Backplane Bus Communication and I/O Density Scaling
The power supply module mounts directly into the backplane of the 560MPR03 or 560SFR02 subracks, feeding regulated power lines directly into the system bus. This centralized voltage delivery directly dictates the system's I/O density scaling, determining the number of active communication and peripheral modules running simultaneously on the backplane. To maintain deterministic synchronization under peak traffic configurations, the power rail must interface with processing elements running matching firmware flash compatibility levels, preventing voltage-dip frame dropouts during heavy cyclic processor demands.
Frequently Asked Questions
Q: How is automatic failover achieved in a redundant configuration?
A: Redundancy is established by installing two 560PSU01 units in parallel within the subrack. The modules employ internal diode auctioneering and automatic load-sharing circuits; if one unit drops below nominal voltage parameters, the parallel unit instantly assumes the full current load without backplane interruption.
Q: What are the limits of the integrated galvanic isolation on this unit?
A: The module enforces absolute galvanic isolation between the high-voltage 110-220 V DC input terminals and the low-voltage +5 V / +24 V DC backplane outputs. This barrier restricts high-voltage surges, common-mode noise, and transient spikes from leaking into the delicate communication module logic circuits.
Q: How does the module handle short-term input power degradation or drops?
A: The internal storage capacitor matrix provides an input voltage interruption holdup time of up to 50 ms. This threshold ensures the RTU560 continues standard processing operations during local switching anomalies or battery bank transient sags without triggering a system reset.
