GE IS200ADIIH1A
- Product Name: Mark VI Auxiliary Drive to ISBus Interface Board
- Product Introduction: A printed circuit board manufactured by GE for the Mark VI Speedtronic turbine control system. It provides the interface between AC/DC2000 drives and the ISBus LAN network, enabling deterministic communication between the drive and the main controller.
Detailed content
- Technical Specifications:
- Manufacturer: GE Industrial Systems
- Series: Mark VI
- Part Number: IS200ADIIH1A
- Form Factor: 263 × 138 × 88 mm
- Weight: 2.35 kg
- Instruction Manual: GEI-100305
- Compatible Drives: AC/DC2000 (requires LDCC board)
- Programmable Frame Rates: 1 ms, 2 ms, 4 ms, 8 ms
- Connectors: 4 RJ-45, 2 plug connectors
- Fuses: None
- Jumpers: None
- Diagnostic Features: Status LEDs and testpoints
- Bypass Relay: Present to maintain network connectivity regardless of drive power state
- Functional Features: Single ISBus controller (drop 0) supporting up to 31 nodes; daisy-chain byte-stream communication where each node substitutes its feedback data in place of its reference; built-in bypass relay maintains full network connection irrespective of drive power condition.
- Application Scenarios: Critical interface board in AC/DC2000 Innovation drive systems for GE gas and steam turbine control.
- Working Principle: The board connects to the DS200LDCC Drive Control/LAN Communications Board via LNPL ribbon cable and COM1 wire. It introduces a 200 μs time delay to allow the LAN Control Processor to write drive feedbacks into the ISBus controller before the next frame starts.
- Installation Requirements: Mounts to the rear of the first AC/DC2000 board carrier. The LDCC board must be present—the IS200ADIIH1A cannot be used alone or with previous LAN communication boards. Configuration is performed via the keypad on the LDCC board or the GE Control System Toolbox.
- Usage Notes: No hardware jumpers or fuses are present; rely on software configuration. Use the seven TP test points for diagnostics. Refer to GEI-100305 for full functional description, application data, and renewal procedures.
