DS3800NRTA

About the DS3800NRTA

The DS3800NRTA is a PCB manufactured by GE for the Mark IV gas/steam turbine management system.  The MKIV was introduced by GE in 1982 and replaced the earlier MKI and MKII Speedtronic systems from the 1960s and 1970s.  The MKIV was the first of the Speedtronic systems to use integrated platforms run by microprocessors to oversee turbine system management.  With this innovation, the MKIV saw an increase in reliability and uptime and a marked decrease in the turbine outage rate as compared to those earlier Speedtronic systems.

The DS3800NRTA is factory-drilled in all four corners and lettered on its top edge (A through J) for alignment purposes.  Extractor clips have been inserted into two corners. These extractors can be used as a handle by technicians, and also provide a lever point technicians can use to pull the board out of tight locations during extraction.   The board is marked with the GE symbol and with its board identification number.

The DS3800NRTA has one 218A4553-1 A/mp 102041-1 connector (right-angled, female) to communicate with other boards.  It also has one right-angled male PCB connector with 13-pins.

The DS3800NRTA is built with one jumper switch, fourteen trim potentiometers, and eight transistors.  Potentiometers can be used for voltage division, or to adjust, tune or calibrate circuits. It has twenty-six circuits located on its surface.  

The DS3800NRTA is built with CCR (carbon composite) and ceramic-covered metal film capacitors.  It has polyester vinyl (708D1,) fixed vacuum, and aluminum electrolytic capacitors.

Our warehouse will ship the DS3800NRTA to you protected by a static-reducing sleeve or covering.  All technical support for the DS3800NRTA was provided to the end user by GE.
