Circuit breaker can be controlled via
the Internet
Siemens Automation and Drives has announced the introduction of a new generation of open circuit breakers which can be controlled and monitored via the Internet.
Siemens Automation and Drives has announced the introduction of a new generation of open circuit breakers The Sentron WL range, which is available both in three and four-pole versions, allows all of the parameterisation, plant operating and monitoring tasks to be handled locally or via Profibus-DP, Ethernet/Internet

Siemens Automation and Drives is extending its family of Opto-BERO 3RG7 proximity switches to include a new optical sensor, which has been specifically designed for the mechanical handling market.
Choosing and Using Soft Starters
Due to the improved operating characteristics they give to the equipment they control, electronic motor soft starters are increasingly widely applied. Peter Costello of Siemens explains
The modular design of its tripping devices and communication components, means Sentron WL can be easily adjusted to varying power distribution concepts.
Sentron WL, which is available in three sizes, from 250 to 6300A, can be connected in different ways and protects against short-circuit currents of up to 150,000A.
A module for calculating rated current, enables quick and easy modification, which means the circuit breaker can be effectively adapted to the plant conditions.

PLC achieves SIL1-3 Safety Standards
The new Simatic S7-400F Fail-safe PLC is the first device of its type in the world to achieve safety integrity across SIL levels 1 to 3 of the IEC 61508 standard, for a single processor.
The electronic overcurrent release, which is at the very heart of Sentron WL, provides a variety of protection, signalling and measuring functions, from simple protection against overloading and short-circuiting to the complex function of remotely setting the parameters.
All intelligent components are linked by Cubiclebus, the internal system bus.
External auxiliary modules can add digital inputs and outputs as well as analogue outputs to expand the circuit breaker.
The Siemens circuit breaker can communicate its current status through Profibus-DP and/or Ethernet, as well as Intranet and Internet.
The control, diagnosis and testing of the Sentron WL, as well as the selecting and adjusting of the parameters are all functions, which can be carried out remotely.
Using the Profibus gateway module, the Sentron WL is connected to the Profibus.
The transfer of data and the setting of the circuit breaker's parameters is enabled through the use of the Switch ES Power software.
If users need to access this data and the parameters of Sentron WL locally, this can now be done due to the Breaker Data Adaptor (BDA), the first ever circuit breaker parameter device with an integrated Webserver.
The data can be accessed and altered through an Internet Browser, without the need for extra software.
The use of an additional Ethernet connection (BDA Plus) enables the user to make the data available on the Intranet or Internet.
An extra module enables damage and warning messages to be sent by text messaging to a mobile phone.
Retrofitting is not a problem with the Sentron WL.
A complete range of accessories, from remote releases through motor drives to communication components is available.
