Description

The IS200JPDSG1A is built as part of the Mark VI system by GE.The Mark VI is one of the final steam or gas turbine management systems built and released by GE under the Speedtronic” name. The IS200JPDSG1A is a DC Distribution board.This board is constructed to receive 28VDC input power via external dc/dc or ac/dc converters and then distribute this to the control system.This board works with the feedback signal P1 and P2 connectors on the JPDE, JPDF, and JPDB boards. The DC-62 connector (vertical female multipin, marked JA1) on theIS200JPDSG1A board is compatible with the Input/Output pack on IS220PPDA. TheIS200JPDSG1A is built with four varistors, three inductor coils, and two vertical 50-pin diagnostic ribbon connectors.These connectors are marked P1 and P2. P1 transmits feedback signals to a board with a PPDA Input/Output pack. P2 receives feedback from other power distribution boards in the system and passes these signals through the P1 to the PPDA.The board also has six 2-position plugs (JAT/JAS/JAR and JCT/JCS/JCR) which are used as dc outputs and auxiliary power connectors. The board has six 6-position plugs (J1 through J6.) These are used as outputs to JPDP cards. The board has three 9-position plugs (JR/JS/JT) that are used as power supply connectors with a 28V power input.Finally, there is a 2-position plug (P4) that is a power output. The board has two terminal boards (TB1 and TB2.) The board also has various resistors, capacitors, and TP test points. More information on the operation and installation of the IS200JPDSG1A can be found in GE publication GEI-100613.
