With the two input modules BWU4209 for floating contacts and BWU4210 for optoelectronic protective devices Bihl+Wiedemann presents the first products with ASi-5 Safety technology. The safety version of ASi-5, which has already been certified by TUEV, is always the ideal supplement for ASi Safety at Work when several safe signals or a combination of safe and non-safe signals are to be transmitted.
Like ASi-3 and ASi-5 in the non-safe area, the two safety versions of AS-Interface also work completely in parallel on the same profile cable. Both ASi-5 Safety modules in protection category IP67 have two safe two-channel inputs and 12 self-configuring I/Os for non-safe signals. If an output bit is set in the PLC output data, it is an output with switching diagnostics in the corresponding input bit. If not, it is automatically mapped as an input signal in the PLC input data. In this way, these modules, which can be realized at almost the same price as comparable purely non-safe I/O modules, can be used to implement very different applications, depending on requirements, such as an extremely cost-effective connection of a control panel with several light buttons, an E-stop button and a safe key switch to ASi. The two modules are connected via ASi profile cable. The inputs and outputs are supplied out of AUX, the connection to the periphery is realized via eight M12 sockets, each with five pins.
By the end of 2022, the product range will be gradually expanded so that one module each will be available for two floating contacts, two optoelectronic protective devices and for the combination floating contact/OSSD in the following versions: as an IP67 field module with an additional four standard in- and outputs and as an IP20 control cabinet module, IP67 field module and PCB module with an additional 12 standard in- and outputs each.
