    The safety functions must be defined first. This information is derived from the risk assess- ment. Example: Trigger event: Opening the safety door. Response: The robot drive is set to a safe stop state. The power semicon- ductor pulses are disabled. Safe state: Power circuit has no power. 10 / 136 PHOENIX CONTACT 102597_en_03...

    In the next step, a safety-related block diagram must be created for further evaluation. As a rule, a safety function consists of sensor - logic - actuator. In the simplest case, each one is a subsystem. These subsystems are connected in series to form the overall safety function. 11 / 136 102597_en_03 PHOENIX CONTACT...

  • Page 26: Safe Isolation

    Due to the internal structure and the insulation properties between the input and the contacts in Phoenix Contact PSR safety relays, 250 V AC, for example, can be switched without any limitations. The output contacts (13-14, 23-24, …) are isolated using basic insulation or rein- forced insulation, depending on the type.
