Product Overview
The Yokogawa CR5-PAA series (such as the CR5-PA1A and CR5-PA2A) is a dedicated Power Supply Board used in the CENTUM CS 3000 Distributed Control System (DCS). Installed within the system nest, this module converts incoming AC or DC plant power into stable, regulated DC voltages required by the internal bus and connected I/O modules. It plays a vital role in maintaining a reliable electrical environment for sensitive control hardware. Supplied as 100% brand new, original factory equipment, the CR5-PAA ensures continuous and stable operation of the control station.

Engineering Advantages
Stable Voltage Regulation
The CR5-PA*A uses switching regulation to deliver consistent output voltages even under fluctuating input power conditions, helping prevent system instability, logic errors, and unexpected resets.
Redundant Power Architecture
In dual-redundant setups, two power boards share the load. If one fails, the other instantly takes over without interruption, ensuring continuous operation of the control system.
Integrated Diagnostic Monitoring
The module provides real-time status feedback to the DCS. Any abnormal condition triggers alarms, allowing operators to detect issues early and perform preventive maintenance.
Efficient Thermal Management
Optimized PCB layout and heat dissipation design reduce thermal stress on components, improving reliability and extending service life in continuous operation environments.
FAQs
What is the difference between CR5-PA1A and CR5-PA2A?
The primary difference is input voltage rating: CR5-PA1A is typically used for 100–120 V AC systems, while CR5-PA2A supports 220–240 V AC. Selection depends on your site power supply.
How can I identify a failing CR5-PA*A module?
Check the front-panel “READY” LED. If it is off or indicates a fault while input power is present, the module may have triggered protection or failed internally.
Can the CR5-PA*A be hot-swapped?
Yes, in a dual-redundant configuration. One module can be replaced while the other continues supplying power, avoiding system downtime.
Does the power board include battery backup?
No, the CR5-PA*A does not include a battery. System memory backup is handled separately by CPU modules using dedicated batteries.
