Description

The DS3800NTBL is manufactured by GE for their Mark IV series. This system is designed to manage gas and steam turbines. It is built to minimize downtime through its built-in redundancies on all critical controls and parameters, which allow the system to shift control as necessary.

The DS3800NTBL is made to function as a bus terminator card. These cards may help improve signal quality in networks that don’t already have termination networks installed. It may prevent reflections that can cause communication failure caused by oscillation. These standing waves and reflections may interfere with the proper operation of system cards and the proper operation of the computer.

The DS3800NTBL is a small card with very few components. It has two mating connectors, which are both vertical male connectors. The connector labeled JA has twenty-six pins. The connector labeled JB has twenty pins.

There are two codes embedded on the edge of the DS3800NTBL; these are 6DA00 and 6BA00. The board is drilled in all corners. It is marked with four arrows. In between two of these is the term “O-True,” and in between the other two is the term “1-True.”

The DS3800NTBL has been marked and labeled for twenty-three resistors. It is worth noting only twenty metal film resistors populate the board. R12, R22 and R23 have PTH and wiring, but no component. The labels for resistors, starting with R1 are A0, A1, A2, A3, A4, A5, A6, A7, RS, WS, RST, DAK, STB, D0, D1, D2, D3, D4, D5, D6, D7, FSR, and ASR.

General Electric was responsible for all technical support for the DS3800NTBL. The original manufacturer published all reference material for this part, including manuals.
