IS200STURH4A is a simplex input terminal board developed by General Electric. This module is a part of the Mark VIe Series used in GE Excitation Systems. The Simplex Primary Turbine Protection Input (STUR) terminal board is a simplex S-type version of the turbine terminal board (TTUR). It offers a connection for the turbine-specific primary trip (PTUR), speed and synchronization inputs, trip relay outputs, and a cable to control a primary trip board. STUR is used for the following:
There are four different configurations of STUR available. With fixed box terminals, STUR is not possible. It makes use of pluggable connections. For employing an external trip board, two groups provide DC-37 pin connectors and two groups provide onboard trip relays. Two groups utilized for mechanical applications will have components removed, while groups used for generator applications will have more components added.
Four-speed input circuits are offered by STUR and can accommodate either passive or active speed sensors. Signal application for passive sensors occurs between terminals PR# H and PR# L, where # is one through four. The PTUR I/O pack can detect speeds as low as 2RPM thanks to the passive sensor input's sensitivity. Signal application occurs between terminals TTL# and PR# L when active speed sensors are being used.
Two trip solenoid outputs, K1 and K2, are provided by STUR versions H1 and H2 and are each made up of a safety relay that makes use of forcibly steered contacts. PTUR receives relay position info from one of the relay's contact pairs. To link two or three STUR boards in a redundant tripping arrangement, additional customer terminals are offered.
What is IS200STURH4A?
It is a simplex input terminal board developed by General Electric
What is the purpose of the STUR terminal board?
The STUR terminal board is used to provide over-speed protection and primary synchronization for mechanical drives and generator drive systems. It is also used in other applications that require the four pulse input circuits of PTUR.
What is the difference between STUR and TTUR terminal boards?
The STUR terminal board is a simplex S-type version of the turbine terminal board (TTUR). While both terminal boards provide connections for turbine-specific inputs and outputs, the STUR terminal board is specifically designed for applications that require over-speed protection and primary synchronization, while the TTUR terminal board is designed for more complex turbine control applications.
What types of applications can use the STUR terminal board?
The STUR terminal board can be used in mechanical drives that require over-speed protection, generator drive systems that require over-speed and primary synchronization, and other applications that require the four pulse input circuits of PTUR.
