It supports diagnostic status in groups of four, offering 8 groups of 4 diagnostic points for health monitoring. Electrical characteristics include operating voltage 74–132 VAC (nominal 120 VAC), input impedance up to 14 kΩ at 132 V AC \/ 60 Hz, off-state voltage max 20 V, off-state current max 2.5 mA, and on-state current range of 5–15 mA depending on input voltage (74–132 VAC). Maximum power dissipation is 6.1 W at 60 °C, with internal current draw of about 165 mA at 5.1 V and 2 mA at 24 V. Input response delays follow the data sheet: OFF→ON delay 1.5 ms nominal, 10 ms max with a user-selectable input filter time of 1 or 2 ms; ON→OFF delay 1 ms nominal, 8 ms max with a user-selectable filter time of 9 or 18 ms. This module is designed for use in standard ControlLogix racks and communicates via the 1756 I\/O backplane, making it suitable for digital input sensing on AC-powered field devices in industrial automation systems.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51659675697454,"sku":null,"price":476.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_5c40bf9a-571c-47d7-9873-63d5539d9e5c.jpg?v=1769529711","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-ia32-controllogix-io-module","provider":"PLG Automation ","version":"1.0","type":"link"}
