HP-DY is a 24-bit high-speed, multi-channel DAQ and analysis system with synchronous parallel sampling up to 256 kHz, mixed inputs (AC/DC/IEPE/strain), and a 19-inch rackmount form factor for test benches and integrated measurement racks.
| Hybrid inputs per channel | Configure each channel for DC, AC, IEPE, or strain-gauge input types—true universal input without extra auxiliary modules. |
|---|---|
| Per-channel hardware auto-balance | Independent 16-bit D/A per channel enables full-range auto-balance (zero) without losing measurement range; supports manual zero point setting based on test needs. |
| High-speed synchronized sampling | High-stability conditioning + 24-bit high-performance ADC. All channels support synchronous parallel sampling, display, and storage, up to 256 kHz maximum. |
| High accuracy & strong anti-interference | Built-in independent 120 Ω bridge resistor per channel, stable amplification/conditioning, and high-performance ADC for 0.2% test accuracy. |
| Excitation & IEPE power built-in | Per-channel 0–10 V / 400 mA excitation (software configurable, 0.1% accuracy), plus rear excitation supplies +24 V / +12 V, and IEPE 4 mA constant-current source with conditioning. |
HP-DY is engineered for dynamic testing where you need stable conditioning, synchronized acquisition, and scalable channel counts. It supports common dynamic and industrial signals—strain, vibration/acceleration (IEPE), voltage/current loops, temperature, pressure, and displacement—while offering adjustable excitation supplies and fast hardware auto-balance for efficient setup.
