ABB PFEA111‑20 Tension Electronics Module

Technical Specifications Model: PFEA111‑20 3BSE028140R0020 Mounting Mode: Standard DIN‑rail installation inside control cabinet Power Supply: DC 24 V, 18‑36 V allowable range Power Consumption: 7.5 W Load Cell Excitation: 0.5 A rms, 330 Hz Display: 2×16‑character LCD display Analog Output: 0‑10 V or 4‑20 mA configurable Operating Temperature: 0 °C to +55 °C Storage Temperature: ‑25 °C to +70 °C Relative Humidity: 5‑95 %, non‑condensing Protection Class: IP20 Certifications: CE

Functional Features Calculates tension sum value, difference value and individual sensor measured value. Supports local parameter setting via front‑panel physical keypad. Provides real‑time local tension value reading on LCD screen. Built‑in digital signal filtering function suppresses mechanical vibration interference. Implements sensor breakage and fault detection function. Analog output gain and offset parameters support on‑site scaling configuration.

Application Scenarios Spare‑part replacement of PFEA111‑20 tension module inside paper‑making, printing and converting machine control cabinet. Web tension monitoring and analog signal output for textile, film and flexible packaging production lines. Tension measurement retrofit project for existing web processing equipment without field‑bus communication demand. Hardware maintenance and component renewal for legacy ABB tension control system.

Installation Requirements Cut off related cabinet power supply before module replacement work. Snap module firmly onto standard DIN‑rail inside IP20 control cabinet. Complete wiring for load‑cell shielded cable, DC24V power supply and analog output signal. Carry out protective earthing according to cabinet grounding specification. Reserve sufficient surrounding space for module heat dissipation. Ambient operating temperature shall keep within 0 °C‑+55 °C without condensation. Complete sensor calibration procedure and verify analog output signal accuracy after power‑on.

Usage Notes Strictly implement lock‑out‑tag‑out safety procedure before cabinet wiring operation. Wear anti‑static wrist strap during module disassembly and replacement.
