GE IS200VTURH1A Vibration Transducer Interface Module

Part Number IS200VTURH1A Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI Function Module Availability In StockIS200VTURH1A is a VME Turbine card developed by General Electric under the Mark VI series. GE's successful Speedtronic range includes numerous gas-and-steam turbine management systems, including the Mark VI. The TMR architecture was used for the third of these systems. The system's dependability and precision are considerably improved by using three independent and separate IONets, Control TMR Modules, and power supplies. 

General Electric invented this type of control system in 1983. This VME protects primary turbines and the functions include: To create the primary Overspeed trip, four passive pulse rate devices are used to measure the turbine speed. Induced shaft current and voltage are being monitored. Automatically synchronizing the generator and shutting down the main breaker. Three principal Overspeed trip relays are controlled. The TRPx terminal board contains these. 

 Over sixty integrated circuits are present on the board surface. IDT 7024 S35J Dual-Port Static RAM and IDT 71016 S15Y CMOS Static RAM are among the Xilinx Spartan XCS40 field-programmable gate arrays. There are several diodes, resistors, and capacitors on the board, as well as inductor coils/beads (L1 through L16) and more than a dozen transistors. Two backplane connectors and a female plug for connecting a daughterboard are included on the board. Three screws are used to connect a faceplate to the leading edge. A single cable connector (J5) and three LED components make up this faceplate. 94V-0 and 6BA01 are the codes on the board.

FUNCTIONAL DESCRIPTION:

IS200VTURH1A is a Vibration Transducer Interface Module manufactured and designed by General Electric as part of the VI Series used in GE Speedtronic Gas Turbine Control Systems. Measures the turbine speed with four passive pulse rate devices and passes the signal to the controller, which generates the primary overspeed trip. Provides automatic generator synchronizing and closes the main breaker. Monitors induced shaft voltage and current. Monitors eight Geiger Mueller flame detectors on gas turbine applications. The detectors are connected to TRPG and use 335 V dc, 0.5 mA from an external supply. Controls three primary overspeed trip relays on the TRPG terminal board. The controller generates the trip signal, which is sent to VTUR and then to TRPG to trip the emergency solenoids. The turbine overspeed trip can come from VTUR or VPRO. TRPG contains nine magnetic relays to interface with three trip solenoids, known as Electrical Trip Devices (ETD). Nine relays are used in TMR systems and three in simplex systems.

OPERATION:

In the simplex application, up to four pulse rate signals may be used to measure turbine speed. Generator and bus voltages are brought into VTUR for automatic synchronizing in conjunction with the turbine controller and excitation system. TTUR has a permissive generator synchronizing relays and controls the main breaker relay coil 52G. Shaft voltage is picked up with brushes and monitored along with the current to the machine case. An interface is provided for four passive, magnetic speed inputs with a frequency range of 2 to 20,000 Hz. Using passive pickups on a sixty-tooth wheel, circuit sensitivity allows detection of 2-RPM turning gear speed to determine if the turbine is stopped (zero speed). If automatic turning gear engagement is provided in the turbine control, this signal initiates turning gear operation.

PRIMARY TRIP SOLENOID INTERFACE:

The normal primary overspeed trip is calculated in the controller and passed to the VTUR and then to the chosen primary trip terminal board. TRPx contains relays for interface with the electrical trip devices (ETD). TRPx typically works in conjunction with an emergency trip board (TREG) to form the primary and emergency sides of the interface to the ETDs. PTUR supports up to three ETDs driven from each TRPx/TREx combination. There are several different trip boards supported by VTUR.

TRPG is targeted at gas turbine applications and works in conjunction with TREG for emergency trips. TRPS is used for small and medium-sized steam turbine systems and is controlled by the PTUR I/O pack. TRPL is intended for large steam turbine systems and is controlled by the PTUR I/O pack for emergency trips. Additional trip boards are being developed for other specific applications. In support of the trip board operation, VTUR provides several discrete inputs used to monitor signals such as trip relay position, synchronizing relay coil drive, and ETD power status.
