{"product_id":"allen-bradley-1756-ob16d-discrete-output-module","title":"Allen-Bradley 1756-OB16D Discrete Output Module","description":"\u003cdiv\u003e\u003cp\u003eAllen-Bradley 1756-OB16D is a ControlLogix 16-point DC diagnostic output module that drives 24 V DC loads from a ControlLogix backplane, organized into two 8-point groups with no isolation between individual group outputs. It operates on 19.2–30 V DC and provides up to 2 A per point (with a maximum of 8 A per module, derating to 4 A at 60 °C) and an on-state voltage drop as high as 1.2 V at 2 A. Each point supports a surge of 4 A for 10 ms (repeatable every 1 s), and the module exhibits switching delays of about 60 μs from Off to On and about 630 μs from On to Off. Backplane power consumption is approximately 4.64 W, with internal electronics drawing up to 250 mA from a 5.1 V rail and about 140 mA from a 24 V supply. Diagnostic behavior is maintained in fault and program modes by holding the last state (On or Off), and outputs are electronically fused per point to enhance reliability. The 1756-OB16D accepts removable terminal blocks (1756-TBCH or 1756-TBS6H) and occupies a single rack slot, with operating ambient conditions rated from 0 to 60 °C and 5–95% noncondensing humidity. Electrical isolation is specified between the outputs and backplane as a whole, with no isolation between individual group outputs, and the module includes synchronization capability to the Coordinated System Time within 16.7 s. This device is designed for use in ControlLogix networks to switch DC loads such as relays, indicators, or small actuators, delivering 16 precise, monitorable outputs in a compact form factor suitable for industrial automation applications.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New Surplus No Box","offer_id":51658919346478,"sku":null,"price":509.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_5252e0b6-7ef4-4004-9dbb-c7e5469581e6.jpg?v=1769525547","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-ob16d-discrete-output-module","provider":"PLG Automation ","version":"1.0","type":"link"}
