IntroductionThe ClassicLine Safety at Work module connects fail-safe inductive sensors to AS-interface. Evaluation to theSafety at Work protocol is carried out with one of thefour available AS-i safety monitors.The safe data transmission on the AS-i bus has alreadybeen approved by TÜV and BIA and is suitable for thetransfer of signals up to the highest category 4 toEN 954-1.Powerful LEDs on the front panel indicate switchingstates of the inputs and outputs, voltage supply andfaults at the module, if any.The safe AS-interface input module AC016S is approvedfor up to category 4 to EN 954-1.

The new input module AC016S allows the connectionof fail-safe inductive sensors of ifm electronic up to cat-egory 4 to EN 954-1. This input module enables the con-nection of up to 8 safety-related inductive sensorswithout integrated AS-i interface to the AS-interfacesystem.In addition to the safe input these units also feature aswitching output for actuators which allows magneticguard locking controlled by AS-i.
Advantages and customer benefits
• Diagnosis and self-testThe safe ClassicLine slave carries out a periodic inter-nal self-test after power on. It is transferred as thesafe state to the master (triggered = code sequence“0000”). After power on and successful function testthe Safety at Work protocol is started (not triggered =cyclical transmission of the code table). The safe inputis now ready for operation.During operation the redundantly designed module ispermanently monitored. The input is monitored forcross faults. In case of a fault a red fault LED indicatesthe fault. In addition an AS-i peripheral fault is gener-ated.
• The Safety at Work systemIn principle, the AS-i safety technology consists of twocomponents: Of one safe input slave for connection ofthe safety devices and the safety monitor as a moni-toring element with positively-driven relays for thesafe switch-off of the drives or actuators. The otherAS-i standard components, like master and currentsupply, remain unchanged.
• AddressingAddressing is done before mounting via the adapterintegrated into the addressing unit or after mountingby means of a module lower part with addressingsocket and an addressing cable with a jack plug.Using the ifm controller e addressing is even moreconvenient. The large graphic display gives the user anoptimum overview.
ApplicationThe fail-safe AS-i ClassicLine module can be used in awide range of different applications. It is suitable wheredecentralised I /O, modular design and simplicity of thesystem are important and a high protection ratingagainst environmental influence is required.
