Compact, Stand-Alone Safety Controller

The VAS-2A8L-KE4-8SE is an innovative programmable safety controller that's cost-effective, adaptable, and easy to install, configure, and run.  This safety controller is a compact and flexible stand-alone solution that delivers the performance and price point that is right for even the smallest systems, with an expansion port that enables it to grow with the application.  The safety controller provides four redundant safe inputs and two independent safe electronic outputs.  It runs on standard 24 VDC and allows any safe device with dry contacts or electronic safe outputs to be used.

“The market is flooded with safety relays and configurable safety controllers that can get the job done. Most of the higher-end solutions are too complex and costly for all but the largest and most difficult applications while low-end controllers lack the necessary flexibility to adapt when application requirements change, even just a little,” says Helge Hornis, PhD, Manager Intelligent Systems Group.

“And no matter how well a system is planned out, things happen and needs change.  This is why the new Pepperl+Fuchs approach is so ingenious.  Not only is it ideal for safety applications using a small number of safe inputs, but its flexibility makes it easy to add safe inputs and outputs by simply connecting enclosure or field mounted safety expansion modules or intelligent safety devices to the unit’s expansion port,” continues Hornis.

Connecting safety devices to this safety controller is as simple as wiring a conventional safety relay.  Removable terminals simplify installation and field service.  An intuitive drag-and-drop application interface makes it easy to configure even complex safety operations in just minutes.  When the configuration is downloaded into the safety controller, documentation is automatically created, and all necessary data is backed up on a memory card.  This makes it fast, easy, and error-free to add or replace a safety controller.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…


TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

IDEC Releases New Line of High Efficiency Power Supplies

IDEC Corporation announces the PS5R-V line of DIN-rail power supplies, offering their customers high-efficiency in a compact form factor at competitive prices. These power supplies suit a wide range of needs in the industrial marketplace, and carry all of the required certifications necessary for use in these demanding applications. This next generation of the industry standard PS5R power supply family has updated features and specifications to meet current and future needs.

The PS5R-V line of power supplies includes 10W, 15W, 30W, 60W and 120W versions, with additional versions coming soon. These power supplies have a very compact form factor with overall dimensions reduced by up to 25% from previous generations. The reduced form factors combine with DIN-rail mounting to free up valuable control panel space and reduce installation costs.

Operating temperature ranges up to -25 to +75 degrees C offer more versatility. These extended operating temperature ranges often allow these power…
