Each channel can be configured for voltage, current, RTD, or thermocouple inputs, with eight differential or single-ended channels that plug into a 1769 Compact I\/O backplane for CompactLogix controllers. Normal operating ranges include voltage inputs of -10 to +10 V, 0 to 10 V, 0 to 5 V, and 1 to 5 V, and current inputs of 0 to 20 mA or 4 to 20 mA, while full-scale ranges extend to ±10.5 V or 0 to 10.5 V for voltage and 0 to 21 mA (or 3.2 to 21 mA) for current. Input impedance is typically 220 kΩ for voltage terminals and 250 Ω for current terminals, and overall accuracy is specified as ±0.2% FS for voltage and ±0.35% FS for current at 25 °C. Isolation and protection features include channel-to-rack isolation of 707 VDC for 1 minute, continuous over-voltage protection to ±30 VDC, and over-current protection to ±40 mA DC, supporting reliable operation in mixed-signal environments. This universal input approach reduces the need for multiple specialized modules, enabling measurement of a broad range of sensors—voltage signals, 4–20 mA loops, TC sensors, and RTDs—within a single 1769 backplane and simplifying wiring and configuration for CompactLogix systems.\u003c\/p\u003e\u003c\/div\u003e","brand":"Spectrum","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51712683147566,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_10fd35a9-1d6d-4ddb-ad63-65fe1fbf54bd.jpg?v=1770361271","url":"https:\/\/plgautomation.com\/products\/spectrum-1769-sc-if8u-analog-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
