The RocketLinx ES8108 is Pepperl+Fuchs Comtrol’s 8-port Fast Ethernet industrial switch featuring a 2.0Gbps Packet Switch engine with packet forwarding and filtering mechanisms to meet industrial communications standards. It provides packet forwarding capabilities to handle 64 to 1552 byte long packet sizes in two priority queues to optimize data forwarding performance. Broadcast storm filtering and flow control functions ensure data delivery free of traffic congestion.

For installation in hazardous or industrial environments, the RocketLinx ES8108 is equipped with two redundant power inputs, features wide input voltage ranges, and operates within a broad -34° to 70°C temperature range. For ease-of-maintenance, the RocketLinx ES8108 has one alarm relay for port link and power events to assist engineers with on-site notifications.

RocketLinx Reliability

The RocketLinx ES8108 has dual power inputs, and can also operate on 12 to 48VDC. Dual power inputs and built-in reverse power polarity protection are designed as the redundant power system to ensure power continuity. With the 1.5KV Hi-Pot isolation protection, CE/FCC/UL regulatory approvals, and a 5-year warranty, the RocketLinx ES8108 is the ideal switch solution for industrial and hazardous environments.
