It provides eight solid-state sourcing outputs, each rated at 1 A, with a total aggregate current capacity of 8 A per module. The module supports dual-channel mode for redundancy, enhancing functional safety performance. It operates with a nominal supply voltage of 24 VDC within a range of 19.2–28.8 VDC and has a maximum power dissipation of 4.5 W. Safety features include short-circuit detection, cross-circuit and overload protection, and diagnostic indicators for channel, power, and lock status. The unit has an isolation rating of 50 V continuous between field and system sides, tested to 707 VDC for 60 seconds. Compact and DIN rail–mounted, the 1734-OB8S is widely used in safety control architectures for manufacturing, material handling, and machine automation systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOutput Channels: Eight solid-state, current sourcing outputs rated at 1 A per channel, 8 A aggregate.\u003c\/li\u003e\n\u003cli\u003eVoltage Range: Operates at 24 VDC nominal, with 19.2–28.8 VDC supply range.\u003c\/li\u003e\n\u003cli\u003eSafety Functionality: Supports dual-channel mode for redundancy and reliable safety integration.\u003c\/li\u003e\n\u003cli\u003eProtection: Built-in detection for short circuits, cross-circuit faults, and overload conditions.\u003c\/li\u003e\n\u003cli\u003ePerformance: Reaction time up to 6.2 ms with maximum field capacitance per output of 950 nF.\u003c\/li\u003e\n\u003cli\u003ePower: Maximum power dissipation of 4.5 W, typical 3.02 W, with thermal dissipation of 15.38 BTU\/hr.\u003c\/li\u003e\n\u003cli\u003eIsolation: 50 V continuous insulation between field side and system; tested at 707 VDC.\u003c\/li\u003e\n\u003cli\u003eDiagnostics: Includes status LEDs for module lock, power, and individual channel activity.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 1734-OB8S delivers the reliability and precision required for safety-critical output control in industrial automation.\u003cspan style=\"font-weight: 400;\"\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":47143133937962,"sku":"1734-OB8S","price":141.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/1734-OB8S_b4bdaedc-c63a-42eb-b8ed-577dc7334ca0.jpg?v=1722246938","url":"https:\/\/iqelectro.com\/products\/allen-bradley-1734-ob8s-point-i-o-8-channel-safety-sourcing-output-module","provider":"IQElectro","version":"1.0","type":"link"}
