Description

GE  IC693ACC332  control module

Functional features: As a component of the gas and steam turbine controller, it undertakes multiple important functions, including controlling the operation of the turbine, limiting the system output within the capacity of the device, performing relevant operations on control parameters during the startup process, providing protective shutdowns in the event of irreversible system failures, and monitoring and reporting faults in the control system. It is also responsible for monitoring the auxiliary equipment of the turbine, etc. For instance, the speed controller (governor) of a gas turbine can adjust the speed of the turbine output shaft. The speed control feature can be either an isochrone speed (maintaining the speed at the set value regardless of the load) or a descent speed with the load (droop control), to adapt to different application scenarios, such as generator drive applications or mechanical drive applications, etc.

Circuit composition: This module consists of two integrated circuits and four transistors. Both circuits are four-comparators and feature low power consumption and low offset voltage. In addition, there are four light-emitting diodes (CR1 to CR4) and 32 jumper switches. Each jumper provides users with two ways to complete the selection of each circuit. The board has a right-angle male connector (numbered 218A4637P2), and on the other side, there are twenty-five metal pins. Below the pins, there are numbers ranging from ten to fifty for connecting the circuit board to the wiring of the Mark I/II frame. There are also four relays on the surface of the module. And polyester vinyl capacitors and capacitors of different materials were used to construct this board, and there were also multiple rows of resistors and diodes on the board.
