GE IS220PPROS1B is an emergency turbine protection I/O module from General Electric(GE).It is designed for high-reliability safety control of gas turbines and steam turbines and is a core component of the Mark VIe series control system.The following is a product introduction:
I.Core functions and application scenarios
Emergency protection and real-time monitoring
This module is used to monitor key parameters(such as speed,pressure,temperature,etc.)in turbine operation,and trigger emergency shutdown when overspeed,overpressure or abnormal operating conditions are detected to prevent equipment damage or safety accidents.Its fast response time(millisecond level)ensures timely activation of the protection mechanism.
Redundant fault-tolerant design(TMR)
Adopting triple modular redundancy(TMR)architecture,fault self-detection and fault tolerance are achieved through the majority voting mechanism of three independent modules,which meets the SIL 3 safety integrity level and is suitable for scenarios with strict reliability requirements such as nuclear power and petrochemicals.
Compatibility and scalability
Supports collaboration with the main control system(such as PTUR module),can be integrated into distributed control systems,compatible with RS-232/RS-422 and other communication protocols,suitable for power plants,industrial facilities and large turbine equipment.
2.Technical parameters and performance
Power input:24V DC to 32V DC,typical power consumption 12.5W.
Operating temperature:-40°C to 85°C,protection level IP65(some models).
Relay channel:12 discrete outputs,support hard overspeed protection logic.
Communication interface:2 Ethernet ports(IONet protocol),support redundant communication paths.
3.Design features
Modularity and easy maintenance
Adopting modular design,supporting hot plugging,the faulty module can be quickly replaced without stopping;the LED indicator shows the operating status in real time,simplifying the fault diagnosis process.
High-precision signal processing
Supports mixed input of analog and digital quantities,with signal filtering and scale conversion functions,suitable for signal acquisition in complex industrial environments.
Safety certification
Passed CE,UL and other international certifications,and complies with the safety standards of nuclear power,chemical and other industries.
