Allen-Bradley 149V-DHL666 C01 Digital Input Module

Allen-Bradley 149V-DHL666 C01 Digital Input Module is a digital I/O interface card used in Rockwell Automation control systems to read discrete signals from field devices and present them to the PLC for processing. With the exact part number 149V-DHL666 C01, this module is part of Allen-Bradley’s digital input family and is designed to mount in a compatible I/O rack or chassis that is powered and scanned by a Rockwell controller. In typical automation applications, digital input modules capture on/off states from sensors, switches, and other binary devices, enabling logic routines, fault detection, and monitoring within the control system. The 149V-DHL666 C01 designation identifies a specific configuration and revision, underscoring the need to verify backplane compatibility, channel count, and electrical characteristics against your controller and rack layout. For precise specifications, wiring conventions, and supported backplane standards, consult the official Allen-Bradley documentation for the 149V-DHL666 C01 to ensure correct integration with your controller, I/O configuration, and safety requirements.
