Siemens 6ES5456-4UA12 Simatic Interface Module

Siemens 6ES5456-4UA12 is a 16-channel digital output module for the SIMATIC S5 family that expands AC switching capability on the backplane of S5 systems. Designed to drive AC loads, each of its outputs supports 115/230 V operation with a maximum of 2 A per channel, and the module is galvanically isolated from the backplane (potenzialgetrennt) to help protect the controller from load transients. This unit is associated with the Digitalausgabe 456 family and is intended for use with S5 configurations such as AG135U/155U, enabling compact, distributed control of actuators like relays, contactors, and solenoids in industrial automation tasks. Compatible with Siemens SIMATIC S5 backplanes, the 6ES5456-4UA12 provides a straightforward, sixteen-point interface for robust digital output control in legacy S5 installations.
