Product description
3.1
Construction and function
The safety relay ReLy TIME1 is an electrical switching device with inputs and outputs.
The safety capable inputs of the safety relay are connected to safety sensors or safety
switches.
2 safety capable inputs control the internal relays, which are used to reliably switch the
enabling current paths.
The enabling current paths close only when the two safety capable inputs close within
3 s of one another.
Actuators with positively guided contacts are connected to the enabling current paths.
Opening the input circuit causes the two enabling current paths to open immediately
and for the release-delayed enabling current path to open after a delay. The delay time
is adjustable.
