Making safety interlocks bus capable

Bihl+Wiedemann now offers AS-i Safety active distributors with integrated AS-i chip especially for Schmersal and Pilz interlocks. They are used to easily incorporate safety interlocks from these manufacturers into AS-i systems: The connection between the interlock and our module is done with 8-conductor M12 cables integrated into the active distributor. The cable length between the distributor and interlock thus has no effect on the allowable total length of the AS-i network.

Position safety interlocks as desired

Their especially compact form factor is ideal for cable ducts, allowing you freedom in cable routing paths. And thanks to pre-assembled cables you save hardware costs and wiring time while at the same time minimizing possible wiring mistakes.

 

Versions for interlocks from other manufacturers are available on request.
