DS4815DTDB

Product Description

The DS4815DTDB is a PCB from GE manufactured for the Mark IV series.  The MKIV was developed by GE to manage gas and steam turbine systems. It replaced the earlier Speedtronic series from GE, like the Mark I and Mark II, with improved reliability and a lowered turbine outage rate, primarily due to its use of multiple microprocessor-run platforms to run all critical controls and parameters.

The DS4815DTDB is built with a single toggle switch next to a single red LED.  It has one female mating connector located along an entire short edge.

The most notable components on the DS4815DTDB are four very small auxiliary boards.  These each connect to the board using thirteen board-to-board metal pins. Each board also has a line of additional board-to-board pins located next to it. Parallel to each board on one side is a line of eight jumper switches. On the other side, there is a resistor network placed next to each auxiliary board.  

The DS4815DTDB has one transistor, thirty-seven jumpers (including those already mentioned above,) eleven resistor networks (again, including those already mentioned,) and forty circuits.  Circuits include two-input positive OR gates, oscillating chips, octal buffers and line drivers, and CMOS static RAM.

The DS4815DTDB is marked with an identification number.  It is drilled at each corner and has extractor clips installed.  Extractor clips give technicians a lever point to push a board out of a frame or chassis.  It also provides them with a handle if needed, so they do not have to touch components or circuitry on the board.

A static-reducing sleeve will be used to protect the DS4815DTDB during shipping.  Technicians should review any and all datasheets/manuals referencing this part before installation. All technical support for the DS4815DTDB was originally provided by GE.
