Safe input/output modules

Safe AS-i modules detect safety-related switching states of 1- or 2-channel E-stops, position switches or door contacts. Using the safe input module safety-related components without integrated AS-i interface can be connected to the AS-i system.
The units comply with the applicable international standard requirements for safety technology. They detect and signal short circuits, cross faults and communication errors. The switching states of the inputs and outputs, the voltage supply and potential faults are indicated by powerful LEDs on the module.
The product range includes ClassicLine modules with screw or quick mounting technology for field use and SmartLine modules for control cabinet installation.
