It accepts a 10–31.2 VDC input range (nominal 24 V) and wires via removable terminal blocks (1756‑TBCH or 1756‑TBS6H) to the 36‑pin backplane interface. Each channel sinks field current to the backplane, with a backplane current draw of 120 mA at 5.1 V and 2 mA at 24 V, and a module power dissipation up to 6.2 W at 60 °C (0.66 W backplane power). Electrical specs per channel include an on‑state current of 4.8–5.5 mA across the 10–31.2 V range, and an off‑state current up to 2.27 mA with off‑state voltage not exceeding 5 V; input impedance is about 5.67 kΩ. Input timing comprises a hardware delay of up to 380 μs from Off‑to‑On, plus an optional filter of 0, 1, or 2 ms; for On‑to‑Off, a hardware delay of up to 420 μs plus an optional filter of 0, 1, 2, 9, or 18 ms. The 32 inputs are arranged in two 16‑channel groups, making dense I\/O layouts straightforward for ControlLogix applications. This module is used to read multiple digital sensors and switches in automation systems, offering reliable, isolated DC inputs within a single 1756 chassis.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51658933141806,"sku":null,"price":362.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_688dd732-8afb-4059-92b7-48ada513e48e.jpg?v=1769525708","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-ib32-dc-input-module-for-controllogix","provider":"PLG Automation ","version":"1.0","type":"link"}
