Integrating Individual IO-Link Devices Cost-Effectively

IO-Link devices are widely distributed in many systems. However, the maximum cable length between an IO-Link master and an IO-Link device is 20 meters. The solution of the problem: Bihl+Wiedemann ASi-5 / IO-Link master with 1 or 2 ports.


Easy Installation & Totally Unrestricted Topology

With our IO-Link masters, you can connect individual IO-Link devices at any location easily and cost-effectively – distributed over the ASi cable length of up to 200 meters. Your advantage: You integrate just as many ports as you really need at the individual points of the machine. You can connect any IO-Link device – without any restrictions of the topology.


Modules of other manufacturers usually have at least 4 IO-Link ports. This makes every individual connection considerably more expensive. Because if there are only 2 IO-Link devices within a radius of 20 meters, you would still have to pay for the 4 IO-Link ports of the "small" IO-Link master. With Bihl+Wiedemann you can get rid of that overhead and reduce your costs. You can also use our IO-Link masters to connect IO-Link devices to different fieldbuses – for example: PROFINET, EtherCAT or EtherNet/IP.

40 % Cost Savings for Mid-Sized Applications

Bihl+Wiedemann also offers IO-Link masters with 4 ports. These are significantly cheaper than comparable Ethernet variants. With ten IO-Link devices, you can save an average of eight percent, and with 50 devices the saving can be as much as 40 percent. The piercing technology makes them extremely easy to install and you also save a lot of assembly time.
