About the IS200VPWRH1AGB

The IS200VPWRH1AGB is a PCB component created by GE for the Mark VI system.  The Mark VI is one of many gas/steam turbine management systems released by GE over the last few decades as part of their Speedtronic line that began in the 1960s.  The Mark VI is powered by a 125V dc battery system that is external to the control. The Mark VI can also use a 120/240V ac source that has been rectified to 125V dc.  The ‘internal’ 125V dc is fuse-isolated within the MKVI power distribution module. From there, it is fed to internal power supplies.

The  IS200VPWRH1AGB is a daughterboard/sub-assembly of the IS215VPROH215 board; this is the top board of the assembly.  The IS200VPWRH1AGB connects to the rest of the assembly using four screws mounted through factory-drilled holes and threaded through standoffs.  The IS200VPWRH1AGB connects at three points to the front faceplate.

The  IS200VPWRH1AGB has four connectors or plugs.  These include a 3-position female plug located toward the back of the board that wires into a 3-position power plug mounted into the front faceplate.  The wiring occurs on the surface of the board. The board also has a single right-angled cable connector on its front edge that mounts into the front panel.  The other two connectors are 64-position female plugs. It is worth noting the IS200VPWRH1AGB does not include any sort of backplane connector. ​​​​​​​

The  IS200VPWRH1AGB  has multiple LED indicators.  This includes stacked red and green LEDs located on the front edge, as well as a line of green LEDs stacked above clear LEDs.  These indicators all mount into the front faceplate and are labeled.

The surface of the  IS200VPWRH1AGB is populated with a single heat sink component.  It has transistors, a transformer, test points, capacitors, resistors, diodes, and integrated circuits.
