Remote I/O System Supports Six Different Bus System Protocols

Wieland Electric Inc. has developed a flexible, compact and efficient modular I/O fieldbus system that enables machine design engineers to combine up to 64 user modules on a single bus coupler to send I/O using PROFIBUS, PROFINET, CANopen, Modbus TCP, EtherCAT, or ETHERNET/IP protocols.

“ricosFLEX is one of the fastest, most compact and versatile remote I/O systems available.” said Martin Lalonde, Application Engineer at Wieland Electric. “Its elegant design considers both the system designer and service technicians through a myriad of smart and simple features.”

Modules in the ricosFLEX I/O system include bus couplers for each of the six most common industrial protocols; analog input and output modules with resolutions of up to 16 bits; and digital input and output modules with 2 to 8 channels per module.

Fast reaction times of 20µs are possible with the integrated 48Mbit/s backplane bus. The complete assembly mounts on a standard 35mm DIN rail.

Each ricosFLEX I/O module consists of a base and pluggable electronic function module. The base incorporates space-saving stepped wiring terminals that employ proven spring clamp connections and connections for an integral backplane bus. The electronic function module can be disconnected from the base without tools by means of a secure “slide and click” interlock mechanism. The electronic module can also be removed while allowing the field wiring to remain intact which facilitates maintenance work. LED indicators on the module provide clear diagnostics and channel status at a glance. The wiring diagram of the module is also included on the side of the module eliminating the need to search through manuals and drawings. DIP switches mean fast programming and no need search for software or specialized programming cables. Individual channel assignments can be indicated on the front labeling strips, and the wiring terminal assignments are printed on the module face.

Another benefit of the ricosFLEX system is reduced part count. The bus coupler module includes a power supply and end plate, and the I/O modules are supplied with the mating terminal sockets. Termination resistors are not required. This facilitates stocking and eliminates ordering issues.

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.

TURCK’s BL Compact Family Collects Analog and Digital Signals at the Source

TURCK’s BL Compact system is a revolutionary modular I/O solution for collecting a variety of signals in a single, rugged node on a network. Rather than routing all signals through a control cabinet, this device makes it possible to obtain analog, digital, thermocouple, RTD, serial, RFID or a mixture of signal types in a compact, machine-mountable device over DeviceNet™, CANopen and PROFIBUS ®.

Up to two signals types can be combined in any combination in the BL Compact system, including RFID and analog, digital and serial—and more. The BL Compact system may be customized to suit a user’s specific needs, so that devices may be added to an existing network and signals may be gathered on the machine without an enclosure. This drop-in solution can be used to connect up to 16 devices—drastically reducing the time it takes to run wires for each device back to the control cabinet and the potential for wiring errors.

The BL Compact system is currently available with four, eight or 16 ports i…
