SIEMENS SIMATIC S5 6ES5466-3LA11

SIEMENS SIMATIC S5 6ES5466-3LA11 – Analog Input Module for S5 PLC Systems

The Siemens SIMATIC S5 6ES5466-3LA11 is an analog input module designed for use in industrial automation systems based on the SIMATIC S5 programmable logic controller series. This module is intended for precise and flexible measurement of analog signals such as voltage and current from field sensors and transmitters. It is suitable for integration into process control, manufacturing, and monitoring systems that require accurate data acquisition.

The module provides 16 single-ended or 8 differential analog input channels. The inputs are floating, which means they are galvanically isolated from the system ground and from each other. This design significantly improves signal integrity by preventing interference and eliminating ground loop problems, especially in electrically noisy industrial environments.

The 6ES5466-3LA11 supports multiple signal types and ranges, including 0 to 20 mA, 4 to 20 mA, ±20 mA, 0 to 10 V, ±10 V, and other variants. This flexibility makes it possible to connect various sensor types without the need for signal conditioning. The module features high-resolution analog-to-digital conversion, allowing precise processing of low-level analog inputs.

It is compatible with several models of the SIMATIC S5 series, including the S5-115U, S5-135U, and S5-155U systems. The module is inserted into the appropriate rack and configured using the standard S5 engineering tools.
