In operation, the board functions as the analog input interface that accepts current-loop signals from field sensors and routes them into the automation system’s input channel for monitoring and control of process variables. The part is widely listed and sourced as a Barber Colman MACO accessory under the A-11784 designation, with 33-1107 appearing as the parallel catalog entry on several listings. Since the manufacturer has discontinued this model, buyers typically obtain it from secondary markets or refurbishers, with availability tied to refurbished stock and compatibility with MACO hardware families. \u003c\/p\u003e\u003c\/div\u003e","brand":"Barber","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676665577774,"sku":null,"price":218.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_c73195d3-0081-4369-8aa7-7789ad4a5c74.jpg?v=1769552122","url":"https:\/\/plgautomation.com\/products\/industrial-a-11784-analog-input-board-module-assembly","provider":"PLG Automation ","version":"1.0","type":"link"}
