Technical Specifications Multi‑channel signal input‑output terminals, internal bus connection interface. Auxiliary power 24 V DC, typical power consumption 3.6 W. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Conformal coated printed circuit board.
Functional Features Performs noise filtering for incoming control signals. Suppresses high‑frequency electromagnetic interference inside converter cabinet. Delivers filtered clean signals to subsequent control boards. On‑board LED indicates power supply operating status. Built‑in hardware self‑diagnosis detects internal circuit abnormality.
Application Scenarios Signal filter spare part for ABB industrial variable‑frequency drive. Applied for drive cabinet internal hardware maintenance and replacement.
Performance Parameters Efficient high‑frequency interference suppression. Low signal attenuation during filtering process. Stable long‑time continuous working performance.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Filter circuit assemblies, surge suppression components. Conformal protective coating. Signal wiring terminals and internal plug‑in connectors.
Structural Characteristics Cabinet fixed‑mount circuit board. Equipped with external signal terminals and internal connectors. Reserved mechanical fixing holes. Weight approximately 0.37 kilogram.
Working Principle Incoming control signals pass through multi‑stage filter circuit on the board. High‑frequency interference noise is absorbed and suppressed. Clean signals are transmitted to downstream control hardware. Diagnosis circuit monitors internal circuit operating state continuously.
Installation Requirements Cut off converter main power and auxiliary power before replacement. Secure AFIN‑01C 64693808 to specified mounting position. Complete signal input‑output wiring and internal connector connection. Restore power supply and verify control signal stability.
Usage Notes Use shielded cables for external control signal wiring. Keep board away from high‑heat power components. Do not scratch conformal coating. Verify drive no‑load running status after replacement.
