Allen-Bradley 194E-E-PD10 Industrial I/O Module

Allen-Bradley 194E-E-PD10 is a single normally open auxiliary contact block for 194E IEC load switches, configured for early closing (PD10) to provide a signaling contact alongside the main switching element. This 194E accessory adds one NO auxiliary contact to 194E-series devices, enabling independent status feedback or interlock signaling in control circuits for industrial panel applications. As part of the 194E family from Rockwell Automation, the PD10 accessory is used with 194E load-switch assemblies in 25–100 A ratings, helping engineers monitor switch state and coordinate sequencing without loading the main current path. Typical applications include feeding a PLC or safety interlock with a closed-state signal and supporting control logic in machine automation, while preserving the primary switch’s load-handling capability. The PD10 designation identifies the option as a 1 NO, early-closing auxiliary contact block compatible with the 194E ecosystem, and it is documented in 194E literature as the auxiliary contact accessory for this family.
