{"product_id":"allen-bradley-1769-if4-compact-i-o-analog-input-module","title":"Allen-Bradley 1769-IF4 4-Channel Analog Input Module","description":"\u003cdiv\u003e\u003cp\u003eAllen-Bradley 1769-IF4 is a Compact I\/O 4‑channel analog input module designed for use in 1769 I\/O racks within CompactLogix systems. It provides four differential or single‑ended analog inputs for voltage or current signals, with selectable ranges including ±10 V, 0–10 V, 0–5 V, 1–5 V, 0–20 mA, and 4–20 mA, all captured by a Delta‑Sigma ADC at 14‑bit resolution (unipolar) or 14‑bit with sign (bipolar). Per channel input impedance is 220 kΩ for voltage or 250 Ω for current, and the module offers isolation of 500 V AC or 710 V DC for 1 minute (group to bus 30 V AC\/30 V DC working voltage). It supports four differential or four single‑ended inputs, and provides durable common‑mode and normal‑mode rejection figures (CMR \u0026gt; 60 dB at 50\/60 Hz with the appropriate filter, NMDR around −50 dB under filter conditions). Physical specifications place the module at roughly 118 mm high, 35 mm wide, and 87 mm deep, weighing about 300 g (0.65 lb). Series B or later units are supported, and the device draws about 60 mA at 24 V (or 120 mA at 5.1 V), with a maximum heat dissipation of 2.52 W. This module is ideal for industrial sensor signal acquisition where four channels must be read into the controller over the 1769 I\/O bus, enabling precise monitoring of analog signals in automation applications. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46243990077674,"sku":null,"price":183.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-079.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/allen-bradley-1769-if4-compact-i-o-analog-input-module","provider":"GTG Hardware","version":"1.0","type":"link"}
