Yokogawa PW482-10 Input Power Supply Module

High Reliability: Supports redundant configuration. The Field Control Node (FCN) autonomous controller, fieldbus modules, and control networks all feature redundancy. Hot-swapping is supported, ensuring processes do not interrupt even when damaged modules are replaced. The fault-tolerant design guarantees the continuity of critical processes.

Seamless Integration: Enables seamless connection with Yokogawa DCS and SIS systems. Using a single process network saves engineering design time, while integrated information display is clearer and more practical. Common control and network architecture standards reduce maintenance costs and optimize factory operations.

Long-life Design: The aluminum electrolytic capacitors inside the power module have a long replacement cycle under suitable ambient temperatures. For example, in environments below 40°C, the replacement cycle for the 220V AC specification is 8 years.

Input Voltage: Typically 220V AC.

Capacitor Replacement Cycle: The aluminum electrolytic capacitors have an 8-year replacement cycle in environments below 40°C.

Abnormal Output Voltage: May be caused by internal voltage regulation circuit failures or unstable input voltage. First, check if the input voltage is within the rated range. If the input is normal, it may indicate internal circuit issues, requiring professional inspection and, if necessary, module replacement.

Module Overheating: May result from poor ventilation in the installation environment or excessive load. Ensure the module is installed in a well-ventilated area without obstructions, and check if the connected load exceeds the module's rated capacity. If the load is too high, adjust the load or increase the number of power modules.

Power Indicator Not Lit: May be due to poor power cable connection, blown fuse, or damaged internal power circuit. First, check if the power cable is properly connected and the fuse is intact. If both are normal, it may indicate internal module faults, requiring professional repair or replacement.

The output voltage of the main module is lower than the rated value (e.g., ≤90% of the nominal voltage).

Internal overheating, short circuit, or component failure in the main module.

Abnormal input power supply to the main module (e.g., power outage, voltage fluctuation beyond the range).
