Ethernet Products for Machine Building

Westermo has launched the i-line Family of Ethernet products optimised for machine building, building automation, factory automation and CCTV surveillance applications. The new range includes standard and mecompact Ethernet switches, media converters and Power over Ethernet (PoE) switches. The Westermo i-line offers industry grade components, easy-to-use features, and reliable and consistent operation. All i-line devices are DIN rail mountable and have dual 24VDC power screw terminal inputs making them suitable for applications where a secondary power source is used to maintain high system integrity. Each device in the range incorporates a configurable relay that triggers an alarm signal for port or power events. The rugged IP-31 rated aluminium alloy enclosure is ideal for heat dissipation and enables a wide operating temperature range. Among the products being introduced is a standard eight port 10/100TX Fast Ethernet switch (SDI-880). This is equipped with a 2 Gbit/s packet switch engine that supports two priority queues so as to provide optimum data forwarding performance. A second eight port Ethernet fibre switch (SDI-862) has six 10/100TX ports and a choice of either two multimode or single mode fibre ports, enabling data to be transmitted for distances up to 2 km or 30 km respectively. Two compact (111.8 x 30 x 98.2 mm) five port switches are also available. The SDI-550 is a simple 5-port 10/100Base-TX Ethernet switch, whilst the SDI-541 is a five port industrial fast Ethernet switch with four 10/100Base-TX ports and a 100Base-FX port supporting both single and multimode fibre. Both models can operate with variable power sources including a 24 V AC supply, making them ideal for the building automation industry.
