ABB PFEA112‑20 Tension Electronics Module

Technical Specifications Model: PFEA112‑20 3BSE050091R20 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 Communication Interface: PROFIBUS‑DP 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 membrane keypad. Real‑time tension value local display on LCD screen. Built‑in adjustable digital signal filtering function. Load‑cell breakage and fault‑status detection function. Analog output scaling and offset parameter configurable. PROFIBUS‑DP bus realizes tension data upload and remote parameter access.

Application Scenarios Spare‑part replacement for PFEA112‑20 tension module inside industrial control cabinet. Web tension measurement project requiring PROFIBUS‑DP digital communication for paper‑making, packaging and textile production line. Cabinet‑installed tension control system mixed analog‑digital signal transmission application. Hardware renewal and maintenance for legacy ABB PROFIBUS‑DP tension measuring system.

Installation Requirements Cut off cabinet total 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, analog signal and PROFIBUS‑DP bus cable. Set correct PROFIBUS‑DP station address before power‑on. Complete protective earthing complying with cabinet grounding specification. Reserve heat‑dissipation clearance around module surface. Ambient operating temperature maintains within 0 °C‑+55 °C without condensation. Finish sensor calibration, verify analog output and PROFIBUS‑DP communication function after power‑on.

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