Product Introduction
The IS220PPROH1A is a Backup Protection / Turbine Emergency Trip I/O Pack module belonging to the Mark VIe distributed control system family.
It is designed to act as a high-reliability protection interface for turbine systems, particularly aeroderivative gas turbines or steam turbines, providing backup trip logic, overspeed protection, generator synchronization monitoring, and redundant communication paths.
The module allows direct interface to specific turbine field devices (e.g., trip boards such as TREG, TREL, TRES, TREA) and can be configured for triple-modular redundancy (TMR) in protection architectures.
Its compact size, robust design and dedicated purpose make it suitable for emergency protection loops where fault tolerance and rapid response are critical.

Applications
The IS220PPROH1A is employed in high-demand industrial environments including:
-
Gas turbine emergency shutdown systems: providing independent protection logic separate from the main control system, implementing overspeed, deceleration fault, loss of flame, etc.
-
Steam turbine protection: handling trip logic, synchronous generator protection, and interfacing to dedicated trip boards.
-
Power generation plants: acting as backup protection layer in turbine control systems, improving safety and system uptime.
-
Oil & gas platforms: where turbines and generators must be protected with fault-tolerant hardware in offshore or harsh conditions.
-
Retrofit or modernization projects: replacing older protection modules with a dedicated I/O pack that fits into the Mark VIe rack and offers high reliability.
Advantages
-
High fault-tolerance: Designed for use in TMR architectures, ensuring backup protection even if main controller fails.
-
Dedicated protection functionality: Built specifically for turbine trip and protection systems rather than generic I/O, hence optimized for speed and reliability.
-
Compact size and significant weight margin: Dimensions 222 × 144 × 88 mm, weight 2.5 kg—easy to integrate into existing racks.
-
Wide temperature range: Operates from –40 °C up to +85 °C, enabling use in harsh environments.
-
Dual ethernet ports: Provides redundancy in communication links, improving system availability.
-
Direct interface to turbine trip boards: Reduces need for additional instrumentation, simplifies wiring and reduces maintenance.
-
Industry-specific heritage: Part of the Mark VIe I/O Pack family, widely used and trusted in turbine applications.
