Product Description: Siemens 6ES7954-8LE03-0AA0

The Siemens 6ES7954-8LE03-0AA0 is a compact power module in the SIMATIC ET 200SP distributed I/O family. It converts 24 V DC supply to a regulated 24 V DC output capable of delivering up to 40 W to downstream ET 200SP modules. Featuring pluggable M12 connection technology, it supports quick installation and simple replacement. Built-in diagnostics ensure reliable operation by signaling undervoltage, overload, and short-circuit conditions. The module is optimized for space-constrained control cabinets and harsh industrial environments.
