Product Overview

• Part No: SNAT609TAI
• Brand: ABB

• Category: Signal Interface Control BoardSNAT609TAI is a dedicated signal processing interface board designed for ABB ACS800 series inverters. It is responsible for collecting analog measurement signals and digital interlock signals inside the drive, transmitting processed data to the main control board, and distributing control signals to each functional unit. The board processes motor current, voltage feedback and external safety interlock signals, realizes signal filtering, conversion and isolation, and supports fault signal acquisition and feedback transmission. It is an indispensable signal conversion component to guarantee stable closed-loop operation of the frequency converter.
