When the safety input is deactivated (e.g., an emergency stop button is pressed), the relay will not immediately de-energise. Instead, it will wait for a preset time before switching off. This delay can be useful to ensure that machinery or processes have enough time to come to a safe stop before the relay de-energises.
In practical terms, the delay-on de-energisation can be adjusted based on your specific needs, allowing for flexibility in safety and timing requirements. http://www.pilz.com Make sure to refer to the PNOZ s5 user manual for detailed instructions on how to configure the delay settings properly.
