Hi,
I would like to confirm my understanding of Safety category 2 and 3. I'm new to this and just researched on the internet. We are designing a Emergency Shutdown system on a Biogas Plant.
Safety category is based on the wiring strategy and not solely based on the safety rating of the devices (i.e. e-stop, safety relays, etc.). My understanding is category 2 has a single input and output. Category 3 has a redundant input and output.
Is my understanding correct?
Also, are there any standard regarding safety category based on the application? As stated, we are designing the ESD on a Biogas Plant.
Thanks.
