Intended Use
The device can be used as a safety module with safety-related inputs for connecting mechani-
cal contacts, such as emergency-stop switches, and an optional conventional electronic out-
put, e.g., to activate signal lights. When used in this way in conjunction with a programmed AS-
Interface safety monitor, the device allows operation of sensor-controlled personal protective
equipment up to category 4/PL e as per ISO 13849-1, or up to SIL 3 as per EN/IEC 62061.
The maximum service life of the AS-Interface safety module is 20 years. Replace the device as
a matter of course after 20 years at the latest.
Safety Classification
The module contains two independent, redundant input channels. If both input channels are
used, the module is suitable for use up to category 4/PL e in accordance with ISO 13849-1, or
SIL 3 in accordance with EN/IEC 61508 and EN/IEC 62061. In this case, the monitor must be
programmed so that dual-channel switching is monitored.
If a single-channel switch is used, the module is suitable for use up to category 2/PL c in accor-
dance with ISO 13849-1, or SIL 1 in accordance with EN/IEC 61508 and EN/IEC 62061. Only
tested and certified power supplies with safe isolation may be used to supply power. These
power supplies must have PELV voltage in accordance with EN 50295/IEC 62026-2, and a
minimum MTBF of 50 years. The power supplies are designed to exclude a short circuit
between the primary and secondary sides.
