Application Scenarios:
- Ethylene plant burner management systems
- Offshore platforms (corrosive environments)
- Wastewater treatment emergency pump controls
- Chemical processing plants
Performance Parameters:
- Input Range: 85-264 VAC
- Output: 24 VDC
- Redundancy: 1:1 Hot-standby
Material Composition:
- Industrial-grade electronic components
- Metal housing for heat dissipation
- Conformal coated PCB
Structural Features: The module features a front panel with status LEDs and a connector for the backplane. It is designed to be inserted into specific power slots (P1/P2).
Working Principle: The module converts AC mains power to stable 24 VDC for the control system. In a redundant setup, if one module fails, the other takes over the load instantly without interrupting power to the system.
Installation Requirements:
- Install in slot P1 (single) or P1 and P2 (redundant).
- Use identical modules for redundancy.
- Ensure proper grounding.
Usage Notes:
- Do not use as a general-purpose power supply; it is designed for Yokogawa systems.
- Verify the suffix code for environmental requirements (e.g., -E for explosion-proof).
- Check status LEDs for fault diagnosis.
