FUNCTIONAL DESCRIPTION:

IS210TRESH1A is a Steam Turbine Emergency Trip Terminal Board manufactured and designed by General Electric as part of the VIe Series used in GE Distributed Control Systems. The steam turbine emergency trip terminal board is a crucial component in the control and safety system of steam turbines. This board serves as a central interface for emergency shutdown signals, which are activated in critical situations to safeguard the turbine and associated equipment from damage or malfunction. In the TRES, the seven dry contact inputs excitation and signal are monitored and fanned to the protection module. The board includes the synch check relay driver, K25A, and associated monitoring, the same as on TREG, and the servo clamp relay driver, K4CL, and its associated monitoring. A second TRES board cannot be driven from the protection module.

A maximum of three trip solenoids can be connected between the primary and emergency trip terminal boards. Connecting a solenoid between the boards isolates the power on both sides of the solenoid as well as the visibility of solenoid voltage as a system feedback. The primary/emergency trip boards TRPG/TREG, TRPL/TREL, and TRPS/TRES are designed to operate as a pair and use cabling between the boards for system connections. TRPA and TREA are designed with no pairing required and can be used independently of each other. When TRPA and TREA are paired, they function the same as other board pairs.

FEATURES:

Emergency Shutdown Inputs: These terminals receive signals from various sensors and instruments monitoring critical parameters such as turbine overspeed, low oil pressure, high vibration, or abnormal temperatures. When any of these parameters exceed safe operating limits, the corresponding input triggers an emergency shutdown.

Interlocking Mechanisms: The terminal board may incorporate interlocking mechanisms to ensure proper sequencing of shutdown procedures and prevent unintended activation or bypassing of safety measures.

Relay Logic: Relays on the board provide the necessary logic for processing incoming signals and activating the appropriate shutdown mechanisms. They often feature fail-safe designs to ensure reliable operation even in the event of power loss or other system failures.

Alarm Indicators: Visual and/or audible alarm indicators may be integrated into the board to alert operators of an impending emergency shutdown and facilitate timely response.

Communication Interfaces: Some advanced terminal boards may include communication interfaces for transmitting shutdown signals to a central control system or remote monitoring station, allowing for quick response and coordination in emergencies.
