Self-Healing Ring Industrial Switch

The Loop-IP6820 is a gigabit Ethernet self-healing ring network termination unit (NTU). The layer 2 switch supports the very efficient ERPS G.8032 Ethernet Ring Protection. For ring topologies the IP6820 supports auto-discovery to discover up to 128 units on the ring as well as remote configuration for easy installation.

All end devices can be in packet format via Ethernet ports or serial data via RS232/422/485 interfaces, which are converted into packets within the IP6820. The device has two WAN optical interfaces, two LAN optical interfaces, four electrical LAN interfaces, and one alarm relay interface. Manufacturing options include four additional electrical LAN interfaces, four or eight RS232/422/485 interfaces, and two sets of Dry in/out interfaces.
