Product Overview

IS220PTURH1B is a multi‑function turbine‑specific I/O pack for GE Mark VIe speedtronic control platform. It handles turbine rotational‑speed pulse signals from magnetic‑pickup sensors, process‑analog‑loop acquisition and discrete‑contact‑status feedback for gas‑turbine and steam‑turbine prime‑mover control. Dual‑port redundant IONet Ethernet links guarantee high‑availability communication to Mark VIe controller. It is widely used for turbine speed‑measurement, auxiliary‑system‑status monitoring and combustion‑process‑variable acquisition. Obsolete turbine‑control spare hardware available as refurbished and surplus tested units for legacy power‑plant‑control‑rack repair‑projects.

Application Notes

‑ Mount onto matching PTUR‑series terminal‑base assembly; observe strict ESD handling rules. ‑ Route magnetic‑pickup shielded cables separately from high‑voltage power‑cables to reduce EMI interference. ‑ Configure channel‑parameters within ToolboxST software. ‑ Typical deployment: power‑plant Mark VIe turbine‑I/O‑pack spare‑part stocking.
