Each channel can be configured to accept either voltage or current input, covering ranges such as 0-5 V, 0-10 V, -10 to +10 V, 0-20 mA, 4-20 mA, and -20 to +20 mA, enabling flexible sensing of a wide variety of industrial signals from temperature sensors, flow meters, level transducers, and other analog devices. The module uses 16-bit analog-to-digital conversion on every channel, providing finer granularity than older, lower-resolution analog cards, and the acquired values are accessible to the CPU through the standard SLC 500 I\/O image table. Designed to plug into a Rockwell Automation SLC 500 backplane, the NI4 supports typical expansion in legacy systems as well as new installations that require direct compatibility with Allen-Bradley hardware. Applications include process monitoring, instrumentation, and control loops that rely on multiple analog inputs in a compact 4-channel format, ideal for panel installations where channel density matters and wiring remains straightforward with standard backplane connections. As with other NI-series modules, setup involves selecting the channel ranges in software or configuration data and reading the converted values in your ladder or structured text logic, enabling precise monitoring and reliable control decisions based on four concurrent analog measurements.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51659712037166,"sku":null,"price":1879.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_c7377ccd-3f43-4027-86f3-29c95f04ee86.jpg?v=1769529789","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1746-ni4-4-channel-high-resolution-analog-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
