The PFVO142 is an ABB signal matching unit specifically designed for tension/rol
The PFVO142 is an ABB signal matching unit specifically designed for tension/rolling force measurement systems. Its core function is to provide excitation, signal conditioning, and impedance matching for tension/pressure sensors, enabling high-precision force signal acquisition and transmission. It is widely used in continuous production scenarios such as steel, papermaking, and metallurgy.
I. Model and Order Number Explanation
PFVO142: Series model, matching unit
3BSE023732R1: Standard order number (mainstream in-stock model)
3BSE223732R0001: Derivative/customized model in the same series, with functions basically the same as 3BSE023732R1
II. Core Functions
Sensor Excitation Power Supply: Provides stable excitation (rated 25A, 1638Hz) for tension/pressure sensors such as PFVL141V, PFVL141C, and PFVL141R.
Signal Conditioning and Matching: Receives weak strain signals from the sensor, amplifies, filters, and performs impedance matching before outputting a standard signal.
Transmitter Output: Converts physical force values into 4–20 mA or digital signals for connection to PLC/DCS systems.
Diagnosis and Protection: Built-in overcurrent, overvoltage, and open-circuit detection to ensure sensor and module safety.
III. Key Technical Parameters
Rated Excitation: 25 A / 1638 Hz (compatible with high-current tension sensors)
Power Supply: 24 V DC (typical), compatible with wide voltage range
Output Signal: 4–20 mA analog/digital bus (Modbus, Profibus DP, etc.)
Protection: IP20 (industrial rack mounting), optional IP65 reinforced enclosure
Operating Temperature: -40°C to +70°C, suitable for harsh industrial environments
Dimensions/Weight: Approx. 263×58×28 mm; Weight 4.3–7 kg (slight variations depending on the version)
IV. System Compatibility and Applications
Compatible Sensors: PFVL141V, PFVL141C, PFVL141R, PFTL101A, etc. tension/pressure head sensors
Compatible Units: PFVI401 excitation unit, PFXA401 control unit, PFSK152 signal integration board
Typical Applications:
Steel rolling mill: closed-loop control of rolling force/tension to ensure strip thickness and flatness
Paper making/ Printing: Roll tension control to prevent paper breaks and wrinkles. Metallurgy/Cable: Tension monitoring and adjustment for continuous production lines.
