SAFETY SWITCHING ARRANGEMENT FOR OUTPUTTING A SWITCHING SIGNAL

Method for producing data telegrams having CRC fields offering a reduced residual error probability

Safety switching device, has control unit designed to activate outputs during request of corresponding signals, where signals are combined and separated in line and evaluated from each other at device

Method for recognizing security input extension within modular security system in industrial automation field for e.g. controlling consumer, involves outputting signal by base module over output when another signal is received at two inputs

Erweiterungsmodul für ein Sicherheitssystem

Modular safety system used in industrial automation technology field, has processing unit which is checked to determine whether static signal is received properly at first input and dynamic signal is received properly at second input

EXPANSION MODULE FOR A SECURITY SYSTEM

Transfer of security oriented entry signals through a non-secure channel by means of a security oriented telegram

Circuit arrangement and method for an electronic system for time-delayed outputting of a switching signal

Circuit arrangement and method for an electronic system intended to timed transmission of a switching signal
