Key Features and Benefits
Dual-Output Voltage for Multi-Component Power Supply
The YOKOGAWA PW441-10 provides two isolated DC outputs (+5.1V/7.8A and +24V/4A), eliminating the need for multiple single-output power supplies. The +5.1V rail powers sensitive PLC core components (e.g., microprocessors, memory modules) with low ripple (<50mV), ensuring stable data processing and program execution. The +24V rail supplies field devices such as sensors, actuators, and communication modules—critical for industrial automation workflows. For example, in a manufacturing assembly line, the module can simultaneously power a Yokogawa STARDOM FCN PLC (via 5.1V) and its connected proximity sensors (via 24V), simplifying wiring and reducing points of failure.
Hot-Swap Design for Zero-Downtime Maintenance
Equipped with hot-swap functionality, the YOKOGAWA PW441-10 allows module replacement during system operation—eliminating the need for costly shutdowns in continuous-process industries (e.g., oil refineries, chemical plants). This feature is supported by Yokogawa’s redundant power architecture: when paired with a backup PW441-10 module, the system automatically switches to the standby unit during maintenance, ensuring uninterrupted power supply to critical loads. LED status indicators (SYS for 5V, FLD for 24V) provide real-time visibility of output health, enabling technicians to quickly identify and resolve issues without disrupting operations.
Robust Protection Mechanisms for Equipment Safety
The module integrates three layers of protection to safeguard connected devices:
- Over-Voltage Protection (OVP): Triggers at 110% of rated output to prevent damage to voltage-sensitive components (e.g., PLC I/O cards).
- Over-Current Protection (OCP): Limits current to 120% of rated value to avoid overheating in short-circuit scenarios.
- Short-Circuit Protection (SCP): Instantly cuts off power to faulty circuits, preventing fire hazards and component burnout.
These mechanisms comply with global safety standards (CSA, FM, ATEX), making the YOKOGAWA PW441-10 suitable for hazardous environments such as offshore platforms and chemical storage facilities.
High Efficiency and Temperature Resilience
With an efficiency rating of ≥85% at 50%-100% load, the
YOKOGAWA PW441-10 minimizes energy loss and heat generation—reducing cooling requirements in control cabinets. Its operating temperature range (0°C to 55°C) and storage tolerance (-40°C to 85°C) ensure reliable performance in extreme industrial environments, from freezing warehouses to high-temperature manufacturing plants. The flame-retardant ABS housing (UL94 V-0) further enhances safety by resisting ignition and preventing flame spread in case of electrical faults.
