Présentation du produit
The GE IS200PDIOH1A is a Digital/Discrete I/O Protection Board designed for integration within the GE Speedtronic Mark VI / Mark VIe turbine control systems. It serves as a critical interface that processes discrete digital I/O signals (e.g. trip contacts, interlocks) related to turbine protection logic.
This board connects to terminal blocks and communicates via the IONet backplane (through the VCMI module), enabling fast, deterministic exchange sur status and control signals. It is typically used in redundancy-critical protection systems—such as emergency trip logic—where accurate digital signal handling and high reliability are essential for safe turbine operation.

Questions fréquentes (FAQ)
-
What discrete signal types are supported by IS200PDIOH1A?
Inputs accept contact closures, high/low logic; outputs drive discrete alarms or enable signals. -
Does the board provide channel isolation?
Yes, channel-to-ground isolation is provided; channel-to-channel isolation depends on the chassis layout. -
Can this board operate in a redundant safety configuration?
Yes, it supports redundant trip logic and dual-path discrete signal processing. -
How are faults or logic errors reported?
Built-in diagnostics flag faults via VCMI communication to the controller and can drive LED indicators on terminal boards. -
Is this board hot-swappable?
N° It requires system shutdown for installation or removal. -
Which communication protocol is used?
Discrete I/O and diagnostics are sent over IONet via the VCMI card in the controller rack. -
Does it support both input and output channels?
Yes – it handles discrete inputs (e.g., contact closures) and outputs (e.g., alarm/enabling signals). -
What terminal boards are typically used with IS200PDIOH1A?
Compatible terminal boards include discrete input and relay output terminal boards (e.g., IS200STCIH series). -
Is wiring-to-terminal board mapping verified?
Yes—diagnostic checks verify terminal board IDs, wiring integrity, and logic consistency. -
Can it be used in non-turbine industrial systems?
While optimized for GE Mark VI/VIe, it may be adapted to other discrete safety logic environments with custom integration.
