Key Features

Specialized tacho signal processing board, delivers stable high-precision speed feedback for large AC/DC motor closed-loop control.

Wide 0–20kHz frequency input range adapts to low and high speed motor MPU pickup sensors.

Full galvanic isolation for all input channels eliminates ground loop interference and pulse signal distortion.

Multi-terminal signal wiring design simplifies on-site tachometer sensor wiring layout and maintenance.

Front indicator LEDs display signal input status for quick judgment of sensor and wiring faults.

Standard rack plug-in structure supports direct one-to-one replacement without complicated wiring modification.

Anti-corrosion coated PCB resists dust, humidity and vibration in heavy industry drive control rooms.

Ultra-stable signal conversion ensures motor speed steady regulation and avoids speed fluctuation during load changes.
