Allen-Bradley 1734-IB8K POINT I/O Input Module

Allen‑Bradley 1734-IB8K POINT I/O input module is an 8-channel digital input block for 24 VDC sinking signals in the POINT I/O family. Each of its eight channels accepts 24 VDC field signals wired as sinking inputs and reports status to the POINT I/O backplane; the module is conformally coated for harsher industrial environments. Wiring uses a common 24 VDC supply and can be daisy-chained via the POINT I/O adapter, 1734-FPD, 1734-EP24DC, or an external auxiliary terminal block, enabling shared power and common returns across modules. The 1734-IB8K is designed for standard 24 VDC sensors and switches and is part of Rockwell Automation’s scalable, distributed I/O system that preserves fast, deterministic backplane communication. ON-state voltage ranges from 10 to 28.8 V and ON-state current is typically 2 to 5 mA per channel, per the module’s sinking input characteristics. In the POINT I/O ecosystem, this conformal coated variant offers environmental protection for installations subject to moisture or contaminants while maintaining compatibility with 1734 POINT I/O rack architectures and common power distribution via 1734-FPD or EP24DC connections.
