IS200VTURH1BAA GE MKVI, VME Turbine Card-colletplc

Description:

IS200VTURH1B is a VME Primary Turbine Protection Board developed by GE. The board monitors shaft current/voltage (with alarms for excessive levels), measures turbine speed to generate the primary Overspeed trip, and controls the three primary Overspeed trip relays on the TRPx terminal board. The board also monitors eight Geiger-Mueller flame detectors.

The component has a single-slot faceplate with three LED indicators and a single cable connector that is connected (J5.) Three screw connectors link the faceplate to the PCB.
Over sixty integrated circuits, thirteen transistors, hundreds of capacitors and resistors, as well as diodes and inductor coils, make up the PCB.
Two backplanes, a female multi-position plug for connecting a daughterboard, and various connectors made of conductive dots and traces are all included on the board.
The card includes one TRPx board to drive three trip solenoids, accepts eight flame detectors, and stores the pulse rate in digital circuitry. VTUR detects high voltages and checks the circuitry's integrity and continuity.
For speed control and the primary overspeed trip signal, the median speed signal is employed.
Four passive magnetic speed inputs with a frequency range of 2 to 20,000 Hz interface with VTUR. Circuit sensitivity allows detection of 2-RPM rotating gear speed using passive pickups on a sixty-tooth wheel to determine if the turbine is stopped (zero speed). This signal starts turning gear operation if automatic turning gear engagement is enabled in the turbine control.
