Intelligent L2 Switch Series for Industrial Use

Developed by Hitachi, intelligent L2 switch for industrial use that combines long life (a 10-year design life) and advanced functions with excellent reliability and durability.
In addition to more than 40 routine functions, including support for the simple network management protocol (SNMP) and spanning tree protocol (STP), the switch also uses a proprietary ring topology based on the core technology from the control network [International Electrotechnical Commission Publicly Available Specification (IEC PAS) 62953]. In configurations of up to 64 devices, functions for improving reliability include automatic recovery from network faults in less than 500 ms, route switching in response to intermittent as well as persistent faults, and duplication of blocking locations.

Other features are as follows.
(1) It is resistant to dust thanks to a housing that does not include a fan or ventilation slots.
(2) It has 4G resistance to vibration [and also complies with class 1 of Japanese Industrial Standards (JIS) E3014].
These three features make the switch suitable for installation on machinery that is exposed to harsh environments.
