In addition to the Safe Output for 20 A (BW3016) Bihl+Wiedemann now offers a cost-effective 10 A version as well. The Safe Electronic Output 10 A (BW3281) enables wear-free, safe switching of 24 V.
Contactors and safety relays are only good for a limited number of switching cycles. The safe electronic outputs for 24 V on the other hand are practically wear-free.
