Product Description

The ABB PFEA111-65 (3BSE050090R65) is a high-precision dual-channel tension control amplifier module under the ABB Pressductor® series, professionally designed for industrial web tension closed-loop control systems. It serves as the core signal acquisition, amplification and PID regulation unit for winding and unwinding processes, perfectly matching ABB PFTL series tension sensors. The module integrates sensor signal processing, multi-mode tension calculation, analog output and industrial communication functions, delivering stable, high-precision tension balance control for flexible material continuous production lines.

Adopting industrial microprocessor control architecture, this module supports dual-channel independent signal acquisition with four selectable tension calculation modes, including single-channel monitoring and differential tension calculation. It features configurable 15ms–1500ms step response for adaptive dynamic speed adjustment, effectively suppressing tension jitter during high-speed operation. Equipped with standard 18–36VDC wide-voltage power input, 7.5W rated power consumption and built-in overvoltage, reverse connection and short-circuit protection, it ensures power supply safety. It provides 0/4–20mA analog output for actuator driving and RS485 Modbus RTU communication for upper system docking. With dual IP20/IP65 optional protection grades and wide temperature adaptability, it supports 24/7 long-term stable operation in complex automated production environments.
