The safety relay meets the requirements of EN 60947-5-1, EN 60204-1 and VDE 0113-1 and may be used in applications with
Light beam devices
The relay meets the following safety requirements:
The circuit is redundant with built-in self-monitoring.
The safety function remains effective in the case of a component failure.
The correct opening and closing of the safety function relays is tested automatically in each on-off cycle.
The unit has an electronic fuse.
