ASi Modules with integrated IO-Link Masters

With the ASi modules with integrated IO-Link masters from Bihl+Wiedemann intelligent IO-Link sensors and actuators can now be easily incorporated into ASi – exactly there, where they are needed. The IO-Link sensors can be easily parametrized using the configuration tool from Bihl+Wiedemann.

In many application scenarios, IO-Link solutions from Bihl+Wiedemann are much more cost-efficient than similar solutions from other providers. An application with Bihl+Wiedemann is already cheaper than comparable PROFINET variants from three 4-port IO-Link masters. Another factor is the finer granularity. Our 1-port IO-Link master allows you to integrate an IO-Link device exactly where you need it. Thanks to cable-piercing technology, it is extremely easy to install our IO-Link master. You can substantially reduce the time required for assembly.

Under normal conditions (no bus termination or repeater), the permissible total length of the ASi segment is max. 100 m. The calculation should take into consideration that the length of the connection cable (round cable) for each connected passive distributor must be doubled.

In the case of the active distributors (ASi modules) however only the one ASi profile cable is counted.
