Product Overview

IS230PCAAH1B is the core‑analog processing I/O module for GE Mark VIe turbine‑control platform, designed for high‑density multi‑sensor acquisition and servo‑actuator drive for gas‑turbine and steam‑turbine prime‑mover control. It processes vibration, displacement, temperature, process‑loop and rotational‑speed signals received from IS230TCATH1A termination board, and generates servo‑coil drive outputs for turbine fuel‑valve and actuator control. Dual redundant IONet Ethernet links guarantee high‑availability communication to Mark VIe controllers. Obsolete heavy‑duty turbine‑control spare hardware available as refurbished and surplus tested units for power‑plant control‑system retrofit projects.

Application Notes

‑ Module cannot operate standalone; requires IS230TCATH1A terminal‑board assembly. ‑ Strict ESD protection required during card insertion / removal. ‑ Match firmware revision with existing Mark VIe system via ToolboxST software. ‑ Typical deployment: power‑plant Mark VIe core‑analog processor‑module spare‑part stocking.
