Description
Foxboro CM902WX
Technical Specifications
- Model Number: CM902WX
- Input Voltage: Selectable 100/120/220/240 VAC
- Output Voltage: 24 VDC
- Product Series: CM900 Series I/A Series Industrial Power
Functional Features
- Wide Input Range: Accommodates global AC power standards without manual transformer swapping.
- Status Monitoring: Features two front-panel LED status indicators for quick visual diagnostics of power health.
- Thermal Management: Equipped with a rear-mounted heat sink to efficiently dissipate heat during continuous operation.
Application Scenarios
Essential for all Foxboro I/A Series DCS installations in manufacturing plants, refineries, and automated processing facilities requiring uninterrupted system power.
Performance Parameters
- Efficiency: High-efficiency power conversion minimizing energy loss and heat generation.
- Stability: Tight voltage regulation to ensure sensitive control modules receive clean, ripple-free DC power.
Material Composition
Constructed with industrial-grade capacitors, transformers, and solid-state components housed in a durable metal chassis for EMI shielding and physical protection.
Structural Characteristics
- Compact Form Factor: Designed to maximize panel space while delivering robust power.
- Thermal Design: Rear heat sink ensures that heat is directed away from adjacent sensitive electronic modules.
Working Principle
The module receives raw AC mains power, steps it down through an internal transformer, rectifies it to DC, and regulates it to a precise 24 VDC output using advanced switching power supply topology.
Installation Requirements
Mount in a well-ventilated area to allow adequate airflow over the rear heat sink. Ensure input AC wiring is properly fused and grounded according to local electrical codes.
Usage Precautions
Always select the correct input voltage jumper setting before applying power. Never short-circuit the 24 VDC output terminals, as this can trigger internal protection circuits or cause permanent damage.
