Core Features High-Precision Regulation: Adopts advanced PID control algorithm with auto-tuning function, compatible with mainstream industrial temperature sensors—thermocouple (K/J/T/R/S type) and RTD (Pt100). It minimizes temperature deviation within ±0.3% FS ±1 digit, ensuring consistent process quality. Intuitive Operation & Monitoring: Equipped with a high-brightness 4-digit LED digital display, clearly showing real-time temperature, setpoint, and working status (e.g., auto-tuning, alarm) simultaneously. Dedicated shortcut buttons simplify parameter adjustment (setpoint, control range, alarm threshold) and mode switching, reducing operational complexity. Compact & Durable Design: Standard 48x48mm panel-mount size, fitting most universal industrial control cabinets. The front panel boasts an IP65 protection rating (dustproof and waterproof), adapting to harsh workshop environments (operating temperature range: -10°C to 55°C). The rugged enclosure also resists mild vibrations, ensuring long-term reliable operation. Flexible Output & Comprehensive Protection: Supports multiple output configurations (relay/SSR/analog signal) to match different heating/cooling devices (e.g., electric heaters, cooling fans, solenoid valves). Built-in dual-channel alarm functions (over-temperature, under-temperature, sensor fault) and essential protections—sensor open/short circuit detection, power-off memory (retains parameters after power failure), and surge protection—safeguarding equipment and processes. Seamless System Integration: Optional RS-485 communication interface (compatible with Modbus RTU protocol) for easy connection to PLCs, SCADA systems, or HMIs. This enables remote monitoring, centralized control, and data logging, facilitating intelligent management of production lines
