| Serye | SAFE-SIL |
SAFE-SIL ay isang universal na safety coupling device na may tatlong safety relay contacts para sa mga safety switch, na sertipikado ng T Ü V Rheinland. Ang SAFE-SIL ay maaaring i-couple ang lalabas na safety signal mula sa pulse PIC patungo sa field para sa current isolation at power adjustment, o ito ay maaaring gamitin bilang contact extension para sa basic equipment. Walang feedback circuit ang kinakailangan. Ang disenyo nito ay sumasang-ayon sa EN ISO 13849-1, EN 62061, at EN 61508.
