Functional Description

IS200SPROH1ABC is an Emergency Protection Terminal Board developed by GE. It is part of Mark VIe control system. The Emergency Protection (SPRO) terminal board is designed to interface with either a PPRO (Primary Protection) or YPRO (Backup Protection) I/O pack. The SPRO terminal board conditions the incoming speed signal inputs for these I/O packs, ensuring that the control system can accurately monitor the turbine's speed.

Features

• The SPRO terminal board also contains a pair of potential transformers (PTs). These transformers are responsible for providing voltage inputs from the bus and the generator, which are essential for monitoring the electrical system's operational parameters and ensuring proper synchronization and protection of the turbine generator set.
• To facilitate communication with the backup trip protection system, the SPRO terminal board includes a DC-37 pin connector. This connector is located next to the PPRO or YPRO I/O pack connector and is used to connect a cable leading to a backup trip relay terminal board. This configuration allows for an additional layer of protection, ensuring that if the primary system fails, the backup system can still initiate a trip to protect the turbine.
• In terms of primary protection, the system is equipped with components such as the PTUR, YTUR, TTUR, and a primary trip relay terminal board. These components form the primary protection system, which works alongside the backup system to safeguard the turbine from potential faults or operational issues. The combination of primary and backup protection ensures comprehensive coverage, enhancing the reliability and safety of the turbine control system.

Installation

• The terminal board and its accompanying plastic insulator are mounted on a sheet metal carrier, which is then attached to a DIN-rail. This mounting method is widely used in industrial environments for its ease of installation and modularity. The DIN-rail allows for quick installation and removal, making maintenance and replacement simple.
• As an alternative to the DIN-rail setup, the SPRO and its plastic insulator can also be mounted on a sheet metal assembly. This assembly is designed to be bolted directly into a control panel, providing a more fixed and permanent installation option. This method is suitable for environments where stability and security are prioritized over flexibility.
• For wiring connections, speed signal inputs and potential transformer (PT) inputs are wired directly to the terminal block on the board. Typically, 18 AWG wires are used for these connections, which is a standard gauge for signal and control wiring. This ensures a reliable and consistent connection for the signal inputs that the SPRO board needs to process.
• The I/O pack that interfaces with the terminal board mounts directly on the JA1 connector of the SPRO. This connection forms a direct link between the SPRO and the I/O pack, allowing the system to process inputs and outputs efficiently.

Frequently Asked Questions

What is IS200SPROH1ABC?
It is an Emergency Protection Terminal Board developed by GE under the Mark VIe series.

Why does the system need these electronic IDs?
The system uses the electronic IDs to confirm that the hardware setup is valid before starting normal operation, ensuring safety and compatibility.

When are electronic IDs checked?
The electronic IDs are checked during power initialization to confirm the correct arrangement of hardware components.

What happens if there’s a hardware mismatch?
If a mismatch is detected, the system will stop the startup sequence to prevent improper operation and potential damage.

Can I replace boards without issues?
Yes, but the replacement boards must have the correct electronic ID parts for the system to validate the hardware during initialization.
