Insert copper wires (sized between 22 and 14 AWG) directly into the push-in terminal points, strictly matching your pre-engineered SIL 3 safety channel schematic.

A deterministic 4.5 ms reaction time guarantees that the moment a safety violation occurs, the module drops power almost instantly, helping you meet strict safety distance standards for hazardous machine parts.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ2: Can I combine copper and aluminum wiring when connecting field devices to the 5094-OB16S?\u003c\/strong\u003e\u003cbr\u003e\nA2: No. The terminal block clamps are rated strictly for 22 to 14 AWG copper wire. Mixing metals can trigger galvanic corrosion and cause loose connections over time, which compromises your safety loop and can lead to nuisance trips.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ3: What does a sourcing safety output do if it detects an external short-circuit to ground?\u003c\/strong\u003e\u003cbr\u003e\nA3: The 5094-OB16S uses smart solid-state switches that detect overcurrent states instantly. If an output wire shorts to ground, the module shuts down that specific channel immediately, signals a diagnostic fault to the main controller, and turns on a front-panel fault LED for easy troubleshooting.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":51047906148484,"sku":"5094-OB16S","price":110.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/7454\/7844\/files\/5094-OB16S.jpg?v=1780062083","url":"https:\/\/www.etowonauto.com\/az\/products\/5094-ob16s-allen-bradley-ple-cat-4-digital-output-module","provider":"Etowon Auto","version":"1.0","type":"link"}
