ABB PFEA111-20 3BSE028140R0020 Compact DIN-Rail Tension Amplifier Module

PFEA111-20 with part number 3BSE028140R0020 is ABB’s cost-effective compact tension measuring amplifier under the PFEA tension electronics series, designed to match Pressductor load cells for web production tension monitoring and closed-loop control. It accepts dual load cell input signals, processes and outputs standardized 4–20mA / 0–10V analog tension signals, and features a built-in LCD screen to separately display channel A, channel B, sum (A+B) and differential (A-B) tension values for on-site visual checking.

This IP20 DIN rail mounted unit adopts industrial anti-interference circuit design with adjustable signal filtering to suppress vibration and electromagnetic noise from printing, papermaking and film slitting lines. Equipped with four physical operation keys for parameter calibration, zero reset and range setting, it requires no extra handheld calibrator for routine debugging. Widely used as maintenance spare parts for winding/unwinding tension control racks in continuous material processing production lines.

Core Functions

• Collect weak strain signals from two tension load cells, amplify and filter raw signals to eliminate mechanical vibration and electrical interference noise.
• Calculate real-time tension sum and differential values, output unified analog control signals to inverters and DCS systems for closed-loop tension regulation.
• Onboard LCD real-time display of single-channel tension, total tension and deviation, supporting one-key zero calibration and measuring range adjustment via front panel keys.
• Built-in multi-stage signal filtering with adjustable filter time constant to adapt high-speed slitting, coating and printing production lines with dynamic tension fluctuation.
• Internal hardware self-diagnosis detects load cell open-circuit, short-circuit and power supply anomalies, triggering display fault prompts to shorten on-site troubleshooting time.
• Compact slim DIN rail structure saves cabinet space, unified terminal definition allows direct ｄｒｏｐ-in replacement without reworking wiring during equipment overhaul.
