Yokogawa Electric Corporation B9628ZN Fluorescent Lamp

The Yokogawa B9628ZN Fluorescent Lamp is an internal illumination module for Yokogawa chart recorder systems, delivering steady lighting to the display and chart area to ensure clear visibility and reliable recorder operation. It is designed as an internal component replacement for Yokogawa DR130, DR231, and DR241 recorders, using a fluorescent tube lamp assembly to illuminate panels where space is constrained or ambient light is low. With an operating life of approximately 30,000 hours under typical maintenance schedules, it minimizes downtime by extending intervals between lamp changes. The lamp supports critical industrial applications by providing consistent internal lighting for accurate reading of recorded data and smooth operation of chart displays in environments such as power plants, chemical processing facilities, oil and gas operations, and other manufacturing settings. By maintaining visibility in enclosed panels, the B9628ZN helps maintenance teams and system integrators preserve recorder performance and data integrity during long-term operation. Common replacements include Yokogawa B9628ZM, B9628ZP, and B9585AH.
