GE IS220PTURH1B | Mark VIe Primary I/O Trip Pack Module

GE IS220PTURH1B / IS230TNTRH1C Primary I/O Trip Pack Module

Product Overview

The GE IS220PTURH1B (also referenced as IS230TNTRH1C) is a dedicated Primary I/O Trip Pack Module designed for Mark VI and Mark VIe Speedtronic turbine control systems. It performs turbine protection, trip signal processing, and breaker coil control, ensuring safe and stable operation in critical environments.

This module directly connects to the IS200TRPAS1A terminal board, which provides the physical interface to field devices. By processing discrete input and output signals, the IS220PTURH1B ensures that protective actions, including turbine trips and breaker operations, are executed promptly and accurately.

Functional Role

The IS220PTURH1B supports both simplex and Triple Modular Redundant (TMR) configurations, providing flexibility for different system architectures. It uses IONet communication for high-speed data exchange, ensuring synchronized protective actions across multiple controllers.

In addition, this module includes field-upgradable firmware, built-in self-test functions, and fault diagnostics, offering long-term maintainability and reliability in industrial applications.

Key Features

1. Handles turbine trip logic and breaker coil control for critical protection.

2. Interfaces with IS200TRPAS1A for field signal connections.

3. Supports simplex and TMR architectures for redundancy.

4. Designed for harsh environments with high heat and vibration.

5. Offers firmware upgrades and continuous diagnostic reporting.
