3.2 Structure and function
The safety relay ReLy OSSD1 is an electrical switching device with inputs and outputs.
T
he safety capable inputs of the safety relay are connected to safety sensors.
2 safety capable inputs control the internal relays, which are used to reliably switch the
enabling current paths.
At the enabling current paths it is possible to connect, for example, actuators with
positively guided contacts.
