Allen-Bradley 1732DS-IB8 Digital Input Module

The Allen-Bradley 1732DS-IB8 is a Guard I/O 8-point digital input module built for DeviceNet networks as part of the ArmorBlock safety I/O family. It provides eight independent 24V DC digital inputs and eight test outputs, enabling safe-state signaling and self-test capabilities within a single compact card. This safety input module is designed to interface directly with safety devices such as interlocks, safety gates, and emergency-stop circuits and to report their status over DeviceNet to a safety controller or Guard I/O bus. Firmware for the 1732DS-IB8 is available as version 1.053, ensuring compatibility with current Rockwell Automation software ecosystems and allowing firmware updates to address safety logic and diagnostics. Typical applications include machine guarding on production lines, automated safety gates, and guarded access points where reliable monitoring of multiple safety signals is required. The 1732DS-IB8 communicates over DeviceNet, integrating with ArmorBlock’s guarded I/O topology to deliver deterministic input data to the control system while maintaining isolation and safety integrity. With eight inputs and eight test outputs, this module supports fault indication and test signaling within safety-critical loops, and its ArmorBlock platform is designed for on-machine deployment in industrial environments.
