High-speed backplane bus communication velocity allows the controller to trigger rapid solid-state state changes without mechanical relay contact bounce. Optical isolation rated at 750 VDC prevents field-side electrical transients from leaking into the backplane logic rail, maintaining control integrity when operating in dense EtherNet\/IP deterministic network topologies across CompactLogix systems.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the 1769-OB32T draw field load power directly from the 1769 backplane bus?\u003c\/p\u003e\n\u003cp\u003eA: No, the backplane bus provides power exclusively for internal module logic circuits. An external 24 VDC power supply must connect directly to the field-side terminal block to drive connected loads.\u003c\/p\u003e\n\u003cp\u003eQ: Can the 1769-OB32T drive alternating current (AC) field loads?\u003c\/p\u003e\n\u003cp\u003eA: No, the module features DC sourcing solid-state transistor outputs rated strictly for 20.4 to 26.4 VDC operation.\u003c\/p\u003e\n\u003cp\u003eQ: How does a sourcing output configuration route current to field devices?\u003c\/p\u003e\n\u003cp\u003eA: Sourcing output points supply positive (+24 VDC) power to the connected load when activated; the return side of the field device wire must connect to the negative (0 VDC) common bus.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the 1769-OB32T onto a standard 35 mm DIN rail or directly to a panel backplate using mounting screws. Ensure the module locks securely into adjacent 1769 modules via the integrated tongue-and-groove bus connectors and locking levers. Strip field wiring conductors to specified lengths before securing them into the Removable Terminal Block (RTB). Route field load wiring separately from low-level analog or communication cables inside the wire ducts to prevent electromagnetic coupling. Connect the external 24 VDC field power supply to the designated power terminals on the RTB, verifying correct polarity prior to energizing the bus.\u003c\/p\u003e","brand":"Allen Bradley","offers":[{"title":"Default Title","offer_id":43166061035610,"sku":"1769-OB32T","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/466.jpg?v=1775031518","url":"https:\/\/www.spareoil.com\/products\/1769-ob32t-allen-bradley-compactlogix-32-point-output-module","provider":"SpareOil Automation","version":"1.0","type":"link"}
