It accepts 74–132 V AC signals (47–63 Hz) with a nominal 120 V AC rating, and provides 125 V continuous isolation between inputs and the backplane as well as between the two input groups (with no isolation between individual inputs within a group). Termination is via removable blocks (1756-TBNH or 1756-TBSH), and the module supports debounced, timestamped sensing with configurable timing—off-to-on delays up to 10 ms with a 1–2 ms filter and on-to-off delays up to 8 ms with a 9–18 ms filter—plus input timestamps within ±200 µs and a cyclic update time of 200 µs to 750 ms. Electrical and thermal data include a backplane Power draw of 0.58 W and a maximum dissipation of 5.8 W at 60 °C, an input impedance of about 10.15 kΩ at 132 V AC, and operating currents of 5–13 mA when active with up to 2.5 mA in the off state. The card fits a 1-inch slot width, supports electronic module keying, and uses standard Rockwell RTBs in open-style enclosures, with North American temperature rating of T4. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51658942578990,"sku":null,"price":361.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_5475ec10-513c-4362-8735-5d8465b213ad.jpg?v=1769525748","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-ia16-isolated-analog-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
