Description
Woodward 8237-1367
Technical Specifications
- Part Number: 8237-1367
- Input Voltage: 24 VDC or 120 VAC
- Output Voltage: 24 VDC regulated
- Redundancy: Hot-swappable, parallel operation
Functional Features
- Hot-Swap Capability: Allows replacement without powering down the safety system.
- Power Monitoring: Reports input voltage, output current, and internal temperature.
- Battery Backup: Supports external battery backup for extended outage ride-through.
Application Scenarios
Essential for all ProTech-SX installations to ensure uninterrupted safety system operation during plant power disturbances.
Performance Parameters
- Ripple: <50 mV peak-to-peak.
- Efficiency: >90%.
Material Composition
Industrial-grade switching power supply components with high-temperature capacitors.
Structural Characteristics
- LED Indicators: Power OK, load current, and fault status.
- Thermal Management: Convection-cooled with no moving parts.
Working Principle
Converts AC or DC input to regulated 24 VDC output. Multiple modules operate in parallel, sharing load current equally. If one module fails, the remaining modules seamlessly take the full load.
Installation Requirements
- Ventilation: Maintain minimum clearance for airflow.
- Battery Connection: Connect backup batteries with correct polarity.
Usage Precautions
- Battery Maintenance: Test backup batteries quarterly per manufacturer recommendations.
- Load Balance: Ensure even load distribution across parallel modules.
