Chapter 1 Product Overview
Control Module
Figure 2 - Control Module
The control module is the heart of the E300 Electronic Overload Relay and can
attach to any sensing module. The control module performs all protection and
motor control algorithms and contains the native I/O for the system. The control
module has two varieties:
• I/O only
• I/O and protection (PTC and External Ground Fault Current Sensing)
The control module is offered in three control voltages:
• 110…120V AC, 50/60Hz
• 220…240V AC, 50/60Hz
• 24V DC
External control voltage is required to power the E300 Electronic Overload Relay
and activate the digital inputs.
Communication Module
Figure 3 - Communication Module
The communication module allows the E300 Electronic Overload Relay to be
integrated into an automation system, and it can attach to any control module.
All communication modules allow you to set the node address with rotary turn
