Product Details

The UFC721AE 3BHB002916R0001 is analog signal conditioning scaling card for ABB Bailey INFI90 and Symphony Plus DCS system.

This UFC721AE card works as analog front‑end signal processing unit for Harmony I/O rack. It converts various non‑standard field sensor signals into standardized signals applicable for DCS controller acquisition.

Signal range can be flexibly configured by on‑board DIP switches to adapt to different field transmitter and sensor types.

Each channel adopts galvanic isolation design, effectively suppresses common‑mode interference from industrial site and improves measuring accuracy and stability.

It filters noise interference mixed in field signals, ensures reliable and stable data transmission to main control processor.

Built‑in hardware self‑diagnosis function can detect signal over‑range and channel abnormality, and output corresponding alarm information.

Standard plug‑in structure supports convenient on‑site overhaul and replacement without modifying controller configuration.

Widely applied in thermal power, petrochemical and other large‑scale process industry DCS transformation and maintenance projects.

It is important spare hardware for DCS system overhaul, analog signal loop debugging and defective UFC721AE card replacement.
