Siemens 6ES5955-3LC13 Programmable Logic Controller Module

Siemens 6ES5955-3LC13 is a SIMATIC S5 power-supply module designed for the 135U/155U backplane racks. It accepts AC power in 115 V or 230 V and provides a regulated +5 V DC supply to the backplane and connected modules, delivering up to 18 A on the +5 V rail. The module mates with the MPC interface via a Subminiature D 25-pin connector, and its installation documentation covers wiring and integration with the S5 system. Physically, the unit measures roughly 330 mm high by 440 mm long by 110 mm wide and weighs about 4 kg; as a legacy Siemens part, it is commonly found in used or refurbished condition for maintenance or retrofits of older S5-based controls.
