Siemens T1305-01N 24V DC Digital Input Module Industrial

The Siemens T1305-01N is a 24V DC digital input module designed for industrial PLC applications, providing a dedicated interface to capture external 24V logic signals and feed them into a Siemens controller. Listed as a replacement part for the SIMATIC 305-10N input module, the T1305-01N preserves 24 V DC input functionality for existing 305-series installations, allowing maintenance or upgrade without changing the backbone hardware. As a digital input module, it is intended to sense devices such as industrial sensors, limit switches, and other 24V DC devices, enabling the PLC to monitor field conditions and trigger appropriate control actions. When retrofitting or designing a 305-series automation system, it is important to confirm that the T1305-01N’s electrical interface and physical form factor match the existing I/O rack so that signals are read reliably and the module can be mounted securely. Typical installations include machine controls, conveyors, and packaging lines where 24V sensing is common.
