Introduction to DAEYANG ELECTRIC 8251772
8251772 Product Overview
The DAEYANG ELECTRIC 8251772 is a high-precision intelligent temperature controller, developed by DAEYANG ELECTRIC (Deyoung Tech)—a professional manufacturer specializing in industrial automation control instruments. Tailored for temperature regulation in diverse industrial processes such as plastic molding, food processing, pharmaceutical production, and electronic component manufacturing, it serves as a core control unit to maintain stable temperature conditions for production equipment and reaction systems. A standout feature is its versatile input compatibility, supporting multiple types of temperature sensors (thermocouples, RTDs) and linear signals (voltage/current), which eliminates the need for separate controllers for different measurement scenarios. Equipped with advanced artificial PID control algorithm and automatic tuning (AT) function, it achieves zero overshoot during temperature adjustment and ensures rapid response to dynamic load changes—with a sampling rate of 30 times per second and a minimum control cycle of 0.5 seconds.
