GE IS230TDBTH6A IS200TDBTH6ABC Discrete I/O Board

Product Introduction

The GE IS230TDBTH6A IS200TDBTH6ABC is a discrete I/O board developed for GE Mark VIe and Mark VIeS control systems. It is designed to manage and interface discrete field signals with the control processor, enabling reliable monitoring and control of on/off states in complex industrial environments.

This board functions as a key part of GE’s distributed I/O architecture, allowing discrete signals from switches, relays, interlocks, and auxiliary devices to be accurately transmitted and processed. Its design focuses on stability, deterministic response, and long-term operational reliability in mission-critical applications.

The IS230TDBTH6A is commonly deployed in power generation and heavy industrial automation systems, where precise discrete signal handling is essential for safe and efficient operation.
