Each channel delivers a calibrated 0–21 mA current with 13‑bit resolution across the full range, and the module offers 250 V continuous isolation between the output circuitry, backplane, and field connections. Series A hardware (1756-OF6CI\/A) uses a monotonic R‑ladder DAC for current output, with no open-circuit detection, short-circuit protection limited to 21 mA, and 24 V DC overvoltage protection, along with a module scan time of up to 25 ms (10 ms for integer data paths). Total backplane power is approximately 6.7 W for 0–550 Ω loads or 8.5 W for 551–1000 Ω loads, with backplane current around 250–300 mA depending on the load, and the unit uses a removable 20‑pin terminal block (1756-TBNH) for field connections.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658917675310,"sku":null,"price":874.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_fd2e84ae-c9bb-46f6-9afc-aa03ab67f7d0.jpg?v=1769525523","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-of6ci-a-analog-output-module","provider":"PLG Automation ","version":"1.0","type":"link"}
