Siemens 6ES5458-7LC11 PLC Analog Input Module

Siemens 6ES5458-7LC11 is a 16-channel floating digital output module for the SIMATIC S5 family, designed to drive external loads through isolated relay contacts in S5-115U/F installations. It provides 16 floating relay outputs that are isolated from the backplane, allowing load circuits to be switched independently from the controller supply. The module supports AC switching up to 250 V at 1.5 A per channel, and DC switching with ratings of 30 V DC at up to 1 A or 110 V DC at up to 0.08 A, enabling control of indicators, relays, or actuators in industrial automation. Specifically matched for use with the S5-115U/F backplane, this part integrates into legacy Siemens systems to expand discrete, isolated output capability in a compact form factor. The 6ES5458-7LC11 is identified by Siemens as a digital output module that complements the S5-115U/F control configuration, providing reliable relay-based control where high-side isolation and straightforward channel-by-channel switching are required.
