outputs) to maintain safe operating temperatures.

Installation and Maintenance
Installation Steps:
- Power down the control system and ground the cabinet to prevent ESD damage.
- Mount the IC3600SIXKIC1C on a 35 mm DIN rail, leaving 25 mm clearance on each side for ventilation.
- Connect shielded cables to rear connectors (JC for inputs, JD for outputs), following GE’s wiring diagram to ensure polarity and isolation.
- Verify 24V DC power supply and configure I/O channels via jumpers (e.g., input voltage range, output mode) before power-up.
Maintenance Best Practices:
- Quarterly: Inspect for corroded terminals or bulging capacitors. Use a multimeter to test channel continuity and isolation resistance (should be >100 MΩ).
- Annual: Perform a functional test using a signal generator to simulate inputs and verify output responses. Replace worn-out optocouplers if LED indicators show inconsistent behavior.
- Spare Management: Store a refurbished IC3600SIXKIC1C in an anti-static bag for hot-swapping. Ensure spare units are tested for compatibility with the existing system firmware.
Product Availability and Warranty
Refurbished IC3600SIXKIC1C 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.
