About the DS3800HXTA1E1F
The DS3800HXTA1E1F printed circuit board by General Electric was developed as a Series 6 Transmitter. This fits into the Mark IV Speedtronic system. The Mark IV was designed for gas and steam turbine control and can be used to sequence turbine systems and their auxiliaries for a fully automated startup as well as for shutdown and cool down protocols. The Mark IV was designed with triple-redundant sixteen-bit microprocessors and integrated chipsets utilizing 'controlled failure' technology to maximize uptime and running reliability of the system as a whole.
The DS3800HXTA1E1F has forty integrated circuits, including quad differential line receivers made by Texas Instruments that are built with complementary output-enabled inputs and low power Schottky circuitry. These receivers (AM26LS33ACN) meet or exceed the requirements of ANSI TIA/EIA-422-B. It has also been designed with integrated line drivers.
The DS3800HXTA1E1F is marked along one edge for help with alignment. It is factory-drilled to give the user mounting options and comes with two inserter/extractor clips attached to two corners. There is a line of spare PTH (plated through holes) located near the center of the board.
The DS3800HXTA1E1F includes two LEDs along one edge. These are marked 'parity ok' and 'chain ok.' It has one TP test point along this same edge. There are two connectors (one male and one female) for communicating with other PCBs. It also has five resistor networks.
Before attempting installation of the DS3800HXTA1E1F it is best to review installation guidelines as shown in technical support publications from the original manufacturer, such as data sheets and manuals.
