The ABB 3BSE021180R1 PFSK164 is a high‑performance tension measurement processing board designed for ABB Advant Master automation systems. It collects weak analog signals from load‑cell tension sensors, performs signal amplification, conditioning and digital conversion to realize closed‑loop tension control for production lines. Equipped with multi‑channel analog and digital I/O as well as Ethernet and serial communication interfaces, it delivers powerful local computing capacity. Galvanic isolation and anti‑interference circuits are integrated to adapt to harsh paper‑making and metallurgical workshop environments. Standard euro‑card rack‑mount design supports quick on‑site replacement. Front‑panel LED indicators facilitate fast fault diagnosis. As a critical spare part for legacy tension‑control systems, each unit passes comprehensive testing before shipment for overhaul and maintenance work.
