Technical Introduction of XPZ-02 Frequency-to-Current Converter
The XPZ-02 is a precision signal conditioning device that linearly converts pulse frequency inputs into standardized 4～20mA current signals. Its core architecture integrates an isolation-enhanced conversion IC with a MOSFET-based V/I transformation circuit, achieving 0.2% linearity through rigorous component selection. The unit accepts sinusoidal or square wave inputs (0.2-20Vp-p) with 100KΩ impedance, delivering stable current output even under fluctuating loads. Typical industrial deployments involve rotational speed monitoring when paired with SZMB-5T magnetic sensors, particularly in thermal management systems for critical infrastructure. The compact design operates reliably within ambient temperatures of 0～70℃ without requiring auxiliary cooling.31215

Application Advantages
In practical applications, the XPZ-02 demonstrates notable advantages in system integration. The galvanic isolation between input/output channels prevents ground loop interference, while the wide 180-260VAC power supply tolerance accommodates unstable grid conditions. Its plug-and-play design simplifies maintenance procedures, with front-accessible test points facilitating troubleshooting. The converter s compatibility with both two-wire and three-wire sensor configurations enhances deployment flexibility across diverse industrial measurement scenarios.4711
