Each channel accepts a loop-powered 4-20 mA signal and converts it to a digital value for the host controller, enabling monitoring of multiple process signals from a single module. The module is Multibus-compatible and supports sixteen independent current inputs, suitable for scaling sensor networks in batch or continuous processes. In certain installations, an external power supply may be required to drive the 4-20 mA transmitters connected to the inputs. Typical applications include process monitoring, data acquisition, and instrumentation retrofits in manufacturing environments where AB-compatible analog input modules interface with legacy AutoMax\/Automate controllers.\u003c\/p\u003e\u003c\/div\u003e","brand":"Reliance","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51708577841454,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_b4a6a69b-e954-4823-b3c6-98228e9bd470.jpg?v=1770246385","url":"https:\/\/plgautomation.com\/products\/reliance-61c540a-analog-input-current-module","provider":"PLG Automation ","version":"1.0","type":"link"}
