It acts as the physical field-wiring interface for two redundant 1715-IF16 16-channel analog input modules, enabling fault-tolerant 4-20 mA current loop monitoring in critical industrial process applications. The assembly routes incoming field signals in parallel across both module slots, ensuring uninterrupted system telemetry during hot-swapping or individual module maintenance.\u003c\/p\u003e\n\u003ch3\u003eDual-Module Signal Routing \u0026amp; Electrical Protection\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003e1715-TADIF16\u003c\/strong\u003e supports 16 independent analog input channels operating over an 18 to 32 VDC field power range. Each signal channel is protected by an individual 50 mA, 125 V Type T fuse to prevent overcurrent events from damaging sensitive module circuitry or disrupting adjacent process loops.\u003c\/p\u003e\n\u003cp\u003eGalvanic safety is maintained via 50 V continuous basic insulation between the field I\/O ports and the system backplane bus, with withstand capabilities type-tested at 500 VAC for 60 seconds. In addition, the duplex configuration provides 50 V isolation between individual input channels. The assembly dissipates up to 4.0 W of system power with an additional field loop dissipation rating of 0.075 W per channel.\u003c\/p\u003e\n\u003ch3\u003eHardware Installation \u0026amp; Terminal Connections\u003c\/h3\u003e\n\u003cp\u003eDesigned for installation on a 35 mm DIN rail, the termination assembly interfaces directly with the 1715-A3IO base unit.

A: The 1715-TASIF16 is a simplex termination assembly designed to interface a single 1715-IF16 module without channel-to-channel isolation. The 1715-TADIF16 is a duplex assembly that supports two redundant 1715-IF16 modules side-by-side while providing 50 V galvanic isolation between individual channels.\u003c\/p\u003e\n\u003cp\u003eQ: Are the individual channel fuses on the 1715-TADIF16 field-replaceable? A: Yes. Each of the 16 analog input channels contains an inline 50 mA, 125 V Type T fuse to protect the loop from field-side short circuits or overvoltage conditions.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":53162541056280,"sku":"1715-TADIF16","price":270.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/1715-TADIB16D_Cocoai.jpg?v=1793933528","url":"https:\/\/www.innoplcsync.com\/products\/allen-bradley-1715-tadif16-1715-duplex-ai-termination-assembly","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
