Decentralised IO-Link input module for field applications - for the first time also for hygienic areas
Decentralised collection of digital signals via IO-Link
The new IO-Link input modules for field applications allow easy and economical adding of up to 20 digital inputs to IO-Link masters. The activation of digital input filters such as debouncing, stretching or inverting allows easy optimisation of the input signals.
The module is available in two designs: The orange field module from the coolant series is resistant to oils and coolants and suited for general industrial applications. The grey module is ideally suited for hygienic and food applications due to the material used for the housing. It has the high protection rating IP 68 / IP 69K.
Field modules with IO-Link connection
Up to 20 conventional sensors can be connected to these modules. IO-Link transfers the signals to any IO-Link master / PLC via one unscreened M12 cable. A special feature of the modules is the pre-processing of the input signals via different filters before passing them on to IO-Link. The following filters are available: debouncing (suppress noise signals), stretching (longer signals), inverting. This allows reliable detection of signals with a minimum length of 1.5 ms. The decentralised positioning of the module reduces wiring costs and makes complex cabling obsolete. As opposed to bus systems IO-Link does not require any configuration or addressing. This simplifies installation. Pins 2 and 4 of each M12 socket are configured as binary inputs. That means that dual sensors, normally closed or normally open, can be connected without any problem. The inputs have full overload and short-circuit protection.
