TECHNICAL SPECIFICATIONS FOR GE - IS200TRELH1A

IS200TRELH1A is an emergency trip board developed by GE. It is a part of Mark VI control system. It operates in conjunction with the I/O controller within the protection module to execute specific functions vital for turbine safety. TREL serves as a crucial safety mechanism in large steam turbines, specifically dedicated to emergency overspeed protection through its interaction with the I/O controller and control of trip solenoids. Its specialized design in TMR form, devoid of certain features present in other relays like TREG, underscores its focus on emergency functionalities and safety protocols. Additionally, its expandability with multiple boards further emphasizes the importance of redundancy in critical turbine safety systems.

CONTROL MECHANISM

TREL is under the command of the I/O controller, responsible for administering power to three essential emergency trip solenoids. These solenoids are connectable between the

TREL and TRPL terminal boards. TREL supplies the positive side of the 125 V dc to the solenoids, while TRPL provides the negative side.

FEATURES AND CHARACTERISTICS

TMR Configuration Exclusive: TREL is solely available in Triple Modular Redundancy (TMR) form, emphasizing redundancy and reliability in its operational setup.

Absence of Economizing Relay: Unlike its counterpart, TREG, TREL lacks an economizing relay, perhaps to streamline its functionality towards emergency protection without additional economizing features.

No E-STOP Function: In contrast to TREG, TREL does not incorporate an E-STOP function, potentially due to its specialized focus on emergency overspeed protection.

Multiple TREL Boards: The I/O controller possesses the capability to drive a secondary TREL board, enhancing redundancy or extending control over additional components for heightened safety measures.
