Each channel accepts a 24 V DC signal in the 10–28.8 V nominal range (on-state), drawing about 2–4 mA per channel at 24 V, with off-state voltage limited to 5 V and off-state current at least 1.5 mA. The module’s input impedance is up to 4.7 kΩ, and total power dissipation is 0.7 W maximum at 28.8 V. It communicates via the POINT Bus, with a maximum PointBus current of 75 mA from the 5 V-side supply. The 1734-IB2 mounts in a 1734 chassis using a base such as 1734-TB, 1734-TBS, 1734-TOP, or 1734-TOPS, and its field wiring is isolated from the backplane according to the 1734 family specifications. Field power for the inputs is supplied from a 24 V dc source in the nominal 24 V range. The module measures two digital inputs and is commonly used to sense devices such as limit switches, proximity sensors, and other 24 V DC sensors in machine automation and conveyor applications where reliable, inexpensive digital sensing is required.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51659004051758,"sku":null,"price":290.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_1aac6f0a-a2da-4264-8d5d-10f29f06a3c2.jpg?v=1769526499","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1734-ib2-2-point-digital-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
