Pepperl Fuchs UPR-03-M 1.6 m Ultrasonic Sensor Cable Assembly

Pepperl+Fuchs UPR-03-M 1.6 m Ultrasonic Sensor Cable Assembly

 

 

The Pepperl+Fuchs UPR-03-M is not an ultrasonic sensor cable assembly. It is a Universal Power Rail (DIN rail bus system) used to distribute 24 VDC power and fault signals to Pepperl+Fuchs K-System signal conditioners and isolators in control cabinets.

Basic Information

• Part Number: UPR-03-M
• Brand: Pepperl+Fuchs
• Type: Universal Power Rail / DIN Rail Power Bus
• Function: Power distribution + system wiring simplification for K-System modules

Technical Specifications

• Length: 1.6 m (1600 mm standard rail)
• Mounting: 35 mm DIN rail
• Conductors: 3 internal conductors
• Rated Voltage: 24 VDC
• Rated Current: up to 4 A
• Operating Temperature: approx. -40°C to +70°C
• Structure:
  • 2 conductors: power supply
  • 1 conductor: fault / diagnostic line
• Installation: Snap-in K-System isolator mounting

Key Features

• Provides centralized power distribution for multiple isolator modules
• Eliminates individual wiring between each signal conditioner
• Integrated fault signaling bus for system diagnostics
• Reduces cabinet wiring complexity and installation time
• Supports modular expansion of K-System racks
• Industrial-grade design for continuous operation

System Role (Important)

The UPR-03-M is the backbone of Pepperl+Fuchs K-System cabinets:

Power supply → UPR-03-M rail → multiple KFD2 / KFA isolators → PLC/DCS system

It ensures:

• Stable 24V power distribution
• Simplified wiring architecture
• Centralized fault monitoring

Application Areas

• Oil & gas instrumentation systems
• Chemical and petrochemical plants
• Power generation control cabinets
• Hazardous area (Ex) signal systems
• PLC / DCS analog signal isolation systems
• Industrial automation panels

Advantages

• Greatly reduces wiring time in control cabinets
• Improves system reliability and organization
• Supports large numbers of isolator modules
• Built-in fault monitoring capability
• Industrial safety and stability design

Precautions

• Must be used only with compatible Pepperl+Fuchs K-System modules
• Do not exceed 4 A total rail current
• Proper grounding required for stable operation
• Correct end caps must be installed for safety
• Not a sensor or signal cable (no measurement function)
