The DS3800HITA1F1F is a printed circuit board from GE. The DS3800HITA1F1F is designed as a component-part in a Speedtronic Mark IV gas and steam turbine control system. The Mark IV was designed with intentional redundancies built between chipsets to increase reliability and to 'build in' a controlled failure/recovery system. This keeps downtime caused by electronics failure minimized and run-time maximized.
The DS3800HITA1F1F has 34 integrated circuits, including EPROMs, DIP components, and oscillators. It has seven jumper switches that allow the user to choose between A/B, on, off, and short, long. The board is populated with multiple small capacitors as well as metal film resistors of differing values.
The DS3800HITA1F1F has been factory drilled in all four corners. It has been marked for alignment using letters (A through J) and triangular markings along its top edge. The codes 6DA03 and 6BA06 appear along its bottom edge.
The DS3800HITA1F1F has been designed with nine LEDs located along its upper right edge. Eight of these are numbered (0-7) and one is labeled 'Imok." The numbered LEDs are red, and the other LED is amber. There is a row of test points located below the LEDs. These are either numbered (1-7) or labeled: tp8-ox. tp9-va. tp10-vb. tp11-vc. tp12-out0. tp13-out1. tp14-out2. tp15-dcom.
The DS3800HITA1F1F has 4 resistor network arrays. It has one long AMP connector (218A4553-1) along one edge.
Technical support, including data sheets and manuals, for the DS3800HITA1F1F was originally provided by GE. These publications are excellent references for installation instructions and safety precautions.
