The GE IS230TDBTH2A (ordering reference: IS200TDBTH2ACD) is a PDIO (Power Distributed Input/Output) Terminal Board used in GE Mark VIe / Mark VIeS turbine control systems. It is designed to interface directly with discrete I/O packs, providing structured termination for field contact signals and ensuring safe, stable communication between field devices and the control system.
This module is engineered for high-integrity industrial signal handling, supporting redundant architectures and hazardous-location applications where reliability and fault tolerance are critical.
