PLCs, Power Supplies & Others

The 6ES5252-4BA11 functions as a central processor module within SIMATIC S5 automation racks. This unit executes control logic, manages memory operations, and coordinates data flow across connected I/O cards. Consequently, engineers rely on it for deterministic machine control in demanding factory settings.

Technical Specifications at a Glance

The 6ES5252-4BA11 combines compact dimensions with robust industrial construction. Moreover, its parameter set supports accurate planning for cabinet layout and power budgeting.

Interface and Bus Communication

The 6ES5252-4BA11 communicates through the S5 parallel backplane bus. Therefore, it exchanges data rapidly with digital and analog modules. The single-board design reduces connector count and simplifies troubleshooting. In addition, the module draws 5 V DC directly from the rack power rail.

Physical Dimensions and Installation

This processor occupies one standard slot in an S5 rack. Furthermore, its 20 mm width preserves space for additional modules. The 6ES5252-4BA11 weighs approximately 0.5 kg. Consequently, installation requires no special lifting equipment. Technicians simply align the board, then secure it with the front retaining screw.

Memory Retention and Energy Storage

A buffer battery preserves RAM contents during power interruptions. Accordingly, the 6ES5252-4BA11 retains program data without external uninterruptible supplies. Battery replacement follows a scheduled maintenance interval. Therefore, plant teams should track cell voltage during routine inspections.
