Yokogawa Electric Corporation B9565JH Servo Motor Assembly

The Yokogawa Electric Corporation B9565JH Servo Motor Assembly drives the pen and chart positioning mechanisms in Yokogawa chart recorders and data acquisition systems. This servo-driven mechanical positioning unit is designed for internal installation as an replacement part in chart recorders, specifically Yokogawa models in the 4151/4152 series, to ensure precise recording of process variables in industrial environments such as power plants, chemical processing facilities, oil and gas operations, and environmental monitoring systems. It is used to control the movement of recording pens and chart mechanisms, supporting continuous and accurate signal tracking. A common replacement for this assembly is B9565LH-10, with other compatible variants including B9565LEVLF and B9565LC.
