GE IS200DTAIH1ACC Mark VI Digital Input Terminal Board
Manufacturer: GE / Baker Hughes
Model: IS200DTAIH1ACC
Series: Speedtronic Mark VI (IS200)
Type: Digital Input Terminal Board (DTAI)
Function: 24VDC digital signal acquisition, interface for switches, sensors, and contactors in turbine control systems
1. Overview
The GE IS200DTAIH1ACC is a **16-channel isolated digital input terminal board** for the Mark VI turbine control system. It serves as the critical interface between field devices (limit switches, proximity sensors, relay contacts) and the main controller, converting 24VDC on/off signals into logic-level data. Designed for simplex, dual, or TMR architectures, it provides electrical isolation, noise filtering, and channel diagnostics for turbine protection and safety interlock circuits in power generation, oil & gas, and industrial automation. It installs in standard Mark VI VME racks and supports IONet communication.
