Siemens AG 6ES5-458-7LA11 Relay Output Module

Siemens 6ES5-458-7LA11 Relay Output Module is a 16-channel relay-output card for the SIMATIC S5 PLC family, commonly paired with the S5-115U/F controllers to switch discrete field loads. Each channel provides a relay contact that can interface with actuators, signaling devices, or other external equipment, expanding the PLC’s output capability beyond solid-state I/O. The device is catalogued as 6ES54587LA11 and is also listed under 6ES5-458-7LA11, offering a 16-channel relay output with per-channel ratings described as 30 V DC at up to 0.5 A. This module enables independent control of multiple loads from a single S5 rack, making it suitable for legacy automation panels that require relay switching for devices such as valves, solenoids, lights, or indicators.
