The new Profibus extender from Phoenix Contact enables straightforward integration of remote Profibus devices at data rates of up to 1.5 Mbps. The extender has two DSL connections per device. This means that in addition to point-to-point connections the extender can also be used to easily establish line structures with up to 30 devices.
The Lightning Monitoring System LM-S from Phoenix Contact provides information online about lightning strikes in plants and systems. As a consequence, service call planning can be optimized. This new system identifies and analyzes all of the important parameters of lightning surge currents based on the Faraday effect.
The demand for mobile Internet services is forever on the rise. Thanks to WLAN, it is possible to surf in the global network in nearly all buildings and major metropolitan areas. However, network coverage can be spotty outdoors, in public spaces, and especially in rural areas.
I would like to share my experience which I encountered during my recent safety training to a customer in Malaysia. The topic was on Safety in Machine which the core topic was on the New Standard EN ISO 13849-1 which will be the successor to EN 954-1 ( EN954-1 will be invalid from 28-Dec-2011 )
I realized that 80% of the time I was explaining on the newly introduce Performance Level (PL) and Safety Integrity Level (SIL). During the discussion, there was a question from an engineer.
“In this case, in future we will all use the highest Safety Integrity Level (SIL) say SIL3 or SIL4 and our system will be good and safe”
The protection concept for IT equipment must be able to handle both partial lightning currents and surge voltages, and requires customization appropriate to the data transmission system used.
SURGETRAB surge voltage protection devices are for all commonly used standard signals that are installed directly to the field equipment. This type of installation saves time and money, and an additional connection box for accommodating surge voltage protection is no longer necessary.
LINETRAB sets a new standard in the 6.2 mm class as the narrowest surge protection device for MCR technology. Now up to four signal paths can be protected at the same time. A comprehensive product range comprises suitable protective circuits for all binary, analog and intrinsically safe circuits.
Poor grounding and surge protection practices often destroy electrical and electronics systems to a large extend and can result in continual and intermittent difficult-to-diagnose problems in a facility.
