The GE IS230PCAAH1B is a Core Analog I/O Module, a critical component of the Mark VIe Distributed Control System designed for precise analog signal processing in gas turbine operations.

• Comprehensive Analog I/O: Supports diverse signal types including thermocouples, 4-20 mA loops, LVDT inputs, seismic data, pulse rates, and servo outputs for comprehensive turbine monitoring and control.
• Redundancy Flexibility: Compatible with simplex, dual, and TMR configurations for mission-critical applications requiring maximum reliability.
• Unified Module Design: Integrates shared processor board and application I/O boards as a single replaceable unit for simplified maintenance.
• Seamless Connectivity: Connects to TCAT terminal boards via 68-pin cables with dual Ethernet ports for robust IONet communication with Mark VIe controllers.
• Precision Performance: Operates at 10 ms and 40 ms frame rates with defined accuracy standards for reliable data in all operating conditions.
• Robust Power & Grounding: Includes 28V DC input with current limiting and JGPA board integration for shield grounding to ensure signal integrity.
• Diagnostic Capabilities: Features status LEDs, internal temperature sensors, and electronic ID reading for efficient troubleshooting.

The module comprises a shared processor board, two application I/O boards, and a terminal board engineered as a unified assembly. It connects to TCAT terminal boards via 68-pin cables and draws power through a 28V DC connector, while a JGPA board provides shield ground and 24V field power.
