AC0075 module for safety devices
February 2010
Sensors & Transducers
ifm electronic’s AC007S module is designed to connect safety devices such as fail-safe sensors and light curtains to the safety version of ActuatorSensor-Interface(AS-i). Ideal for use with ifm electronic’s safe proximity sensors, the SIL3-compliant AC007S module takes an OSSD (output signal switching device) input from a sensor or other ESPE (electrosensitive protective device). It then checks the integrity of that signal for cross faults, for example, as well as the switching status of the ESPE and its own internal integrity and transmits this data via As-i Safety at Work.
Overall safety is ensured on the AS-I Safety at Work system by the safety monitor, and the data transmission on the AS-i bus has been approved by TUV and BIA. It is suitable for signal transmission up to the highest category 4 to EN 954-1 and IEC 61508/SIL3.
The IP67-rated AC007S safe input module can be field-mounted along with other standard or safe devices on the AS-i cable, which supplies power for the unit in addition to bus signals. The AC007S features bright LEDs for visualisation of signal states or possible faults, while connection to the input can be via industry standard M12 connectors or cage clamp terminals.
