Overview
Introduction
The 8-port M12 IP40 unmanaged industrial switch is a rugged device to
be deployed in various environments. The Ethernet switch conforms to
EN50155, EN50121-3-2, EN50121-4 railway applications standards.
Heavy Duty
Designed with circular M12 connectors and constructed with metallic
housing, the Ethernet switch provides the rugged Fast Ethernet
interface to withstand vibration and shock.
Dual Power Inputs
The redundant power input design for the Ethernet switch gives a
backup power solution. With both the power inputs supplied, if either
one fails the other one will be activated to keep the system operating
continually.
Flexible Mounting
The Ethernet switch is compact and can be mounted on the wall, and it
is suitable for any space-constrained environment.
Bypass Function
The equipment is designed with the function known as Bypass. When
the power failure occurs, a shorted circuit between two Ethernet ports
(P1 and P2) is formed to have the equipment being a bypassed device
to prevent the network from disconnecting.
