Core Function 

PRTD temperature measurement I/O pack for Mark VIe turbine control system. It collects temperature signals from field PT100 RTD sensors of turbine bearing, stator and cooling system. Converts resistance variation into digital temperature value, transmits data to main controller through dual‑port IONet redundant Ethernet. Supports simplex, dual and TMR triple‑modular redundant architecture, completes equipment temperature monitoring, over‑temperature alarm and interlock protection logic for turbo‑generator units.

Product Details 

The IS220PRTDH1B (336A5026ADP13) is PRTD series RTD temperature measuring I/O pack for GE Speedtronic Mark VIe distributed turbine control system.

This hot‑swappable compact I/O pack is installed in Mark VIe standard rack and works with matched RTD terminal board for field sensor wiring. It supports 2‑wire and 3‑wire PT100 thermal resistance sensors, adopts stable resistance sampling circuit to reduce measurement error caused by cable resistance. Built‑in hardware filter can effectively filter site high‑frequency interference and improve temperature acquisition accuracy. Dual‑port IONet redundant Ethernet guarantees reliable data interaction with main controller. IR infrared diagnostic port supports on‑site parameter checking and fault diagnosis without upper computer. Front‑panel LED indicators help technicians observe running status and locate channel failures rapidly.

Conformal coated circuit board improves anti‑vibration, moisture‑proof and anti‑electromagnetic‑interference performance, adapts to harsh working environment of power‑plant turbine hall. Module supports automatic configuration after replacement and shortens equipment maintenance downtime.

It belongs to key temperature signal processing spare‑part for Mark VIe turbine control system, widely used in overhaul and renovation projects of gas‑steam turbo‑generator units.

It is important spare hardware for turbine temperature loop debugging and defective IS220PRTDH1B pack replacement.
