A built-in 12-bit analog-to-digital converter guarantees precise measurement resolution across all four differential input channels. The module features common isolation, independent channel operation, and a shared return line to simplify field wiring while maintaining robust common-mode noise rejection.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the backplane current consumption of the Schneider ADU 115?\u003c\/p\u003e\n\u003cp\u003eA: The module draws 200 mA from the 5V backplane bus and 40 mA from the 24V field supply.\u003c\/p\u003e\n\u003cp\u003eQ: Does the module support hot-swapping in a live rack?\u003c\/p\u003e\n\u003cp\u003eA: No, power to the rack must be isolated before inserting or removing the module to prevent backplane pin arcing or logic corruption.\u003c\/p\u003e\n\u003cp\u003eQ: What is the update frequency for all four input channels?\u003c\/p\u003e\n\u003cp\u003eA: The hardware updates all four differential channels every 25 milliseconds.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eEnsure the main rack power is fully isolated before mounting the module onto the DIN rail or backplane interface. Connect shielded twisted-pair cables to the terminal block, terminating the shield drain wire strictly at the enclosure ground bar to mitigate electromagnetic interference. Verify that field wiring gauge falls within the 0.2 to 2.5 mm² range prior to securing terminal screws.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":66831307309171,"sku":"ADU 115","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/BIK-114_Cocoai_a6f9ddc6-646c-41ea-bcdd-209e78905035.jpg?v=1791615184","url":"https:\/\/www.dcssupplier.com\/ar\/products\/schneider-adu-115-input-modules","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
