Siemens 6ES5458-7LA11 Programmable Logic Controller Module

Siemens 6ES5458-7LA11 is a SIMATIC S5 digital output module with sixteen isolated relay outputs for the S5-115U/F PLC family. Each channel is rated for 30 V DC and up to 0.5 A, with galvanic isolation between outputs to prevent interference and protect the CPU in backplane configurations. Designed for legacy SIMATIC S5 installations, the 6ES5458-7LA11 slides into the S5-115U/F backplane to provide expanded discrete control of actuators, relays, or other low-voltage loads across a 16‑point channel array. As part of Siemens’ 458-series digital output modules, it delivers reliable, channel-isolated switching suitable for industrial automation tasks that require retrofitting or extension of older S5 systems.
