Actelis: ML684DFT/P Industrial Ethernet Switch/Extender

Industrial Ethernet Switch and Extender

The ML684DT/P Industrial Ethernet Switch and Extender from Actelis is a small form factor Add-Drop unit enabling the delivery of symmetrical high-speed Ethernet services over existing copper and fiber infrastructure. Up to 60 Mbps of symmetrical Ethernet traffic over copper and 1 Gbps over fiber. The ML684DT/P offers an integrated serial server functionality supporting existing legacy devices. The ML684DTP provides also PoE+ interfaces feeding two remote devices such as advanced cameras for security and surveillance applications.

Integrated serial server functionality supports existing legacy devices

Designed for Industrial, utility and traffic applications, The ML684DT/P takes in two fiber ports and/or four copper pairs and allows them to be split into two directions, east and west, thereby allowing multiple nodes to be connected over copper or fiber in a linear chain, RSTP/STP mesh or ERPSv2 ring configuration. Each node has full switching capabilities and can drop and add Ethernet traffic at each location while transferring the rest of the traffic through.
The ML684DT/P offers extremely small factor and DIN rail mounting for flexible deployment within utilities, traffic and industrial cabinets. With its superior performance, extensive functionality, high robustness and reliability, the ML684DT/P Ethernet switch offers rapid service delivery and allows for complete utilization of the existing network infrastructure.
