DS3800NAID1E1D

Product Description

GE’s DS3800NAID1E1D is a PCB component designed to fit into the MKIV gas and steam turbine management system. GE introduced the MKI, their first Speedtronics system, in 1968. The MKIV developed roughly a decade-and-a-half later. The MKIV had significant technological improvements compared to the earlier MKI and MKII. One of these improvements, the addition of multiple computer platforms to run the turbine’s protection parameters and critical controls, had a major impact on reliability and outage rate.  Since the MKIV will not proceed with major decisions until two of its three linked computer systems agree, reliability increased and turbine outage rate decreased. The MKIV protects the turbine from issues like high pressure, vibration, and loss of flame.

The DS3800NAID1E1D has very few components.  Primarily used for communication, the board has ten mating connectors on its surface, all of which are vertical pin male connectors.  Five of these are placed on the bottom edge of the board, while four are located near the top edge. Each of these is marked with sub-labels such as PULSE, RATE, LOOP, LINE, IN, and OUT. The board also has many test points.  These are marked HI, LO, ACOM, LINE PULSE RATE, and LINE OUT.

The DS3800NAID1E1D has resistors, diodes, and capacitors on its surface. It is built with a set of spare PTH.  The board has two push-button switches, which are located side-by-side.

The DS3800NAID1E1D will be received at your facility in a static reducing plastic sleeve or covering.  GE provided tech support for this part, including manuals and data-sheets.
