The GE IS200DTAIH1ABB is a key module of GE's Mark VIe Turbine Control System, belonging to the Digital Input/Output (DI/O Module) category. This series is primarily used for the control and protection of industrial steam turbines and gas turbines, commonly applied in large-scale industrial scenarios such as power generation, petrochemicals, and metallurgy.
Core Functions
Processes Digital Input (DI) and Digital Output (DO) signals to achieve logical control, status monitoring, and protection for turbine systems.
Connects with turbine sensors (e.g., speed probes, limit switches) and actuators (e.g., solenoid valves, relays) to transmit switching signals (e.g., "start/stop" commands, valve status feedback).
Technical Features
Channel Quantity: Typically includes multiple independent digital channels (specific quantity refer to the manual, typically 16 DI/16 DO).
Signal Types:
Input: Supports DC or AC signals (e.g., 24 V DC, 120 V AC) with optoelectronic isolation for anti-interference.
Output: Relay or Solid State Relay (SSR) output, with a driving capacity of up to 2 A per channel (for controlling solenoid valves, indicator lights, etc.).
Communication Interface: Connects with the main control module (e.g., IS200TBCVH1) via the Mark VIe system backplane bus for high-speed and real-time data transmission.
Redundancy Design: Supports hot redundancy configuration (requires a redundancy kit) to enhance system reliability and avoid single-point failures.
Diagnostic Functions: Built-in self-diagnosis mechanisms detect channel faults, power anomalies, etc., with alarms indicated via LED lights or system software.
- Power Industry: Start/stop control, speed regulation, and emergency shutdown (ESD) protection for steam turbines in coal/gas-fired power plants.
- Petrochemical Industry: Control of steam turbines driving compressors, pumps, and other rotating machinery to ensure stable process operations.
- Metallurgy and Manufacturing: Condition monitoring of large industrial steam turbines, such as load distribution and safety interlocking for steam turbines in steel plants.
- Dimensions: Standard rack-mounted module compatible with GE Mark VIe control cabinets (approximately 4.5 inches wide, 17 inches tall, 12 inches deep).
- Power Supply: Powered by DC from the control cabinet backplane (typically 24 V DC), with low power consumption (typical <10 W).
- Installation Method: Inserted into the designated slot of the Mark VIe system rack, fixed via rails and latches, supporting hot-swapping (if allowed by the system configuration).

Technical Documentation Keywords
Look for sections such as Mark VIe Turbine Control System or Digital I/O Module Specifications in the manual to obtain channel definitions, wiring diagrams, and fault code explanations.
Precautions
This module is a specialized industrial control component and must be used with the Mark VIe main control system, not as a general-purpose PLC module.
Follow GE safety guidelines during replacement or debugging to avoid equipment downtime or safety incidents due to misoperation.
- Sister Modules: GE IS200DTAIH2ABB (possibly an upgraded version supporting more channels or higher voltages).
- Replacement Suggestions: If the module is discontinued, GE may offer compatible Mark VIe series upgraded modules (e.g., new DI/O modules with Ethernet communication). Contact the technical team to assess compatibility.
