Product Description

The IS200EXAMG1BAA is a PCB board component made to work with the Mark VI system from GE.  In production since the late 19620s, the Mark VI is part of the Speedtronic line that has been GE’s premiere industrial turbine management system focused on hydro/gas/steam applications.  When the Mark VI was released in the 1990s, it had the advantage of research based upon the development of earlier systems in the Speedtronic catalog.

The IS200EXAMG1BAA is used as an Exciter Attenuator Module.  This module works together with the EGDM board as a field ground detector to protect the system’s generator shaft.   Together, these two boards can detect any ground paths from exciter components that may be present. The IS200EXAMG1BAA acts to drive the electrical center of the field winding with a low-frequency ac voltage relative to ground.  

The IS200EXAMG1BAA is built with two female connectors, including one female 3-position plug (J1) and a female nine-position cable connector (J2) that is also labeled “Ground Detector.”  The circuit card has one screw connection for the use of surface wiring (TB1,)  three jumper switches, and two stab-on connectors.  The stab-on connectors are labeled E1 (Vbus-p) and E2 (Vbus-n.)  It also has two metal oxide varistors, one relay, four large capacitors made from polyester vinyl, twenty wire-wound resistors as well as resistors of other material.   The board ID number and manufacturer’s logo are both present on the board’s surface.  

Our team will carefully pack your order for shipping, including the use of anti-static wrap to protect from electrical discharge.   Please follow all manufacturer safety procedures as published in manuals and data sheets during the installation process.
