Media converters and switches portfolio 'industrial hardened'

20 April 2005 Computer/Embedded Technology

Transition Networks has released a complete line of hardened media converters and switches designed for industrial Ethernet applications. These ruggedised devices are designed to reliably operate in harsh networking environments found on factory floors, outdoor enclosures or other hazardous environments (Class 1/Div. 2). Offered in multiple configurations and connector options, they represent one of the largest unmanaged switch offerings in the industry.

The 10/100 copper Ethernet ports provide full 10/100Base-TX capability and support Auto-Negotiation and AutoCross (automatic MDI/MDI-X) while the fibre ports provide full 100Base-FX capability. The media converter model additionally offers Link Pass Through, which provides the ability to 'pass through' the loss of Rx signal on one of the media ports to the Tx signal of the other media port. In addition, certain models incorporate Redundant Ring technology, which helps increase reliability and system uptime in an industrial automation network by protecting critical communication needs utilising redundant fibre links with switching recovery times of less than 300 ms.

All models offer redundant 12-48 V d.c. power inputs with auto-sensing capability. In addition, dry contact relays are offered to provide alarming in the event of a port link failure or power supply failure. The rugged metal enclosure has an IP30 rating and comes standard with integrated DIN-rail mounting. All devices are UL safety rated and UL approved for use in Class I, Division 2 hazardous locations.

Transition's Industrial media converters and switches are offered in various configurations, with both multimode and singlemode fibre port options. Two operating temperature ranges are available: 0 to +60°C or -40 to +75°C.
