Product Overview
Chapter 1
Bus Power Supply supplies enough current for a fully loaded E300 Electronic
Overload Relay Expansion Bus (four Digital Expansion Modules, four Analog
Expansion Modules, and one Operator Station). You can use either Expansion
Bus Power Supply with any combination of Digital and Analog Expansion
Modules.
