Siemens 6ES7400-0HR53-4AB0 SIMATIC S7-400H CPU 416-5H System Bundle DC UR2-H Redundant PLC

The Siemens 6ES7400-0HR53-4AB0 is a SIMATIC S7-400H redundant system bundle built around two CPU 416-5H controllers. It ships with one UR2-H rack, 2x PS 405 10A, 24/48/60 V DC, four synchronization modules for cable runs up to 10 m, and two 1 m sync cables; the memory cards and backup batteries needed to complete the H-system pair are ordered separately.

Selection Notes

This bundle sits between the smaller and larger CPU bundles in the S7-400H line; drop to the lower-numbered CPU bundle if the application is lighter, or step up to the largest CPU bundle in the line if headroom is tight. All four synchronization modules needed to link the redundant CPU pair ship in the box, so no separate sync hardware has to be sourced when building the H-system. The included PS 405 supplies run on 24/48/60 V DC, so this variant suits sites with DC distribution already in place; the AC-supply version of the same CPU bundle covers 120/230 V AC installations instead.
