Optimized for demanding industrial environments, this module provides eight sourcing output channels configured in two isolated groups of four. It is specifically built to handle high-current loads, making it an ideal choice for driving heavy-duty actuators, large solenoids, and high-wattage indicators that require more power than standard I\/O modules can provide.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Current Capacity:\u003c\/strong\u003e Delivers a continuous 2.0 Amps per point across the full operating temperature range (0 to 60 degC) without thermal derating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated Diagnostics:\u003c\/strong\u003e Includes e-fuse LED status indicators for each channel, enabling rapid visual fault detection and maintenance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIsolated Architecture:\u003c\/strong\u003e Outputs are organized into two distinct isolated groups to enhance circuit protection and system flexibility.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRobust Power Handling:\u003c\/strong\u003e Capable of managing a total module current of 8.0 Amps, with a surge current capacity of 4.0 Amps per point for 10 ms.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eSLC 500\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eHigh-Current DC Sourcing Output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Outputs\u003c\/td\u003e\n\u003ctd\u003e8 (2 groups of 4)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e20.4 to 26.4V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current (5V)\u003c\/td\u003e\n\u003ctd\u003e0.135 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOn-Signal Delay\u003c\/td\u003e\n\u003ctd\u003e1.0 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOff-Signal Delay\u003c\/td\u003e\n\u003ctd\u003e2.0 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax On-State Voltage Drop\u003c\/td\u003e\n\u003ctd\u003e1.0V at 2.0 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Off-State Leakage\u003c\/td\u003e\n\u003ctd\u003e1.0 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin Load Current\u003c\/td\u003e\n\u003ctd\u003e1.0 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Safety:\u003c\/strong\u003e Always disconnect backplane power before inserting or removing the module from the chassis to prevent electrical damage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Ensure the module is fully seated in the SLC 500 chassis slot and secured with the integrated locking tab.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring:\u003c\/strong\u003e Utilize shielded cabling for output signals to minimize EMI interference, especially when driving inductive loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnvironment:\u003c\/strong\u003e Maintain adequate clearance around the chassis to ensure proper ventilation and cooling, adhering to the 0 to 60 degC operating range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrounding:\u003c\/strong\u003e Follow standard industrial grounding practices for the chassis and power supply to ensure signal integrity and safety.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the 'P' in 1746-OBP8 stand for?\u003c\/strong\u003e The 'P' designates this module as a high-power output variant, specifically engineered to drive larger electrical loads compared to standard SLC 500 output modules.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this module require thermal derating?\u003c\/strong\u003e No, the 1746-OBP8 is rated for a continuous 2.0 Amps per point across its entire specified operating temperature range of 0 to 60 degC.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":44692506837080,"sku":"1746-OBP8","price":98.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/2039\/0488\/files\/wm_1_a211a7e2-d4b0-462b-a579-965b8e509e7f.jpg?v=1788282943","url":"https:\/\/www.industriaxplc.com\/id\/products\/allen-bradley-1746-obp8-high-current-dc-output","provider":"IndustriaX Limited","version":"1.0","type":"link"}
