Signal isolator - high availability and functional safety

The requirements on operational and safety-related circuits in plants are continuously growing which also affects the technical requirements on components. Often, functional safety can only be increased with much effort and at the expense of availability. Proving that high safety stand- ards and high availability can go hand in hand, Knick present ProLine P 22400 passive standard signal isolators certified for applications with a SIL3 safety integrity level according to EN 61508.The passive isolator’s

Schneider Electric’s chief executive officer champions gender equality

Since 2013, each WEPs Annual Event has included the an- nouncement of theWEPs CEO Leadership Awards, saluting five exceptional chief executive officers for championing gender equality and the 7 WEPs Principles, in particular Principle One, which urges these leaders to lead by example. Jean-Pascal Tricoire, chairman and chief executive officer at Schneider Electric, was awarded one of the five Awards for his demon- strated commitment to and implementation of policies that advance and empower women in the workplace, marketplace and community. The 2015 Business Case for Action Award recognised Schneider Electric ’s for its Diversity and Inclusion policy, which prioritises communicating the business case for diversity and creating a company-wide gender balance environ- ment that extends beyond the parent company tomore than 10 Schneider Electric chief executive officers of its international branches in countries from Vietnam to Turkey.

In selecting the appropriate CCTV solution, we recommend four important steps: define the areas that need to be monitored and specify the expected results of the system.

safety functionality is the highly precise, linear transmission of 4...20 mA signals with a low transmission error of 0,08 % full scale. A high level of functional safety can be achieved even in single-channel struc- ture and without diag- nostics. For instance,

sensors and actuators in safety circuits can be connected directly, requiring no elaborate evaluation equipment for redundant structures. The isolator’s robust design ensures excellent availability with a mean time between failures of 965 years.Thanks to loop-powered operation, it contains fewer parts than devices with an auxiliary power unit and the total failure rate is decreased. Furthermore, it is mechanically stable, approved for marine appli- cations, resistant against electromagnetic interferences, and boasts protection against electric shocks up to 600 V ac/dc through reinforced insulation. The test voltage during routine testing is 5,4 kV ac. ProLine P 22400 is suitable for ambient temperatures between -40 and 85 °C. Knick provide a five-year warranty for all ProLine devices. Mecosa is the sole agent for Knick ElektronischeMessgeräte in Southern Africa.

Data showed the cost of those accidents that did occur were 27 % less as a result of instant intervention. Intelligent Telematics operations director, Craig Lovell, says they are seeing mul- tiple benefits from using a 3G vehicle camera, which are helping fleets to operate more responsibly while at the same time reduce overheads. "The 3G cameras are not only preventing incidents and discourag- ing other road users from making fraudulent or inflated claims, but when an accident does happen the footage is available from the scene within seconds so first notification of loss is helping achieve substantial insurance claim cost savings,” he explains.The analysis also found that 65 % of the accidents recorded were in fact avoidable, highlighting a clear opportunity to improve fleet safety levels through improved and targeted driver engagement.With this in mind, companies are increasingly using the information provided by the vehicle cameras to pro-actively improve driver behaviour.
