Core Features Stable Temperature Regulation: Adopts basic PID control (with manual tuning capability) to maintain consistent temperature, compatible with common industrial sensors—thermocouple (K/J/T/R/S type) and RTD (Pt100). It minimizes temperature fluctuation, ensuring deviation stays within ±1% FS ±1 digit. User-Friendly Operation: Equipped with a clear 4-digit LED digital display, which alternately shows real-time temperature and setpoint for intuitive monitoring. Dedicated function buttons simplify parameter adjustment (setpoint, alarm threshold) and mode switching, reducing learning costs for operators. Compact & Durable Design: Standard panel-mount size (typically 48x48mm, suitable for universal industrial control panels), with a front panel rated IP40 for basic dust protection. The rugged plastic enclosure resists mild industrial vibrations, adapting to general workshop environments (operating temperature: -10°C to 55°C). Essential Protection & Alarms: Built-in over-temperature alarm (relay contact output), sensor open/short circuit detection, and power-off memory (retains all set parameters after power failure). These functions prevent equipment damage and ensure process continuity. Easy System Integration: Features standard relay output (SPDT, AC250V 5A) for direct control of heating/cooling devices (e.g., heaters, fans). Simple wiring terminals and standardized interfaces enable quick connection to on-site control circuits without complex configuration.
