• Durable & Reliable: Rated for industrial use with wide operating temperature range and high-load relay capacity for demanding commercial environments.
• Temperature Control Accuracy: Uses a digital microprocessor for signal processing and data display.The controller regulates the output based on sensor feedback to maintain the target temperature within the specified range and minimize fluctuation.
• Simplified Operational Process: Features an intuitive digital interface with clear displays for PV (Present Value) and SV (Set Value).Users can easily set target temperatures or adjust parameters without navigating through overly complex menus.
• Precise PID Control: Built-in high accuracy PID chip.It controls the temperature stably via Relay Output, preventing overheating or cooling issues.
• Installation Note：Please strictly verify that your power supply voltage matches the controller specifications before installation.
