GE Mark VIe IS220PPROH1A Backup Turbine Protection I/O Module

GE Mark VIe IS220PPROH1A Backup Turbine Protection I/O Module

IS220PPROH1A is a backup turbo protection I/O module (PPRO) for the GE Mark VIe control system, which is an independent safety protection card used in conjunction with SPRO/TPRO terminal boards.
The core function of IS220PPROH1A is to achieve backup overspeed protection, ETS emergency tripping, generator synchronization verification for steam turbines and gas turbines independently of the main controller circuit, while providing independent watchdog monitoring for the main control circuit; Collect signals from three magnetic electric speed probes, and quickly trigger shutdown when the speed exceeds the standard to prevent damage to the unit caused by runaway. IS220PPROH1A is a critical safety component of the unit SIS safety protection circuit, supporting TMR triple redundancy configuration to enhance protection reliability.

GE Mark VIe IS220PPROH1A Backup Turbine Protection I/O Module

Product Features

1.  Independent protection architecture, isolated from the main control CPU, can still execute overspeed trip protection in case of main control failure, without relying on the main control logic.
2.  Support TMR triple redundancy configuration, two out of three voting, significantly reducing the risk of false tripping and refusal to trip, and meeting the SIS safety standards of power plants.
3.  Dual port IONet redundant communication ensures stable data exchange with the Mark VIe system and real-time upload of speed and alarm status.
4.  Extremely fast hardware trip response, hardware level circuit output, low latency, meeting the millisecond level action requirements of power unit overspeed protection.
5. Equipped with status indicator lights such as RUN, ESTP, LINK, WDOG, etc., it facilitates quick troubleshooting and judgment of circuit status on site.
6. Supports hot swapping and online rack replacement, without affecting the normal operation of other protection circuits in the same rack.
7.  Wide temperature and humidity design, suitable for industrial environments with large temperature differences and high dust levels such as power plant control rooms and gas turbine auxiliary rooms.
8.  Integrated wire breakage detection function, which can monitor the wire breakage fault of the speed probe and send an alarm in advance to avoid protection failure.
