Siemens 6ES5 466-3LA11 Programmable Logic Controller Module

Siemens 6ES5 466-3LA11 is an eight-channel floating analog input module for the SIMATIC S5 family, designed to plug into S5-115U/H/F and S5-135U/155U CPUs to convert sensor signals into digital values for the PLC. It provides eight isolated analog input channels (floating) for monitoring process variables with isolation between inputs. The module supports voltage inputs up to 10 V and current inputs in the 4–20 mA range, with documented input-range options including 1.25 V, 2.5 V, 5 V, and 10 V to accommodate different sensors. This I/O expansion enables reliable analog signal acquisition in compatible Siemens S5 installations without altering digital channels.
