Product detail description: VPROH2B IS215VPROH2BC GE turbine protection plate
Emergency overspeed protection: The core function of the VPROH2B protection board is to provide emergency overspeed (EOS) protection for the turbine. It monitors the speed of the turbine and triggers an emergency stop when exceeding preset safety limits to prevent equipment damage or safety accidents.
Redundant design: IS215VPROH2BC consists of three redundant VPRO boards, which ensures that even if one board fails, the other boards can continue to provide protection, thereby improving the reliability and safety of the system.
Speed control and monitoring: The protection board uses six passive magnetic speed sensors to monitor the speed of the turbine, and achieves precise speed control and overspeed protection through control logic and algorithms. It also has thermocouples and analog inputs for monitoring key parameters such as gas turbine exhaust temperature.
Trip function: The VPROH2B protection board works in conjunction with the TREG and TRPG terminal boards to manage up to 12 relays and operate three trip solenoid valves through voting inputs. These relays and solenoid valves work together to achieve emergency tripping of the turbine.
Communication capability: The protection board has Ethernet connection and supports communication between IONet and control modules. This enables the protection board to transmit data and receive instructions with other system components, enhancing the integration and coordination of the entire control system.
The GE VPROH2B IS215VPROH2BC turbine protection board is a high-performance and highly reliable protection component provided by GE for its gas and steam turbine control systems. It provides comprehensive emergency overspeed protection and emergency shutdown functions for the turbine through redundant design, precise speed control and monitoring, and powerful communication capabilities.
Product details and parameters: VPROH2B IS215VPROH2BC GE turbine protection board
Power supply: The VPROH2B protection board uses 125V DC voltage from the cabinet PDM and internally converts it into 5V and 28V DC voltage to power various components.
Indicator light: There are LED indicator lights on the front panel to display the status of the protection board (such as RUN, FAIL, and diagnostic alarms).
Interface: including power plug, Ethernet ID connector, IONet port (Ethernet), and parallel port, used to connect external devices and systems.
VPROH2B IS215VPROH2BC application areas:
The GE VPROH2B IS215VPROH2BC turbine protection plate is widely used in various gas and steam turbine control systems, especially in industries such as electricity, oil, and natural gas that require high reliability and safety assurance.
