It features four individually isolated channels, configurable for voltage or current ranges including ±10 V, 0–10 V, ±5 V, 0–5 V, 0–20 mA, 4–20 mA, and ±20 mA. The module employs a Sigma-Delta A\/D converter with selectable conversion times of 2.5 ms, 5 ms, or 7.5 ms for all channels. With 16-bit unipolar and 15-bit bipolar resolution, it achieves high accuracy of 0.1% full scale at 25 °C. The module draws 145 mA at 5.1 V and 125 mA at 24 V, while dissipating approximately 3 W. Depending on the terminal base used, it provides continuous isolation of 120 V or 250 V. It supports terminal bases including 1794-TB2, 1794-TB3, 1794-TB3S, 1794-TB3T, and 1794-TBN, making installation flexible. With a temperature range of –20…55 °C and vibration\/shock resistance, the 1794-IF4I is suitable for rugged industrial applications requiring precise analog data acquisition.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDesign: FLEX I\/O isolated analog input module with 4 differential channels.\u003c\/li\u003e\n\u003cli\u003eSignal Support: User-configurable for current (0–20 mA, 4–20 mA, ±20 mA) and voltage (±10 V, 0–10 V, ±5 V, 0–5 V).\u003c\/li\u003e\n\u003cli\u003eResolution: 16-bit unipolar, 15-bit bipolar with Sigma-Delta conversion.\u003c\/li\u003e\n\u003cli\u003eAccuracy: ±0.1% full scale at 25 °C; low drift across temperature.\u003c\/li\u003e\n\u003cli\u003eConversion Rate: Selectable 2.5 ms, 5 ms, or 7.5 ms per module update.\u003c\/li\u003e\n\u003cli\u003eIsolation: Up to 250 V continuous, depending on terminal base used.\u003c\/li\u003e\n\u003cli\u003ePower Requirements: 145 mA at 5.1 V and 125 mA at 24 V DC.\u003c\/li\u003e\n\u003cli\u003eStatus Indicators: Bi-color LED showing power, reset, configuration, and fault states.\u003c\/li\u003e\n\u003cli\u003eMounting: DIN rail or panel mount with compatible FLEX I\/O bases.\u003c\/li\u003e\n\u003cli\u003eEnvironmental Ratings: Operating –20…55 °C, 30 G shock, 5 G vibration, 5–95% RH non-condensing.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 1794-IF4I delivers reliable, isolated, and precise analog input capability for distributed FLEX I\/O systems in industrial automation.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":47105357938986,"sku":"1794-IF4I","price":559.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/s-l1200_e2bf243c-84ed-4be7-bcad-a69fe0ff7191.webp?v=1718448123","url":"https:\/\/iqelectro.com\/products\/allen-bradley-1794-if4i-flex-i-o-4-channel-isolated-analog-input-module","provider":"IQElectro","version":"1.0","type":"link"}
