Technical Specifications Supply: 24 V DC ±10%; input: LVDT 3-wire; output: 4–20 mA two-wire; stroke range: 0–50 mm; accuracy: ±0.25% FSO; operating temp: -40 °C to +85 °C; IP40.
Functional Features Precision position-to-analog conversion; zero and span adjustment; open circuit detection; reverse polarity protection; low temperature drift.
Application Scenarios Actuator position feedback, valve position indication, turbine gate position sensing, linear displacement monitoring.
Performance Parameters Accuracy: ±0.25% full scale; temperature drift: < 0.01% per °C; response time: < 5 ms.
Material Composition Industrial plastic housing; precision analog circuit; LVDT excitation stage; output driver.
Structural Characteristics DIN rail mount; front zero/span adjustment pots; rear terminal block.
Working Principle Excites the LVDT sensor, conditions the position feedback signal, and converts displacement to a proportional 4–20 mA output signal.
Installation Requirements Mount on DIN rail; connect LVDT sensor wiring; wire output loop to controller; calibrate zero and span.
Usage Notes Use 3-wire shielded cable for LVDT; calibrate against calibrated position reference; check loop continuity.
