Description
The Yokogawa PW404 S1 Power Supply Module is a 24 V DC input power supply module specifically for the Yokogawa CENTUM CS3000 distributed control system. PW404 serves as the primary power conversion unit that supplies stable DC power to Field Control Units (FCU), FIO Node Units, and Optical ESB Bus Repeater Units within the control system architecture.
PW404 accepts a 24 V DC input power supply voltage with an operating range of 24 V DC ± 10%. The maximum power consumption of PW404 is 5.5 A, providing adequate power capacity to support the connected processor modules, I/O modules, and communication interfaces within the CENTUM CS3000 system.
For high-availability applications, PW404 supports dual-redundant power supply configuration. Two identical PW404 modules can be installed in the designated power supply slots (P1 and P2) to create a redundant power architecture. In a dual-redundant configuration of PW404, if one module fails, the second module automatically maintains power to the system without interruption. For single power supply configurations, PW404 must be installed in slot P1. This redundancy capability of PW404 is essential for critical process control applications where power continuity is paramount.

Features:
- 24 V DC Input Power Supply
- Dual-Redundant Configuration Capability
- Field Control Unit and Node Unit Compatibility
- Maximum Power Consumption of 5.5 A
The module provides regulated outputs including 5.1 V DC at 7.8 A for internal logic circuits and 24 V DC at 1.7 A for auxiliary power distribution. The maximum input current consumption is 5.5 A at nominal 24 V DC input. The PW404 uses exclusive proprietary connectors and is not a generic power supply — it is specifically designed for integration with Yokogawa control system hardware.
The PW404 S1 Yokogawa Power Supply Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

PW404 is compatible with various Yokogawa system components including Field Control Units (AFV30D, AFV30S, A2FV50D, A2FV50S, A2FV70D, A2FV70S), FIO Node Units (ANB10D, ANB10S, ANB11D, ANB11S), and Optical ESB Bus Repeater Units (ANT10U). The input/output interface of PW404 uses an exclusive connector designed for reliable power distribution within the system chassis. The power supply terminals of PW404 use M4 screw connections for secure field wiring.
- Oil & Gas Refineries: Powers upstream extraction, pipeline monitoring, and downstream processing controls
- Petrochemical/Chemical: Supports critical operations with safe ProSafe shutdown logic
- Power Generation: Controls/monitors boilers, turbines, and electrical distribution
- Water/Wastewater: Provides fault-tolerant power for pumping stations and purification
- Pharmaceutical: Powers data acquisition for regulatory compliance and data integrity

Input Power: The PW404 is rated for 220 V AC. Connect the power cables to the designated terminal block using M4 screws or a pressure clamp terminal as specified by your rack configuration.
Earth/Ground Wiring: Ground the power supply terminal immediately following the hardware instructions. This is a mandatory safety measure against electric shock and helps minimize electrical noise in the system.
Technical notes
PW404 is available with multiple suffix code options to suit different application requirements. The standard type (suffix code -5) provides basic power supply functionality with no explosion protection. The explosion protection type (suffix code -E) is available for hazardous area applications. The basic type (suffix code 0) provides standard operating temperature range, while the ISA Standard G3 option (suffix code 1) extends the operating temperature range to -20°C to +70°C for harsh industrial environments
FAQs
-
What exactly is the Yokogawa PW404 S1?
+It is a dedicated Power Supply Module designed specifically for Yokogawa's Distributed Control Systems (DCS) to ensure stable, clean, and redundant power delivery across the rack/bus units in industrial control environments. -
What are the primary specifications of the Yokogawa PW404 module?
+While closely related to sister models like the 100-120V AC input PW401 and the 220-240V AC input variants, the PW404 is custom-configured to drive internal DCS infrastructure. It utilizes an industrial, high-current design featuring low ripple noise and built-in protections against overvoltage, overcurrent, and short circuits. -
What does the S1 suffix designate?
+The "S1" designates Style 1 (Series 1), identifying the specific physical engineering revision and internal circuit design used during its original manufacturing run. Hardware revisions (such as Style 1 vs. Style 2) often dictate mounting alignments, component footprint depths, or minute shifts in optimal heat dissipation layout. -
Can I hot-swap a PW404 S1 module while the DCS system is powered?
+No, hot-swapping legacy Yokogawa power supply modules without proper system bypass documentation risks serious damage. Whenever changing modular hardware under active plant power, ensure you do not touch any inner chassis components due to the severe risk of fatal electric shock. Check your specific architecture manual to see if redundant dual-power configurations are actively supporting your rack before pulling any module
