IS200TREAH2A GE TRIP RELAY BOARD AEP Emergency

Description:

IS200TREAH2A is a Turbine Emergency Trip Terminal Board developed by GE. It is a part of Mark VIe control system. The turbine emergency trip terminal board, is an integral component within the Mark VIe system, specifically designed to collaborate with PPRO turbine I/O packs.

Features
Customer Input Terminals: Accessible through two 24-point pluggable barrier terminal blocks (H1A, H2A) or 48 pluggable Euro-style box terminals (H3A, H4A), these terminals facilitate customer inputs.
Passive Pulse Rate Devices: Nine passive pulse rate devices, distributed across three per X/Y/Z section, are employed to sense a toothed wheel, effectively measuring the turbine speed.
Jumper Blocks: These blocks enable the fanning of one set of three speed inputs to all three PPRO I/O packs, ensuring synchronization and redundancy.
Output Contacts: Two sets of output contacts are provided: one set operating at 24 V dc (H1A, H3A), and the other at 125 V dc (H2A, H4A), offering TMR voted output contacts to trip the system in case of emergencies.
Voltage Detection Circuits: Four circuits designed for 24-125 V dc voltage detection are incorporated to monitor the trip string, ensuring system integrity and safety.
Daughterboard Connectors: Additional expansion capabilities are facilitated through daughterboard connectors, offering the potential for optional feature expansion as required.
Voltage Monitors
The trip relays integrated into the board offer flexible placement within a trip string, allowing them to be positioned anywhere along the circuit. To facilitate monitoring and ensure system integrity, incorporates three general-purpose isolated voltage sensor inputs. These inputs serve the purpose of monitoring various points within the trip system and transmitting voltage status information to the system controller, enabling appropriate action to be taken as needed.
Common applications for these voltage sensor inputs include:
Power Supply Voltage Monitoring (PWR): One typical use is to sense the power supply voltage for the two trip strings. Monitoring the voltage levels ensures that the power supply remains within acceptable ranges, crucial for the reliable operation of the trip system.
Solenoid Voltage Monitoring (SOL1, SOL2): Another common application is to monitor the solenoid voltage of the device being controlled by the relays. By monitoring solenoid voltage, the system can ensure that the correct voltage levels are being applied to activate the devices effectively.
While the board symbol may suggest these specific applications, it's important to note that the sensors are versatile and can be applied to various scenarios based on the specific requirements of the application. This flexibility allows for optimal utilization of the voltage sensor inputs to meet the unique needs of the trip system
