Functional Description

IS230TSPRH2C is an Emergency Protection Module developed by GE. It is a part of Mark VIe control system. Speed control and overspeed protection are implemented using six passive, magnetic speed pickups. These components are essential for ensuring safe and reliable operation by monitoring and regulating the speed of the machinery. The system is designed with redundancy and precision to protect against overspeed conditions, which can lead to equipment damage or failure.

Features

• Speed Control: The first three magnetic speed pickups are monitored by the controller. The controller uses the median signal from these pickups for precise speed control and primary overspeed protection. This approach ensures accurate speed measurement and enhances the reliability of speed control by mitigating the impact of any single faulty pickup.
• Overspeed Protection: Overspeed protection is a critical safety feature that prevents machinery from exceeding safe operational speeds. The second set of three magnetic speed pickups is separately connected to the three Relays in the protection module. This independent connection ensures that overspeed protection remains functional even if the primary speed control system encounters issues Redundancy and Reliability: The implementation of speed control and overspeed protection with multiple pickups and separate monitoring pathways enhances the system's redundancy and reliability. By using three pickups for speed control and another three for overspeed protection, the system ensures that both functions can operate independently, reducing the risk of a single point of failure.
• Active Pulse Rate Transducers (TTL Type): In addition to passive magnetic speed pickups, the board can also support active pulse rate transducers (TTL type). These transducers convert speed signals into a format that the VPROs can monitor and process, providing flexibility in the types of speed-sensing equipment that can be used with the system.

FREQUENTLY ASKED QUESTIONS

What is IS230TSPRH2C?
It is an Emergency Protection Module developed by GE

What are active pulse rate transducers (TTL type)?
Active pulse rate transducers (TTL type) are sensors that convert speed signals into a format that can be monitored. They provide an alternative to passive magnetic speed pickups and can be used for precise speed measurement and protection.

Why is redundancy important in speed control and overspeed protection?
Redundancy ensures that both speed control and overspeed protection functions can operate independently, reducing the risk of a single point of failure and enhancing the overall reliability of the system.

How does the system handle potential single-point failures?
The system is designed with separate pathways for speed control and overspeed protection, using different sets of speed pickups. This separation minimizes the impact of any single-point failure and ensures continuous protection and control.
