Features:

  • Converts 100-120 V AC, 50/60 Hz input power into 24 V DC output for compatible industrial control system hardware.
  • Supports dual-redundant operation using two power supply modules, helping maintain power availability in continuous industrial processes.
  • Uses a 19-inch rack-mount structure secured by four M5 screws for organized and stable system installation.
In industrial control environments, dependable power distribution plays an important role in keeping control and communication hardware operating consistently. Yokogawa PW441-11 S2 provides the DC power required by compatible system equipment from a standard 100-120 V AC source. The 24 V DC output supports integration into rack-based control architectures. A 50/60 Hz input frequency range accommodates common industrial AC supplies. The module is therefore suited to installations where centralized and reliable system power is required.

System availability is strengthened through the redundant architecture associated with Yokogawa PW441-11 S2. Two power supply modules are installed for dual-redundant operation, while two VI461 communication modules provide corresponding communication redundancy. A single configuration is not available under the specified hardware arrangement. Such architecture is valuable in process automation environments where interruption of power or communication can affect system continuity.

Physical integration of Yokogawa PW441-11 S2 follows a 19-inch rack-mount format using four M5 mounting screws. The arrangement allows power and communication hardware to be installed together in a structured equipment rack. With 80 VA power consumption and 24 V DC output, the module provides a practical power conversion stage between the incoming AC source and system hardware. The combination of rack installation and redundant configuration makes the module appropriate for control systems that emphasize organized hardware deployment and continuous operation.

The PW441-11 S2 Yokogawa Power Supply Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

General

  • Manufacturer Yokogawa
  • Model PW441-11 S2
  • Condition New Original ready stock
  • Product Family PW481-50 S2,PW482-50 S2,PW482-10 S2
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Rack Preparation: Ensure two adjacent slots are reserved in a standard 19-inch rack to accommodate redundant power supply installation.
  • Polarity Verification: Before connecting to a single-phase 100-120V AC line, use a multimeter to verify the live and neutral wire connections.
  • Solid Grounding: Use a grounding wire of at least 2.0 mm² to directly connect the module's M4 screw terminals to the system protective ground.
  • Hot-Swapping: When replacing a faulty module in redundant mode, ensure the other power supply is functioning correctly before hot-swapping.
  • Status Indicator Judgment: Observe the panel LED indicators. A constantly lit GREEN light indicates normal output, while a red light indicates overload.
  • Ripple Voltage Measurement: Periodically use an oscilloscope to measure the system's 24V DC bus to ensure the output ripple is less than 100 mVp-p.
  • Overheating Power Drop: Check the status of the cabinet exhaust fan to prevent overheating protection activation of the module due to ambient temperatures exceeding 60°C.
  • Log Code Verification: Check the HIS diagnostic screen for power failure alarm codes via the CENTUM VP operator station.
  • Offshore Drilling Platforms: Utilize G3-grade anti-corrosion coating to withstand the extreme marine instrument panel environment of high salt spray and high humidity.
  • Refinery Hydrogenation Units: Provide uninterrupted power to safety control units in high-concentration hydrogen sulfide gas environments over long periods.
  • Large Thermal Power Plants: Provide highly reliable redundant dual power supply to the main controller rack of the DDC distributed control system.
  • Coal Chemical Control Rooms: Handle grid voltage fluctuations within the 90-122V AC range caused by the start-up and shutdown of large on-site motors.
Description
Yokogawa PW441-11 S2 serves as an AC power supply module for industrial control system installations where stable DC power is required for system hardware. Operating from a 100-120 V AC source at 50/60 Hz, the module converts incoming AC power into a 24 V DC output. Power consumption is rated at 80 VA, providing a defined power interface for compatible control and communication equipment.

For installations requiring continuous system operation, Yokogawa PW441-11 S2 is used in a dual-redundant arrangement. The hardware configuration specifies two PW441, PW442, or PW444 power supply modules rather than a single-module configuration. Two VI461 communication modules are also installed for dual redundancy, creating a hardware architecture intended to reduce dependence on a single power supply or communication module.

Yokogawa PW441-11 S2 is installed in a 19-inch rack and secured with four M5 screws. Rack mounting provides an organized installation method for control cabinets and system racks where multiple modules must operate together. Combined with the required redundant hardware arrangement, the module is suitable for industrial control applications where dependable system power and structured hardware integration are important.
