Technical Specifications Multi‑channel analog signal input interfaces. Auxiliary power supplied by host equipment power unit. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Built‑in signal filtering and surge suppression circuit.
Functional Features Receives raw measuring signals from field sensors and transducers. Completes signal filtering, amplitude adjustment and level conversion. Outputs conditioned measuring signals to main control board. Collects partial hardware status signals and feeds back to upper system. Reserved test points support maintenance signal measurement.
Application Scenarios Spare signal processing board for ABB power‑industry automation equipment. Applied in generator set and power‑control cabinet maintenance projects.
Performance Parameters Low‑noise analog signal processing performance. Stable long‑term signal sampling accuracy. Reliable signal anti‑interference capability.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Analog filtering and conditioning assemblies, multi‑pin connectors and metal fixing hardware. Circuit surface conformal anti‑humidity coating.
Structural Characteristics Rectangular flat circuit board. Multiple signal input‑output connectors distributed on board edges. Screw mounting holes for cabinet fastening.
Working Principle Raw analog signals from field sensors enter the board through connectors. After filtering and amplitude adjustment processing, high‑quality measuring signals are transmitted to main control board for further calculation. Status feedback signals are uploaded via dedicated signal paths.
Installation Requirements Completely cut off host equipment power supply before replacement. Take anti‑static protection measures. Fasten HIEE300698R0001 to designated cabinet position. Insert all multi‑pin connectors in alignment. Restore equipment power supply, verify measuring signal sampling precision of related channels.
Usage Notes Avoid pin bending during connector plug‑in. Hot‑plug under powered state is prohibited. Compare measuring value with actual field signal after installation.
