DSTA155 57120001-KD ABB Distributed system terminal adapter System 800xA
DSTA155 57120001-KD ABB Distributed system terminal adapter System 800xA
ABB DSTA155 is a key Distributed System Terminal Adapter in the System 800xA distributed control system. It is mainly used for seamlessly integrating traditional 4-20mA, HART or switch field devices into modern AC 800M control architectures. This module can be installed in remote I/O stations or local cabinets, serving as an intelligent bridge between field instruments and controllers. It supports signal conditioning, diagnostic upload, and parameter configuration, significantly enhancing system integration efficiency and operation and maintenance transparency.
