Yaskawa HC-TN085V4B15A Current Sensor Transformer

The Yaskawa HC-TN085V4B15A is a compact PCB-mounted current sensor module that sits inside Yaskawa inverter and servo drive systems to measure motor current and feed an analog signal back to the drive’s control circuitry. Belonging to the HC-TN series, it uses a 4-pin interface and provides an analog output proportional to the measured current, with installation intended for internal mounting inside the inverter or servo drive rather than as a standalone device. This current sensor enables real-time motor current feedback for precise control, protection, and monitoring in applications such as variable frequency drives, servo systems, CNC machinery, welding equipment, and general motor control. Key details: Manufacturer Yaskawa Electric; Model HC-TN085V4B15A; Product Type Current Sensor / Current Transformer; Series HC-TN; Origin Japan; Construction compact PCB-mounted sensor module; Function measures motor current and sends feedback to the control system. Common replacements include HC-TN100, HC-TN125, HC-TN200 series (matching rating) or other HC-TN variants with the same connector and calibration.
