-
Basic Product Information: Manufactured by General Electric (GE), it belongs to the Mark VI series. It is a turbine emergency trip terminal board with dimensions of 7.0 inches x 13.0 inches and a temperature rating of 0 to 60°C.
-
Function and Purpose: It is mainly used in gas turbine control systems or safety systems, functioning as a trip and emergency shutdown device. When conditions affecting system safety or performance are detected, such as overheating, overspeed, excessive vibration, fuel supply issues, etc., it can automatically or manually shut down the gas turbine.
-
Working Principle: This terminal board supplies power to three emergency trip solenoids in the system. It is fully controlled by the I/O controller, handling the positive pole of the DC power required to operate these solenoids, while ensuring coordinated and balanced power distribution to the solenoids by providing the necessary negative pole of the DC power.
-
Internal Structure: There are two long solid black terminal blocks on the left edge, each containing 24 silver metal terminals. To the right of the terminal blocks, there is a row of approximately 10 circular red metal oxide varistors (MOVs). Most of the space in the middle is occupied by large relays or contactors, arranged in two rows with 6 each. On the right edge, there are three jack connector ports, each containing a set of small pin ports. There are also four large rectangular capacitors on the right side, with two paired in the upper right corner and the other two paired in the lower right corner.
-
Features and Advantages: It includes logic circuits or software for implementing trip conditions, may be equipped with one or more manually operated emergency stop buttons, and provides information such as gas turbine status, trip conditions, and emergency stop operations through indicator lights or other display devices. Adopting a modular design, it offers advantages such as flexibility, maintainability, standardization, scalability, and easy integration.
-
Communication Interface: Although there is no clear information indicating the communication interface of IS200TREGH1BDB, related products in the same series support multiple communication protocols (such as Modbus). It is speculated that this product may also have similar communication capabilities, facilitating integration with other systems.
