The module accepts input voltages within a ±5 V range and delivers isolated, conditioned voltage data to the host control system, helping to minimize ground loops and electrical noise that can affect measurement accuracy. As a voltage-input module, it serves as the interface between sensors or transducers that generate small analogue voltages and the controller’s data path, enabling reliable monitoring of process variables without transferring power or noise from the field side to the logic side. Its isolation and voltage-input configuration support robust operation in industrial environments, where transients and noise can otherwise corrupt signals seen by the control system. Referenced in Analog Devices’ 3B30\/3B31 Isolated Voltage Input documentation, the 3B31-02 is defined as an isolated input module with a ±5 V input specification, intended for applications requiring signal integrity and safety through electrical isolation in industrial process-control installations.\u003c\/p\u003e\u003c\/div\u003e","brand":"ANALOG","offers":[{"title":"New","offer_id":51659996201262,"sku":null,"price":91.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_59cd5c0c-2038-4bc7-9181-209ee5c41c04.jpg?v=1769531512","url":"https:\/\/plgautomation.com\/products\/analog-3b31-02-industrial-process-control-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
