Frequently asked questions

What is the function of the integrated snubber circuit in the 6ES7322-1HF20-0AA0?

The integrated snubber circuit (RC damping network) in the 6ES7322-1HF20-0AA0 module helps to reduce arcing across the relay contacts when switching inductive loads. This protection extends the lifespan of the contacts and ensures more reliable operation.
