This network switch for industrial use is optimized for performance. The aluminum housing with an IP-31 protection rating is suitable for mounting on a DIN rail. The power supply is dual (redundant power supply) and is provided via a terminal block, which can be easily disconnected in case of service. Additionally, a relay contact for warning purposes can be tapped from the terminal block. If needed, any of the 8 ports can trigger an alarm in the event of a link failure. The power supply can also be monitored. Configuration is done via DIP switches.
