Description
Product Overview
The GE VPROH2B IS215VPROH2BC is a highly advanced and reliable protection module designed specifically for steam and gas turbine control systems. As an integral part of GE’s industrial automation product portfolio, it plays a crucial role in safeguarding the safe and efficient operation of turbines.
At its core, the VPROH2B protection board is engineered to offer emergency overspeed (EOS) protection. It continuously monitors the turbine’s speed with high precision. In the event that the turbine’s speed exceeds the preset safety limits, it promptly triggers an emergency stop mechanism. This rapid response is vital as it effectively prevents potential equipment damage and safety accidents that could occur due to excessive speed.
The IS215VPROH2BC is constructed with a redundant design, consisting of three redundant VPRO boards. This redundancy is a key feature that significantly enhances the system’s reliability and safety. Even if one of the boards encounters a malfunction, the other two can seamlessly continue to provide the necessary protection functions. This ensures that the turbine’s protection system remains operational at all times, minimizing the risk of system failures.

VPROH2B IS215VPROH2BC
Main Features and Advantages
Precise Emergency Overspeed Protection
The GE VPROH2B IS215VPROH2BC offers highly accurate emergency overspeed protection. By using six passive magnetic speed sensors, it can precisely monitor the turbine’s speed. Through sophisticated control logic and algorithms, it can achieve both accurate speed control and effective overspeed protection. This level of precision helps in maintaining the optimal performance of the turbine and protecting it from the harmful effects of overspeed.
Redundant Design for High Reliability
The triple – redundant design of the IS215VPROH2BC is a major advantage. In case of a failure in one of the VPRO boards, the remaining two boards can take over the protection functions without any interruption. This redundancy significantly reduces the probability of system failures and downtime, ensuring the continuous and reliable operation of the turbine protection system.
Comprehensive Parameter Monitoring
In addition to speed monitoring, the module also has thermocouples and analog inputs. These allow it to monitor key parameters such as the gas turbine exhaust temperature. By keeping track of multiple critical parameters, the VPROH2B IS215VPROH2BC can provide a more comprehensive protection solution, enabling early detection of potential issues and taking appropriate actions to prevent major problems.
Effective Trip Function
The VPROH2B protection board works in tandem with the TREG and TRPG terminal boards. It can manage up to 12 relays and operate three trip solenoid valves through voting inputs. This coordinated operation of relays and solenoid valves enables the quick and reliable emergency tripping of the turbine when required, adding an extra layer of safety to the overall system.
Good Communication Capability
Equipped with an Ethernet connection, the protection module supports communication between the IONET and control modules. This enables seamless data transmission and instruction reception between the protection board and other components of the system. As a result, it enhances the overall integration and coordination of the entire control system, allowing for more efficient operation and management.
