GE IS200ADIIH1AAA Auxiliary Drive Interface Boards

The GE IS200ADIIH1AAA, also cataloged as the IS200ADIIH1AAA Auxiliary Drive to ISBus Interface Board, operates as a dedicated hardware component for LAN communication and drive-to-network integration within Mark VI turbine control and AC/DC2000 drive architectures. Configured for high-speed data exchange, the GE IS200ADIIH1AAA (IS200ADIIH1AAA Auxiliary Interface Board) provides direct electrical execution of ISBus local area network (LAN) interfacing and drive-centric control sequencing.

Hardware Specifications

Industrial Control and Protection Metrics

• Backplane Bus Communication Velocity: The board interfaces with the LDCC (LAN Control Processor) board to facilitate high-speed data transfer between the ISBus and the drive control processor. The architecture supports configurable frame times (1, 2, 4, or 8 ms) to ensure deterministic control logic execution across the LAN.
• Profinet / EtherNet/IP Deterministic Networks: While utilizing the proprietary ISBus protocol, the board ensures deterministic timing for reference bits and feedback data. Each connected drive contributes approximately 0.20 ms to the total bus sweep rate, allowing for precise synchronization of I/O data across the turbine automation assembly.
• I/O Density Scaling: The interface supports six programmable parameters (including ADII Node Number and ADINID) stored directly within the drive's non-volatile memory. This allows for scalable configuration of interface parameters via the GE Control System Toolbox software or the local keypad of the LDCC board.
• Firmware Flash Compatibility: The module includes onboard LED indicators and seven testpoints for diagnostic verification. It is designed to function as an extension of the drive control logic, where interface parameters are updated automatically during drive reset or power-up sequences.

Frequently Asked Questions

Q: Does the IS200ADIIH1AAA support hot-swapping within the drive control rack?

A: No. The IS200ADIIH1AAA is not designed for hot-swapping. The drive power must be fully isolated before installation or removal to prevent potential damage to the high-speed communication pins or the drive backplane.

Q: What is the purpose of the onboard bypass relay?

A: The board incorporates a bypass relay to maintain ISBus electrical continuity even if the host drive is powered down. This ensures that the LAN segment remains intact, preventing communication faults from propagating to other nodes on the ISBus.

Field Installation Guidelines

• Static Sensitivity: The board is highly sensitive to electrostatic discharge (ESD). Always utilize a grounded wrist strap and anti-static mat during handling to prevent latent damage to the onboard microprocessors.
• Interface Requirements: This board is strictly limited to AC/DC2000 drives equipped with an LDCC board. It is incompatible with legacy drive control and LAN boards. Verify the presence of the LDCC board before attempting installation.
• Configuration Verification: Parameters are loaded from the drive memory during power-up. If communication is not established, verify the ADII Node Number and ADINID settings using the Control System Toolbox to ensure there are no network address conflicts on the ISBus.
