The Moxa EOM-104 Series is a compact 4-port embedded managed Ethernet switch module designed for device manufacturers who need to add robust networking capabilities to their systems. With a footprint just two-thirds the size of a business card and low power consumption, this module fits perfectly into space-constrained embedded environments such as industrial controllers, smart devices, and communication systems.

The EOM-104 Series supports both 10/100BaseT(X) copper and 100BaseFX fiber interfaces. It features Moxa’s Turbo Ring redundancy technology, ensuring sub-20 ms recovery times, as well as STP and RSTP for enhanced network reliability. SNMP traps, syslog, and email notifications allow real-time network event tracking, while comprehensive MIB support enables seamless integration into enterprise network management systems.
