- Output Current: Maximum continuous output current of 10 A.
- Conversion Efficiency: High-efficiency topology reaching up to 92%.
- Operating Temperature: -25°C to +70°C.
Functional Features:
- Bus Termination: Minimizes signal reflections on the PROFIBUS DP network to ensure stable communication.
- Power Conversion: Provides isolated, regulated auxiliary voltage for sensors, relays, or other automation equipment.
- Protection: Comprehensive over-voltage, over-current, and short-circuit protection.
- Continuous Power: Supports up to 15 W continuous output for auxiliary loads.
Application Scenarios:
- Terminating and powering remote PROFIBUS DP network segments.
- Supplying stable power to field instruments in harsh industrial environments.
- Auxiliary power distribution in manufacturing, oil and gas, and water treatment facilities.
Material Composition & Structural Characteristics:
- Mounting: Supports standard DIN rail mounting or direct PCB mounting.
- Dimensions: Compact footprint (approximately 10 x 10 x 5 cm).
- Thermal Management: Designed for efficient heat dissipation in enclosed panels.
Working Principle:
The module connects to the end of a PROFIBUS DP cable to terminate the bus electrically. Simultaneously, its internal switch-mode power supply converts the incoming DC voltage to a precise, regulated output voltage, providing clean power to connected field devices.
Installation Requirements:
- Install strictly at the physical ends of the PROFIBUS DP network.
- Ensure adequate ventilation if operating near the upper temperature limit.
- Connect the DC input with correct polarity.
Usage Precautions:
- Do not exceed the 10 A maximum output current.
- Verify the output voltage matches the connected auxiliary equipment requirements before powering up.
