1. Product Introduction, Brand & Series
Brand: GE Fanuc (General Electric)
Series / Platform: EX2100 Excitation / Mark VI / IS200 Exciter Controller Systems
Product Overview:
The IS200ERBPG1A is an Exciter Regulator Backplane Module (ERBP) used in generator excitation control systems. It serves as the backplane interface that supplies power, connects keypad and control connectors, and links together various cards/modules in the EX2100 / Mark VI excitation regulator system. It ensures proper distribution of positive and negative power through terminals labelled TB1 (positive) and TB2 (negative), provides multiple plug / connector interfaces (keypad, three‑position connectors, twelve‑position plug), and supports both simplex and redundant configuration modes.
