It accepts thermocouples of J, K, T, E, R, S, B, N, C, and D types as well as low-level millivolt signals, with each channel isolated from the others and from the backplane to minimize noise and cross‑channel interference. The module provides 16-bit resolution per channel, a sigma-delta ADC, and an 8 Hz channel bandwidth with a 500 ms update time, enabling stable temperature measurements for process control. Isolation ratings include 1000 V transient and 150 V AC continuous between channels and to the backplane, supporting rugged industrial environments; common‑mode rejection is better than 120 dB at 50\/60 Hz with a 1 kΩ imbalance. It occupies any I\/O slot except slot 0 in the SLC 500 chassis, and draws about 110 mA from a 5 V supply or 85 mA from a 24 V supply, with a maximum power of 0.6 W. Calibration is typically yearly if required. This module is commonly used for temperature monitoring and other low-voltage sensor measurements where isolated inputs improve accuracy in noisy settings. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51659712790830,"sku":null,"price":279.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_6f0f833e-4652-4f7f-998f-d5be18d757b8.jpg?v=1769529793","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1746-int4-isolated-analog-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
