Each of its 16 channels accepts current input in the -20 to +20 mA range, enabling bidirectional measurement of common 4-20 mA loops and providing headroom for fault conditions. The module provides galvanic isolation between the analog inputs and the backplane, rated up to 500 V AC for 1 second, helping protect the controller from surges and ground loops. Wiring is performed through two common terminals on the module, supporting consistent wiring for standard 2-wire current sensors. In operation, the NI16I presents 16 independent input values to the PLC’s I\/O image (one word per channel), enabling high-density monitoring within a single module. Designed for use in a 1746 backplane chassis with SLC 500 controllers, this module is well-suited for applications such as flow meters, pressure transducers, and other analog signals that are provided as 4-20 mA current loops, particularly where channel-to-channel isolation and noise rejection are important.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New Surplus No Box","offer_id":51658973446446,"sku":null,"price":42.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_3a913c46-e00a-4a4d-874f-83d453d283fe.jpg?v=1769526200","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1746-ni16i-isolated-analog-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
