  • Page 29: Applications

    Applications Commonly used applications are listed in the following chapter. All of these functions can be performed using the 3TK2845 multifunction device. The advan- tage of using this device is the fact that several safety-related functions i.e. pro- tective door monitoring and monitoring using non-contact protective equipment (BWS) such as light curtains and safety mats can be implemented using only one 3TK2845 multifunction device, rather than using several safety combina- tions.
