The collection and transmission of various signals to the controller level used to require the use of a cable bundle as thick as your arm. Starting now the sensor hubs from Balluff offer a variety of typical IO-Link benefits especially for non-IO-Link capable sensors. The newly devel-oped collectors for simple binary switching signals permit bundling of 8 or 16 inputs to a single IO-Link input port. Instead of a multi-conductor cable, transmission is typical IO-Link with a simple 3-conductor standard cable.
The installation effort and expense are greatly reduced compared with conventional approaches. Tedious stripping of up to 20 individual leads is eliminated, mistakes from crossed connections and the resulting trou-bleshooting are all a thing of the past. One hub model offers 8 ports which are dual-use (Pins 2 and 4) and permit optional connection of 16 standard, 8 push-pull or DESINA sensors. Another variant offers 4 analog ports as well as 4 dual-use ports. The next logical development step has already been taken, since 4 of the 8 ports may also be analog. The unique feature: This sensor hub can be parameterized via IO-Link so that either the digitized analog value is sent to the controller or a configurable switching point evaluation is already done in the sensor hub.
