Safe relay outputs can now be used anywhere in the field!

Our new Safety Relay in IP67 is available. For the first time ever, with BWU4379 you can now take advantage of safe relay outputs in any location within the field, exactly where you need them. The Safety Relay is equipped with an additional safe input, a standard input, and the ability to safely switch-off AUX via a relay path. This provides a broad range of software applications to choose from.

The New 8-Port IO-Link Master Pushes Boundaries

The latest 8-Port IO-Link master (BWU4386) now allows several hundred IO-Link devices to be integrated into a single ASi circuit. The ASi-5 module also offers a high degree of flexibility. This is because 1 to 32 bytes of process data and 1 byte of PQI diagnostics can be freely configured for each of the 8 IO-Link Class A Ports. The 16 digital inputs/outputs also enable each M12 socket to be used either for IO-Link or for binary sensors and actuators.

Control (digital) RGB/RGBW LED Stripes with ASi-5 easy and cost effective

With our new active distributors ASi-5 BWU4083 and BWU4101 you can easily control almost all common (digital) LED Stripes - thanks to the separate profiles for RGB and RGBW as well as the intuitive configuration via the cyclic data. Another advantage: The modules allow a flexible connection of the LED Stripes, the supply of the LED Stripes is done out of AUX.

New 24 V Brake Chopper Manages the Feedback of Generative Energy

Our product portfolio for Material Handling and Drive Control is growing: the new 24 V brake chopper BWU4915 is now available. The extremely flat brake chopper limits the overvoltage that occurs during braking when operating 24 V roller drives. This prevents unwanted mains disconnections or error messages due to overload.

Free yourself from current delivery shortages. Use our new I/O product family for this purpose – and obtain all the devices you need in sufficient quantities even in the future. When developing the new modules, we have paid particular attention to two things: Firstly, that we only use components that are available in large quantities even in extremely difficult procurement markets. Secondly, the focus in designing the modules was to develop a high-performance and cost-efficient technology.

Control DGM/DGM-R drives comfortable and save costs

With our ASi-5 PCB modules, it is possible to add an ASi-5 interface to a wide range of applications. The control elements shown in the figure below are a typical example of this. By means of the compact PCB modules (W / H / D: 70 x 40 x 26.5 mm), they can be easily integrated into the control system via ASi – decentralized and in an existing housing.
