Product Introduction
The IS220PPROS1B is a dedicated Emergency Turbine Protection I/O Pack module designed for high‑availability control systems in turbine and power‑generation applications. It is part of the IS220 family of modular I/O packs used in the Mark VI/Mark VIe system architecture.
It functions as a backup trip logic interface, interfacing into turbine emergency trip boards (e.g., TREG, TREL, TRES, TREA) and providing redundant monitoring of overspeed, deceleration fault, generator synchronisation and other critical protection signals. In a typical triple‑modular redundant (TMR) protection configuration, three IS220PPROS1B modules form a robust backup path independent of the main control module.
The design emphasises fast response, high reliability, redundant communications, rugged industrial operation, and seamless integration into existing I/O racks—making it suitable for mission‑critical turbine installations.

Applications
The IS220PPROS1B module is used extensively in the following environments:
-
Gas & Steam Turbine Systems: Employed as the backup trip I/O pack interfacing to emergency trip boards, monitoring overspeed sensors, deceleration faults and generating trip signals independent of the main controller.
-
Power Generation Plants: Integrated into turbine‑control cabinets where reliability and redundancy are paramount, managing critical protection logic that must operate even when the main control system fails.
-
Oil & Gas Platforms and Offshore Installations: Placed in harsh, demanding environments where stand‑alone protection logic is required for continuous operation, often in explosion‑risk zones.
-
Industrial Process Plants: In systems requiring fail‑safe, redundant I/O packs for safety or protection roles (e.g., large compressors, generators, spinning masses) where the module acts as a safety interface.
-
Retrofit / Upgrade Projects: Where legacy turbine protection modules are replaced by modern packs compatible with Mark VI/Mark VIe rack architecture, enabling improved diagnostics and maintainability without full system redesign.
Advantages
When selecting the IS220PPROS1B module, the benefits include:
-
Dedicated protection‑grade interface: Designed specifically for turbine emergency trip logic rather than generic I/O, ensuring optimized response and reliability.
-
High redundancy architecture support: Compatible with TMR configurations so the system remains operational even if one or two modules fail.
-
Dual‑Ethernet communication paths: Network fault tolerance with automatic fallback ensures trip logic continues uninterrupted.
-
Compact, serviceable design: With modest weight (~0.45 kg to ~1.1 kg) and plug‑in form factor, the module is easy to install or replace in dense control cabinets.
-
Wide industrial environmental tolerance: Designed to operate in ambient conditions from –30 °C (or –20 °C) up to +65 °C (or +70 °C) with storage up to +85 °C.
-
System ecosystem integration: Fully compatible with IS220 family racks and turbine control boards, enabling seamless upgrades and reducing risk.
-
Improved diagnostics and maintainability: Enhanced self‑test, LED indicators, and standardized installation reduce troubleshooting time and maintenance cost.
