Flexible, Safe I/O Distribution without a Safety Controller

Phoenix Contact’s new SafetyBridge technology makes it possible to distribute safe I/O modules in a network without the need for a safety controller.

SafetyBridge technology allows the input and output modules to exchange safety-related signals with one another. Since the modules process the safety function themselves, the standard control system and network are only used as a transport medium.  By eliminating the safety controller and safe fieldbus system, SafetyBridge technology can reduce the cost of a safety system.

The safety logic operations are directly processed in the intelligent safety output module. The safety modules can be distributed throughout an automation system using Phoenix Contact’s Inline Modular I/O.  SafetyBridge easily integrates into PROFIBUS, PROFINET, INTERBUS, and EtherNet/IP protocols over Phoenix Contact, Siemens Step 7 and Allen-Bradley RSLogix 5000 control suites.

The Safeconf software makes it easy to parameterize the safety input and output channels and generate the safety logic, even for those without programming experience. Pre-configured function blocks are available for almost any application.

The standard control only has to copy non-safety I/O data bidirectionally between the input and output modules. Consequently, the control does not handle any safety-oriented tasks.

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

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.

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…

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…
