Electronic Overload Relay
The Allen-Bradley E300 electronic overload relay integrates communications, including EtherNet/IP, current-measurement technology and time-saving I/O options, all in a modular design. The modularity provides users with the flexibility to tailor the device to meet their exact needs, enabling their motor-driven processes to perform more efficiently and profitably. The device's native dual-port EtherNet/IP option simplifies network wiring by allowing it to be daisy-chained and by eliminating the need for an Ethernet switch. It also provides an embedded Web server, which allows maintenance personnel to use a simple Web browser to integrate the overload relay from any Internet-enabled device without the need for special software. To maintain uptime in the event of a network node interruption, the unit supports a device-level ring (DLR) network topology.
