The multiple light beam safety devices of the MLD series are now also available with an integrated AS-i Safety interface.

The MLD/AS-i safety sensors can now be integrated immediately into the AS-Interface network, i.e., without additional coupler modules and hence cost-effectively.

Especially when it comes to muting, the direct AS-i connection allows very convenient solutions for users who place an emphasis on economy. In cooperation with the Leuze electronic Safety Monitor ASM-m, the MLD multiple light beam safety devices permit the easy construction of access guarding with muting based on AS-i Safety at Work.

The ASM-m Safety Monitor takes care of controlling the muting process, including driving the muting indicator integrated into the MLD via AS interface. Unlike before, it is no longer necessary to assign an AS-i slave address specifically for the muting indicator. This also applies to an external muting indicator connected to the local socket of the safety sensor.

This saving allows even more AS-i slaves such as safety sensors to be connected to an AS-i network for each AS-i Safety Monitor.
