One source offers all safety system
components
A complete DeviceNet-compatible, SIL 3-rated modular safety system offers reduced installation costs and integration with existing DeviceNet networks.
SICK (UK) has launched a complete DeviceNet-compatible, SIL 3-rated safety solution that as well as being flexible and expandable also offers distributed network IO By offering all of the elements for a safety system, users can also take advantage of full component synergy and a single source of supply for all hardware, services and support

Bridging the optical and photoelectric sensor gap
Erwin Sick's compact DS 60 distance sensors bridge the technological gap between photoelectric switches and optical distance measurement devices.
Photoelectric switches offer huge ranges
The newly developed W140 from Erwin Sick is a complete family of photoelectric switches in miniature housings offering, above all, giant ranges.
With its modular design allowing scaleable system solutions, users will benefit in many different ways, including: reduced installation costs; integration with existing DeviceNet networks, if required; the capability to install decentralised safety logic local to the application; and the opportunity to bridge with other control protocols.
Users also have the flexibility to either combine safety and non-safety protocols on the same network or kept them completely separate.
Another major advantage is that by SICK (UK).

Rehoused photoelectric switches suit more uses
Redesigned photoelectric switches are rehoused in cylindrical M12 housings and offer users a quality, low cost solution suitable for a wide range of applications.
supplying all of the necessary equipment for a complete safety infrastructure, users can reap the benefits of using a single supplier, such as better component integration, a single source for spares and upgrades and the support of a single dedicated safety expert.
With its diverse and in-depth knowledge of safety technology and protocols, SICK (UK).
can partner with companies to develop safety concepts that will satisfy applications as diverse as single-purpose, standalone machines through cell automation up to line and plant automation.
Primary applications envisaged by the company include packaging machinery, manufacturing production lines, logistics operations, robot cells, machine tools and transfer lines.
Based on a compact safety controller equipped with onboard safety I/O, SICK's UE4400 safety network controller devices integrate and evaluate any combination of safety input and actuator devices into DeviceNet Safety networks, using local or remote safety capable inputs and outputs.
Primary features include central diagnosis capability of the complete application, remote IP67 and IP20 IO and connectivity with S3000, C and M4000.
In addition, by using a compact safety controller that 'enables' DeviceNet safety, there is not need for a PLC.
System configuration is done using a graphical configuration tool and pre-certified function blocs and 'plug-ins' are available to allow integration into existing third-party network configuration tools, while status, diagnostic and error information can be easily accessed locally or through the network.
DeviceNet Safety provides the simplest means possible of implementing a safety network and integrating it into a wider enterprise network topology.
The safety extension allows safety devices to coexist with standard control devices on the same network: safety sensors can operate alongside variable speed drives and safety controllers with standard PLCs and proximity switches.
No matter what combination of devices is used, the integrity of the safety control loop cannot be affected by any of the standard control devices.
One of the key strengths of the DeviceNet Safety solution is that, unlike other safety networks, it has the ability to connect safety devices and standard devices on the same network or wire, either with or without the need for a Safety PLC.
