About the DS38600HCVA

DS38600HCVA D/A Output Card Mark IV 

The DS38600HCVA is a GE Digital to Analog Output board designed for use within the Mark IV Speedtronic system.  The Mark IV significantly improved reliability over its precursor, the Mark II, through the use of a new type of control architecture. This control design, which came to be known as TMR/triple modular redundancy, was a breakthrough in the design of gas and steam turbine control systems that has been repeated by multiple systems since. 

The DS38600HCVA has a long backplane connector (female) along one edge of the board.  On the other short edge, there is a very small male right-angled connector with two clips.   This edge is populated by two amber LED indicators and two relays.  It also has several TP test points and two extractor clips inserted into the corners of the boards.

The largest components on the surface of the DS38600HCVA are two general purpose DC/DC converters.   These modules have pi input filters that minimize reflected ripple current and a minimum efficiency of 61%.  Their output voltage accuracy is +/- 1%.  The components are large enough to need secondary support to the board in the form of zip ties.    Other components include three potentiometers, over a dozen jumper switches, fourteen transistors, as well as over twenty integrated circuits.  The board has resistor network arrays, resistors, diodes, and capacitors.   The board is marked along its edge to help with alignment and carries codes like 6BA06 and CESS.  The top surface of the board is cut away in several places to show the underlayment.
