This digital module operates within a voltage range of 10 to 60 VDC, providing reliable solid-state switching for industrial control devices such as solenoids, indicators, and motor starters. It requires compatibility with a Series B 1771 I\/O chassis and supports flexible addressing configurations depending on system architecture.\u003c\/p\u003e\n\u003cp\u003eEquipped with optical isolation between the logic side and the load side, the 1771-OBD ensures robust noise immunity and electrical protection in harsh manufacturing environments. Front-panel diagnostic indicators include a green module status LED, 16 individual red point status LEDs for direct logic-side verification, and a dedicated red fuse-blown indicator linked to onboard fusing protection. The module is engineered to handle moderate inrush currents while maintaining low on-state voltage drops for efficient power delivery.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e16 sourcing-type DC output channels operating at 10 to 60 VDC\u003c\/li\u003e\n  \u003cli\u003eDelivers up to 2 A of continuous output current per point, with an 8 A maximum per module\u003c\/li\u003e\n  \u003cli\u003eHandles surge currents up to 4 A per output for 10 ms, repeatable every 2 seconds\u003c\/li\u003e\n  \u003cli\u003eProvides optical isolation rated at 1,500 VAC rms between I\/O and backplane\u003c\/li\u003e\n  \u003cli\u003eFeatures comprehensive diagnostic LED indicators for module health, individual channel status, and blown fuse alerts\u003c\/li\u003e\n  \u003cli\u003eLow on-state voltage drop of 0.3 V max at 2 A for improved thermal and electrical efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDirectly driving pilot lights, control relays, and solid-state actuators in PLC-5 architectures\u003c\/li\u003e\n  \u003cli\u003eSwitching inductive and resistive DC loads within manufacturing and process control skids\u003c\/li\u003e\n  \u003cli\u003eInterfacing with complementary 1771 input modules requiring shared DC common references\u003c\/li\u003e\n  \u003cli\u003eExpanding discrete output capacity in legacy 1771 universal I\/O chassis configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eParameter\u003c\/th\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\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\u003eModule Type\u003c\/td\u003e\n      \u003ctd\u003eDC Output Module\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Family\u003c\/td\u003e\n      \u003ctd\u003ePLC-5 \/ 1771 Universal I\/O\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCatalog Number\u003c\/td\u003e\n      \u003ctd\u003e1771-OBD\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOutputs per Module\u003c\/td\u003e\n      \u003ctd\u003e16 (sourcing)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOperating Voltage Range\u003c\/td\u003e\n      \u003ctd\u003e10 to 60 VDC\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOutput Current Rating\u003c\/td\u003e\n      \u003ctd\u003e2 A max per output, 8 A max per module\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMinimum Load Current\u003c\/td\u003e\n      \u003ctd\u003e2.5 mA per output\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMax Surge Current\u003c\/td\u003e\n      \u003ctd\u003e4 A per output for 10 ms\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBackplane Current Draw\u003c\/td\u003e\n      \u003ctd\u003e400 mA at 5 VDC (+\/- 5%)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSignal Delay\u003c\/td\u003e\n      \u003ctd\u003e1.0 ms on or off\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eIsolation Voltage\u003c\/td\u003e\n      \u003ctd\u003e1,500 VAC rms\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCountry of Origin\u003c\/td\u003e\n      \u003ctd\u003eUnited States\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompliance and Certifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eUL Listed Industrial Control Equipment\u003c\/li\u003e\n  \u003cli\u003eCSA Certified\u003c\/li\u003e\n  \u003cli\u003eCE Compliant for applicable directives\u003c\/li\u003e\n  \u003cli\u003eC-Tick marked\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":53770299703659,"sku":"1771-OBD","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3227\/0443\/files\/1771-OBD_1200x1200_a2aef2db-48e1-4f28-beff-097e25d104e6.jpg?v=1787740629","url":"https:\/\/www.plcprotech.com\/products\/allen-bradley-1771-obd-plc-5-dc-output-module","provider":"PLC ProTech Ltd.","version":"1.0","type":"link"}
