Product Description

GE IS200SPROS1A | Mark VIeS Emergency Protection Terminal Board (SPRO - SIL)

SIL - Compliant Terminal Board for YPRO I/O Pack, Enabling Emergency Shutdown in Turbine Control Systems

1. Product Overview

The GE IS200SPROS1A is a critical emergency protection terminal board belonging to the Mark VIeS Speedtronic turbine control system, designed to interface with the YPRO I/O pack for high - reliability safety - related functions in gas and steam turbine applications. As a SIL - compliant (Safety Integrity Level) terminal board, it features a rugged surface - mount design (15.9cm × 17.8cm) that provides dedicated terminal connections for magnetic speed pickup pulses, generator voltage inputs, and emergency trip signals. It integrates passive signal conditioning circuits to ensure accurate signal transmission to the YPRO I/O pack, which then communicates with the main controller to trigger protective shutdown actions when abnormal operating conditions are detected, such as overspeed, overvoltage, or loss of synchronization. Equipped with 24 barrier - type terminal blocks, a DC - 37 pin connector for trip relay interface, and dedicated channels for speed, voltage, and current monitoring, the board operates on 24V DC system power and supports 125V DC trip solenoid actuation. Fully compliant with GE Mark VIeS system specifications and SIL safety standards, it serves as a key component in power generation facilities that demand the highest level of operational safety and reliability, making it ideal for utility - scale power plants, industrial cogeneration systems, and critical turbine installations.

3. Typical Applications

• Gas Turbine Power Plants: Emergency overspeed protection, generator voltage monitoring, and trip signal interface in combined - cycle power plants.

• Steam Turbine Facilities: Synchronization loss protection, bearing vibration monitoring, and emergency shutdown control in thermal power stations.

• Cogeneration (CHP) Systems: Safety interlock for turbine - generator sets in industrial facilities requiring combined heat and power production.

• Critical Industrial Turbines: Emergency protection for turbines used in refineries, chemical plants, and LNG facilities.

• Turbine Retrofit Projects: Replacement of legacy terminal boards in Mark VIeS system upgrades to enhance safety and compliance.

4. Installation & Maintenance

Installation: Mount the board on a flat surface (compatible with DIN - rail or panel - mount brackets). Connect speed pickup sensors, PT voltage inputs, and current transformers to the barrier terminals. Interface the DC - 37 connector with trip relay terminals and the YPRO I/O pack connector to the Mark VIeS backplane. Apply 24V DC power and configure safety thresholds via the Mark VIeS control software; perform a system - level test to verify trip signal actuation.

Maintenance: Regularly inspect terminal block connections for corrosion or loose wiring; check signal integrity using test points. Verify 24V DC power stability and trip relay functionality quarterly. Clean the board surface to prevent dust accumulation and ensure proper heat dissipation. Replace terminal blocks or connectors if damaged to maintain safety compliance.

Fault Diagnosis: Use Mark VIeS diagnostic tools to check for signal errors; test trip relay actuation with simulated fault conditions. Verify speed pickup pulses and voltage signals with a multimeter to isolate signal conditioning or connection issues. Inspect the PCB for physical damage or component failure affecting safety functions.
