Siemens 6ES7400-0HR54-4AB0 SIMATIC S7-400H CPU 417-5H System Bundle DC UR2-H Redundant PLC

The Siemens 6ES7400-0HR54-4AB0 is a SIMATIC S7-400H redundant system bundle built around two CPU 417-5H 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 carries the largest CPU offered in this S7-400H bundle line; choose it when the application already saturates the memory or scan-time budget of the lower-numbered CPU bundles. 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.
