Core Performance and Selection Advantages

The PP836 delivers significant engineering and operational value in modern System 800xA architectures. Compared to older ABB power supplies (e.g., PP831), it offers higher power density (10 A in a compact form factor), improved thermal efficiency (>88% at full load), and enhanced diagnostic granularity. Its ability to operate in true redundant mode—where two units share load and automatically compensate for a failure without voltage sag—ensures uninterrupted I/O operation, which is critical for SIL-rated or continuous-process applications.

A key functional advantage is its native integration with the AC 800M controller. Unlike generic industrial PSUs, the PP836 reports real-time status (input voltage, output current, fault codes) directly into the 800xA control network. This enables predictive maintenance—such as alerting operators to gradual capacitor degradation before failure—and simplifies troubleshooting during commissioning. From a total cost of ownership (TCO) perspective, the hot-swap capability eliminates the need for system shutdowns during replacement, reducing downtime risk. Additionally, its universal input range removes the need for external transformers in global deployments, streamlining procurement and panel design.

System Integration and Expandability

The PP836 is engineered for seamless integration within the ABB System 800xA ecosystem. It is configured and monitored through ABB Automation Builder (or legacy Control Builder M), where power supply health appears alongside I/O and logic modules in the hardware tree. This unified engineering environment reduces configuration errors and accelerates system validation.

In terms of networking, while the PP836 itself does not handle fieldbus traffic, it powers communication modules (e.g., CI854 for PROFIBUS, NI801 for Ethernet) that support PROFIBUS DP, PROFINET, Modbus TCP, and IEC 61850. The stable, low-noise 24 VDC output ensures reliable signal integrity for sensitive digital and analog I/O, which indirectly supports robust connectivity to SCADA, MES, and cloud platforms via OPC UA servers embedded in the 800xA architecture.

Regarding scalability, a single 800xA I/O chassis can accommodate up to two PP836 modules for full redundancy. Multiple chassis can be daisy-chained from a common AC distribution panel, enabling large-scale I/O expansions (thousands of points) without power bottlenecks. The module’s mechanical design aligns with ABB’s modular philosophy—adding or replacing power capacity requires no rewiring, only insertion into the backplane. This modularity, combined with long-term product availability commitments from ABB, makes the PP836 a low-risk choice for projects with 15+ year operational horizons.
