The IS200EISBH1A model is an Exciter ISBus board that is part of the EX2100 Series produced by General Electric. This board specifically is a special communication interface board and is used in conjunction with the C, M1, and M2 control modules. Another function of the module is to transmit and receive fiber-optic signals through the backplane connector. There are six fiber-optic connectors that are on the front panel, and the generator field on the panel accepts current and voltages.
The IS200EISBH1A board transmits the feedback that it has received over the backplane controller to the DSPX control, it will also communicate between the tool and keypad ports using RS-232C and the DSPX module. This module typically will manage all of the fiber-optic communications throughout the cabinets. Physically the EISB module is a 3U high module, as well as a single slot. Part IS200EISBH1A will also transmit signals to the ground detection module (EGDM).
The best manual to use for installation procedures and data on how the IS200EISBH1A module works you can view the GEH-6632 EX2100 Excitation Control User’s Guide, information on the EISB board can be found on page forty-eight. Another manual that is best used with the IS200EISBH1A module is the GEI-100454 manual.
