DS3820MAUC

Product Description

The DS3820MAUC is a modified PCB designed as a component for the Mark IV system.  This system is made for the management of gas and steam turbines, and is built around integrated microcomputers that monitor the turbine system twenty-four hours a day, and protects it from such things as fire, vibration, over speed, and loss of flame.  The MKIV can also automate such procedures as startup, speed control, control sequencing, and shutdown.

The DS3820MAUC is a modified version of the DS3800HRPB.  There are several modifications that have taken place. These include the installation of a top hat mounting plate with two slots cut into each short end.  This mounting plate is attached to the PCB by screws placed through factory drilled holes at each top corner of the board and near each bottom corner. These locations also support vertical spacer pins in which a plexiglass shield is connected.  This plexiglass shield is another modification. A fifth support is added at the center of the board. The final modification to the board is the addition of a cable connector bar. This bar allows for the connection of eight cables via eight round cable ports.  

The original board (DS3800HRPB) is built with a board stiffener running across its long dimension.  The board has eight toggle switches and a set of spare PTH. The board has one transistor, a six-pin header, and many integrated circuits, including oscillating chips.  Resistors tend to be ceramic-covered metal film. There is one thermistor located on the board. Capacitors are made of several materials.

Technical support for the DS3820MAUC was provided by GE.
