Product Introduction

The ABB 086349-002 is a rack-mounted measurement control PCB board designed for ABB legacy distributed control systems. It undertakes analog signal acquisition, signal conditioning and data processing tasks, collecting field measurement signals and transmitting processed data to the rack CPU through backplane bus. Adopting standard Eurocard plug-in design and industrial PCB layout, it maintains stable signal sampling under harsh industrial conditions with temperature fluctuation, dust, vibration and strong electromagnetic interference. This model has been discontinued by the original manufacturer, mainly used for maintenance and replacement of old automation equipment. Widely applied in power generation, pulp & paper, petrochemical and metallurgical process industries. It is a critical spare part for legacy DCS cabinet maintenance and control board replacement.

Brand: ABB Part No: 086349-002 Product Type: Measurement Control PCB Board Applicable System: ABB Legacy DCS System Mounting Type: Standard Eurocard rack mount The ABB 086349-002 is a plug-in Eurocard circuit board installed inside the DCS control rack. It is responsible for conditioning and processing analog field signals, converting raw sensor signals into digital values that the controller can read. It communicates with the main processor via the rack backplane bus, uploading real-time measurement values and module diagnostic status. Every unit undergoes full functional testing and aging screening before shipment to ensure reliable 24/7 continuous operation. Built-in signal filtering and surge suppression circuits filter electrical noise from field wiring and protect the backplane bus from transient voltage spikes. Galvanic isolation separates field side and control side to avoid ground loop interference. LED indicators on the front panel display power status, signal activity and fault alarms, helping maintenance engineers quickly locate wiring or board faults and shorten plant downtime. Typical application scenarios include power plant process monitoring, paper mill analog signal collection, chemical continuous process measurement and metallurgy parameter acquisition. When the original measurement control board fails, 086349-002 can be directly replaced to restore analog signal processing function of the whole legacy DCS system. This module complies with IEC industrial safety and EMC standards with IP20 protection rating. Compact rack layout 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 086349-002 measurement control board provides dependable signal processing for your ABB automation system.
