Product Introduction

The ABB DSAX452, part number 5712289-A, is an analog I/O basic unit belonging to ABB S400 remote I/O system for Advant Master and Advant OCS distributed control systems. It integrates analog input and analog output channels, collecting analog measurement signals from field transmitters and outputting control signals to field actuators. It communicates with the main DCS controller via MasterFieldbus SDB fieldbus. With industrial housing design and reliable EMC protection, the module can operate stably under harsh industrial environments with temperature fluctuation, dust, vibration and electromagnetic interference. Widely used in power generation, pulp & paper, petrochemical and metallurgical industries. It is an important spare part for legacy Advant DCS cabinet maintenance, analog I/O unit replacement and old automation system renovation.

Brand: ABB Model: DSAX452 Part No: 5712289-A Product Type: Analog I/O Basic Unit Applicable System: ABB Advant Master, Advant OCS, S400 Remote I/O System Communication Bus: MasterFieldbus SDB AI:14 channels, 12-bit resolution, configurable for current or voltage, differential or single-ended AO:6 channels, 10-bit resolution, unipolar current and voltage signal output The ABB DSAX452 5712289-A is a remote I/O basic unit installed in the field I/O cabinet. It acquires analog process signals such as temperature, pressure and flow from field sensors, converts them into digital data and transmits to the DCS main controller through MasterFieldbus SDB. Meanwhile, it receives control commands from the controller and converts them into analog output signals to regulate valves and other field control devices. It supports self-test, power loss monitoring and communication diagnosis. Every unit undergoes full functional testing and aging screening before shipment to guarantee reliable 24/7 continuous operation. Built-in signal filtering and surge suppression circuits reduce field electrical noise and protect internal circuits from transient voltage spikes. LED indicators on the front panel display operation status, transducer power supply and A/D converter status, helping maintenance staff quickly locate signal wiring or module faults and shorten plant downtime. Typical application scenarios include power plant process parameter monitoring, paper mill analog signal acquisition, chemical continuous process control and metallurgy process measurement. When the original analog I/O basic unit fails, DSAX452 5712289-A can be directly replaced to restore analog signal acquisition and output function of the whole S400 remote I/O system. This module complies with IEC industrial safety and EMC standards with IP20 protection rating. Robust housing and durable electronic components support long-term stable operation. Whether you prepare spare inventory for equipment overhaul or purchase components for legacy DCS retrofit projects, the ABB DSAX452 analog I/O basic unit provides dependable analog signal acquisition and control output for your Advant Master automation system.
