Allen-Bradley 1715-TADIF16 1715 Duplex AI Termination Assembly
The Allen-Bradley 1715-TADIF16 is a 16-channel analog input duplex termination assembly designed for the 1715 Redundant I/O system platform. 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.
Dual-Module Signal Routing & Electrical Protection
The 1715-TADIF16 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.
Galvanic 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.
Hardware Installation & Terminal Connections
Designed for installation on a 35 mm DIN rail, the termination assembly interfaces directly with the 1715-A3IO base unit. Field connections accommodate shielded copper cables to minimize electromagnetic interference across sensitive analog measurement paths.

Frequently Asked Questions
Q: What is the functional difference between the 1715-TASIF16 and 1715-TADIF16 termination assemblies? 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.
Q: 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.
