It supports input ranges of -10 to +10 V, 0 to 20 mA, and 4 to 20 mA, and offers 16 to 21-bit resolution depending on configuration. The module provides robust noise rejection with normal-mode \u0026gt;80 dB and common-mode \u0026gt;100 dB at 50\/60 Hz, and it includes overvoltage protection of up to 30 V DC on voltage inputs and 8 V DC on current inputs. Calibrated accuracy is better than 0.05% of range for voltage and 0.15% of range for current, with a calibration interval of 12 months, and an open-circuit detection time of full-scale within 5 seconds. Backplane power is 4.77 W total, drawn from a 5.1 V DC\/300 mA and 24 V DC\/135 mA supply arrangement. These eight differential channels are suited for interfacing with HART-enabled transmitters in process control or automation applications, enabling simultaneous transmitter communication while delivering precise measurements to the ControlLogix controller.\u003c\/p\u003e\n\u003cspan\u003e \u003c\/span\u003e\n\u003c\/div\u003e","brand":"Spectrum","offers":[{"title":"New","offer_id":51712683639086,"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_566e8899-d046-4f2e-8524-5451823d227c.jpg?v=1770361285","url":"https:\/\/plgautomation.com\/products\/spectrum-1756sc-if8h-analog-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
