Operating from 74–132 VAC at 47–63 Hz, each input is conditioned through internal rectification to feed the logic side, and the module uses a 20-pin removable terminal block arranged as two 8-point groups. Power and timing characteristics include a backplane current\/consumption profile of about 0.58 W total backplane power, with typical draws of 100 mA at 5.1 V and 2 mA at 24 V, and a maximum dissipation of 5.8 W at 60 °C (18.41 BTU\/hr). Electrical specs show an off-state voltage up to 20 V and off-state current up to 2.5 mA; on-state current ranges from 5 mA minimum at 74 V AC to 13 mA maximum at 132 V AC, with inrush up to 250 mA peak decaying to \u0026lt;37% in 22 ms without activation. Timing features include an off-to-on hardware delay of up to 10 ms plus a user-selectable input filter of 1 ms or 2 ms, and an on-to-off delay of up to 8 ms with a 9 ms or 18 ms filter. Firmware support includes v3.004 family compatibility. Typical applications involve interfacing 120 VAC field signals—such as switches, relays, and sensors—into ControlLogix controllers for general-purpose automation, machine control, and process monitoring. The module is compatible with the ControlLogix 1756 backplane and uses a removable, 20-pin terminal block to connect the 16 inputs. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658941923630,"sku":null,"price":899.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_e3f762f4-2a8c-40e1-9d5e-3bb1b2bd5841.jpg?v=1769525745","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-ia16-16-point-120v-ac-digital-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
