Siemens 305-05B Rack Mount Programmable Logic Controller

Siemens 305-05B is an eight-slot, rack-mount programmable logic controller rack with an integrated power supply, designed to host TI-305 family modules in automation installations. This chassis consolidates a central controller and expansion I/O into a single 8-slot enclosure, simplifying wiring and cabinet layout for TI-305/Siemens configurations. Equipped with an onboard power supply, the 305-05B provides power to all installed modules, reducing the need for separate power components. It is typically used in compact control panels where a single rack serves as the core of a Siemens TI-305-based control system, offering scalable I/O and modular expansion.
