Description

The IS200JPDHG1A is a component created by General Electric for their Mark VI system.The MKVI was one of the last systems released by GE under the Speedtronic name. For several decades Speedtronic systems like the Mark I, the Mark IV and the Mark VI were considered to be some of the most reliable gas or steam turbine management systems available.When the Mark VI was released it had over three decades of research and development behind its design. This system includes a central Control Module that is responsible for the majority of control, protection, and monitoring of the turbine system. The IS200JPDHG1A functions as a High-Density Power Distribution Board.This board may be used for one Simplex or for three independent control power buses fed power (RST.)This is based on the cable harness feeding supply to J1. Refer to GE publication GEI-100861 for wiring information. The IS200JPDHG1A is often used with the following GE cables: 336A5026JBG077 from a JPDG J1-J4 control power output, for control power supply to JPDH J1 336A5026EHG0yy to daisy chain JPDH boards together (J1X to J1) 336A5026EFG0yy to connect JRS, JS, or JTS to IONet Ethernet switches 336A5026RDG0yy I/O pack power that is fed by JR1-8, JS1-8, or JT1-8. TheIS200JPDHG1A is built with two 6-position plugs (J1/J1X,) three 2-position plugs (JR5/JS5/JT5,) and twenty-four 2-position plugs (JR1 through JR8, JS1 through JS8, and JT1 through JT8.)The board also has twenty-four varistors that line up with the 2-position plugs (TRR1 through TRR8, TRS1 through TRS8, and TRT1 through TRT8.)
