1.Main Functions

1. Multi‑channel analog voltage signal sampling: Collects multi‑channel analog voltage signals from external sensors, transducers and measurement points, completes high‑precision A/D conversion from analog signal to digital data.
2. On‑board DSP real‑time signal processing: Built‑in Digital Signal Processor (DSP) performs local hardware computing. Supports real‑time filtering, FFT spectrum analysis, effective‑value calculation and peak‑value extraction on the card, avoids massive raw‑data transmission to upper computer and lowers PC computing burden.More products: www.plcva.com

ET4‑VOL1.5 DSP‑Embedded Multi‑Channel Voltage Data Acquisition Card

ET4‑VOL1.5 DSP‑Embedded Multi‑Channel Voltage Data Acquisition Card

1. Programmable input range: Configurable voltage measurement range for different industrial sensors, adapts to output signals from vibration, pressure, displacement and torque transducers.
2. Synchronous sampling capability: Supports multi‑channel simultaneous acquisition, guarantees time consistency of multi‑group measurement data for correlation analysis.
3. Galvanic isolation protection: Isolation between field signal side and PC bus side, suppresses common‑mode interference and surge noise in industrial environment, protects industrial host equipment.
4. On‑board buffer memory: Equipped with local high‑speed buffer RAM for temporary data storage; supports continuous streaming acquisition without data loss under high sampling rate.
5. Standard bus communication: Transmits processed measurement results and raw sampling data to industrial PC via PCI/PCI‑E bus; provides driver & SDK for secondary development.
6. Self‑diagnosis function: Detects hardware overrange, overvoltage and communication abnormal status; returns fault status code for quick troubleshooting.
