DS3800NRCA

Product Description

The DS3800NRCA is a printed circuit board from GE designed as part of the Mark IV series.  The Mark IV was created for steam or gas turbine management and has increased efficiency due to the ability to automate such procedures as start-up and shut down.  The Mark IV’s overall design concept of integrating chipsets and duplicating all critical controls and protection parameters over multiple boards allows the Mark IV the flexibility to continue running even when one individual PCB has an electrical issue.  

The DS3800NRCA’s most notable component is its multiple jumper switches.  Jumpers allow for customization of the board as it gives the user the option to complete circuits as they desire.  Many of the jumpers on DS3800NRCA have multiple settings; for example, J19 may be set to RES, 7in, 12in or 14in.

The DS3800NRCA has three red LEDs placed on its right edge.  Directly above these sits the board’s one trim potentiometer.  Directly below are the board’s seven TP test points. There is also one five-pin right angled mating connector on this edge.   The board has one other mating connector on the opposite edge of the board. This connector is marked 218A4553-1AMP 533002-1.

The DS3800NRCA is built with one through-hole transformer.  This component is marked 782E 3E2A. The board contains one Burr-Brown high current-high power operational amplifier, contained inside a heat sink, and two smaller amplifiers.    It also has one transistor located in the upper left quadrant of the board.

The DS3800NRCA is built with two resistor network arrays.  It has multiple resistors of differing values, made of ceramic-covered metal film and carbon composite material.  

The DS3800NRCA has 26 integrated circuits including octal buffers and line drivers with 3-state outputs and dual d-type positive-edge-triggered flip-flops with preset and clear.

All technical support for the DS3800NRCA including datasheets and manuals originated from GE.
