SAFE-TWO-HAND safety relay ay isang napakompaktong panguniversidad na dual hand control device. Ito ay sumasang-ayon sa EN ISO 13851, type IIIC, at itinutukoy para sa paggamit sa mga safety circuit na disenyo batay sa EN 60204-1, tulad ng sa stamping machines, punch presses, at bending equipment. Dahil sa internal error monitoring nito, ang dual hand safety relays ay maaaring gamitin para sa mga aplikasyon na sumusunod sa safety level 4 ng EN ISO 13849-1, SILCL 3 ng EN 62061, o type III C ng EN ISO 13851.
