Allen-Bradley 193-ECM-ETR Ethernet IP Communications Module

The Allen-Bradley 193-ECM-ETR Ethernet IP Communications Module is a two-port EtherNet/IP interface designed for Allen-Bradley E300 overload relays, providing the network bridge between E300 protection devices and a Rockwell Automation control system. It serves as the EtherNet/IP communication module for E300 relays, enabling data exchange with EtherNet/IP scanners such as Logix controllers and other Ethernet/IP devices, while supporting two independent Ethernet ports for path diversity on the network. This module is the replacement for the older 193-ETN, and it includes Device Level Ring (DLR) style network functionality to improve Ethernet network resilience in motor protection applications. IP configuration is straightforward, with the ability to set the address (for example, 192.168.1.xxx) to integrate into standard industrial networks. The 193-ECM-ETR is specifically used with E300 overload relays (193/592 IEC/NEMA), delivering reliable, two-port EtherNet/IP communications within a Rockwell Automation ecosystem for monitoring, control, and status reporting.
