Product Description: Siemens 6ED1055-1NB10-0BA2

The Siemens 6ED1055-1NB10-0BA2 is a compact DIN-rail power supply designed specifically for the LOGO! 8 modular logic platform. It accepts a universal mains input (120 … 240 V AC or DC) and delivers a stable 24 V DC at up to 0.3 A to feed the LOGO! base module and optional I/O extensions. Integrated protection functions and buffering ensure reliable operation in industrial environments.
