Optoelectronic safety device

Optoelectronic safety device having

• a light transmitter (14) for emitting transmitted light beams (16) into a monitored area (22),
• a light receiver (30) for generating reception signals from received reception light beams (26) which originate from reflections of the transmitted light beams (16) on at least one object (24) in the monitored area (22),
• an evaluation unit (32) for evaluating the received signals and for outputting a safety signal depending on the received signals,
• wherein the evaluation unit (32) has a computing unit (42) with at least two CPUs (44, 46), wherein the computing unit (42) is not a dedicated safety module and is designed as a standard multi-core processor based on only one single semiconductor substrate and the evaluation of the signals takes place redundantly on both CPUs (44 and 46) of the computing unit (42),
• and the evaluation unit (32) has a watchdog controller (50) which monitors the function of the computing unit (42), wherein the watchdog controller (50) can cause the evaluation unit (42) to output the safety signal independently of the computing unit (32).
