About the DS3820PSFF1A1A

The DS3820PSFF1A1A is an AC Input Module designed for the Mark IV series by GE.  The MKIV replaced the MKI and MKII in 1982 as General Electric’s primary gas/steam turbine management system.  It introduced the idea of distributing control functions across multiple platforms run by microprocessor. These platforms (dubbed R/S/T) continuously monitor turbine performance around the clock and make adjustments as necessary.  

The DS3820PSFF1A1A is a modification built around several DS3800 boards.  The AC Input module has a metal housing that is made up of multiple parts connected together using drilled out points and screws.  The metal housing is designed with openings to allow for heat dissipation. These openings also give technicians access to the components with the housing.   

Three components have been mounted directly to the metal housing of the DS3820PSFF1A1A.  These components include a circuit breaker, a fuse, and a four-pin female plug. While most of the boards used in this module are mounted inside the frame, the DS3800XTFP board has been screwed to the exterior.  This board has eight twelve-pin connectors and one six-pin header.

The boards within the frame of the DS3820PSFF1A1A are mounted both vertically and horizontally.  Components may be mounted upwards or downwards. Components included on interior boards include LEDs, integrated circuits, transistors, jumper switches, male and female PCB connectors and headers, toggle switches, test points, heat sinks, high current inductors, transformers, potentiometers, and resistors and capacitors of various size and material.  This includes electrolytic through-hole capacitors of large size.
