Product Description

PFEA112-65 is an integrated tension control unit designed by ABB for harsh industrial environments. It integrates dual-channel sensor input, DSP signal processing, PID control and industrial communication. It can be directly installed on the equipment body or in the workshop site, dustproof and waterproof, and does not require an additional control cabinet. Model Interpretation
