Technical Specifications Multi‑channel analog signal input interfaces, digital data output interface, auxiliary DC control power supply. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Conformal coated circuit board.
Functional Features Receives analog voltage and current sampling signals from power unit. Completes signal filtering, amplitude adjustment and noise suppression. Executes high‑precision analog‑digital conversion. Transmits digital sampling data to main control board. Detects sampling channel over‑range and signal loss fault condition.
Application Scenarios Spare analog sampling board for ABB excitation and high‑power converter systems. Applied in power generation and industrial drive equipment maintenance projects.
Performance Parameters High‑precision multi‑channel analog‑digital conversion performance. Good anti‑interference capability for industrial analog sampling signals. Reliable channel fault detection function.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Analog signal conditioning circuit, analog‑digital conversion chip, data transmission peripheral assemblies. Multi‑pin plug‑in connectors and metal screw mounting hardware. Conformal protective coating layer.
Structural Characteristics Rectangular circuit‑board structure. Power‑unit‑side analog input connectors and main‑control‑side data output connectors are distributed on different edges. Reserved screw mounting holes for cabinet bracket fixation. Analog sampling area and digital transmission area maintain clear layout separation.
Working Principle XVC517AE02 3BHB004744R0002 obtains auxiliary DC control power supply. Analog sampling signals from power unit enter input channels, pass through filtering and amplitude conditioning circuit. Analog‑digital conversion chip converts analog quantity into digital value, and sampling data is transmitted to main control board through data interface.
Installation Requirements Fasten board to cabinet mounting bracket with screws. Fully insert and lock each plug‑in connector. Restore auxiliary power supply, verify sampling value accuracy under static simulation condition.
Usage Notes Sampling signal wiring polarity must be correct. Anti‑static operation is mandatory. Hot‑plug under powered condition is prohibited. Keep conformal coating layer intact.
