Application & Failure Scenarios
Application: Power supply hardware for legacy Yokogawa CENTUM CS 1000 field control equipment.
When replacement is considered: Power-related alarms, loss of power to associated control hardware, an unsuccessful system startup or a suspected power-unit failure during maintenance.
Downtime risk: A failed supply unit may prevent dependent control equipment from operating normally. Verify incoming power and the associated hardware before replacing the module.
Maintenance Considerations
| Replacement Planning | Legacy CENTUM CS installation guidance lists an eight-year recommended replacement cycle for the applicable PW402 power supply unit. This is a maintenance-planning reference, not a guarantee of remaining service life. |
|---|---|
| Electrical Safety | Isolate the power source and follow the equipment-specific maintenance procedure before handling or replacing the unit. Installation and grounding must meet the requirements of the installed system and local electrical standards. |
| Selection Check | Match the 220–240 V AC version to the installed hardware. Do not substitute a 100–120 V AC or 24 V DC version based on model-family similarity alone. |
