DS3800NTEA Series Mark VI/VIe function module

DS3800NTEA Series Mark VI/VIe function module

Part Number DS3800NTEA Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI/VIe Function Module Availability In StockDS3800NTEA is a termination board and is part of the GE Speedtronic Mark IV gas turbine control systems. The DS3800NTEA is a single-circuit device. The circuit is a 20-lead tiny outline package with an octal 3-state buffer/line driver/line receiver. It's an EIAJ Type II with a width of 5.3 mm. PNP inputs reduce DC stress on bus lines, and propagation delay periods are typically 10.5 ns inverting and 12 ns non-inverting. Two rows of spare PTH are available on the terminal board. Plated-through holes, or PTHs, allow components to make contact with the board's electrical layers. The board is made up of fixed vacuum capacitors as well as different types of capacitors. Ceramic-covered metal film resistors are the most common, however, carbon composite resistors have also been employed.TERMINATION BD

About the DS3800NTEA

The DS3800NTEA is a termination board by GE created for the Mark IV system.  The MKIV is GE’s steam/gas turbine management system with dedicated control that takes care of startup, speed control, temperature, GT protection, control sequencing, shutdown, and power supply.  The MKIV was an improvement over earlier GE systems, as it has increased reliability and a substantial decrease in the GT outage rate through the use of distributed control functions, as well as having an enhanced operator interface.

The  DS3800NTEA is built with a single circuit.  The circuit is an octal 3-state buffer/line driver/line receiver with 20-lead small outline package.  It is an EIAJ Type II that is 5.3 mm wide. This chip has PNP inputs that reduce DC loading on bus lines and has typical propagation delay times of 10.5 ns inverting, 12ns non-inverting.  

The  DS3800NTEA is built with factory alignment markings along one edge. It is imprinted on one edge with the code 6BA00.  It is drilled in all corners and has inserter/extractor clips added. These nylon clips are affixed to the board by two roll pins. They provide ample gripping surface and give the technician a mechanical advantage during extraction by offering a pivot point to pull the board from its seated position.  

The  DS3800NTEA has two rows of spare PTH. PTH, or plated-through holes allow components to make contact with the conductive layers of the board.   The board is built with fixed vacuum capacitors as well as capacitors of other material. Most resistors are made of ceramic-covered metal film, but carbon composite resistors have also been used.  

Technical support for the DS3800NTEA, including manuals and datasheets, was furnished by GE.
