Product Introduction
The IS220YTURS1A is a Turbine Input/Output Pack module designed for the Mark VI / Mark VIe turbine control system architecture. It serves as a modular I/O pack that interfaces turbine signals (such as speed pickups, flame detectors, trip relay outputs, emergency stop circuits) with the central control network.
This module enables integration of multiple discrete and analog inputs/outputs associated with turbine and generation equipment into the broader control system I/O rack. It supports modular replacement, plug-in installation in the I/O rack, and works with terminal boards designated for turbine systems.
Because of its purpose-built nature, the IS220YTURS1A is used in applications where turbine control, monitoring, protection and feedback are essential. It supports high-reliability installation, good diagnostics, and is part of the broader IS220 family of I/O packs used in turbine and process control environments.

Applications
The IS220YTURS1A module is used in numerous industrial and power-generation scenarios including:
-
Gas turbines: capturing speed pickup signals, flame detector inputs and interfacing trip logic for turbine control.
-
Steam turbines: providing turbine shaft speed feedback, emergency stop logic, and interfacing with turbine terminal boards.
-
Generator control systems: linking turbine I/O signals into generation control and protection systems.
-
Offshore or marine turbo-generator platforms: rugged I/O pack module for turbine accessory signals.
-
Retrofit or upgrade of existing turbine control racks: replacing older modules while retaining Mark VI/Mark VIe infrastructure.
Advantages
Choosing the IS220YTURS1A offers several key benefits:
-
Purpose-built for turbine signals: Tailored for turbine speed, flame, trip, E-stop and other turbine-specific I/O rather than generic pack.
-
Compact and modular: At approximately 165 × 100× 35 mm and ~1.26 kg, it fits into dense I/O racks without excessive space or weight penalty.
-
Reliable under industrial conditions: Supports wide temperature range (–30 °C to +65 °C) and protection for demanding field installations.
-
Redundant network ready: Dual Ethernet ports enable I/O network redundancy and improved system availability.
-
Field-serviceable: Plug-in design allows fast replacement and integration in modular racks, decreasing downtime.
-
Ecosystem compatibility: As part of the IS220 family and turbine control terminal board interface sets, it integrates with existing Mark VI/Mark VIe I/O architecture.
