Siemens 6ES5441-7LA11 Programmable Logic Controller Module

Siemens 6ES5441-7LA11 is a SIMATIC S5 digital output module for the S5-115U/H PLC family. It delivers 32 output channels that switch 24 V DC loads at up to 0.5 A per channel, enabling direct actuation of devices such as relays and indicator loads within classic Siemens S5 automation configurations. As part of the 6ES5441 family, this 32-DO module is used to expand discrete I/O on S5-115U/H systems, with the 7LA11 designation identifying the 32 DO, 24 V DC variant. Common applications include machine control and process automation where compact, modular digital outputs are required for controlling 24 V devices in automation panels. When integrating a used or surplus unit, verify compatibility with your S5 CPU model and backplane configuration and follow Siemens installation guidelines for safe wiring and protection.
