Humidity: 20~85% RH, no condensation

Protection grade: front panel IP65, back wiring terminals IP30

Electromagnetic compatibility: CE industrial EMC certification, resistant to motor, frequency converter surge interference

Parameter storage: EEPROM power-off permanently saves parameters, no need for backup battery

5. Human-Machine Display and Keys

Dual 4-digit digital tubes: Upper row PV real-time measurement value, lower row SP process setting value

10 segments green LED light column: Intuitively display 0~100% PID output power ratio

Operation keys: SET setting, A/M manual-automatic switching, up and down increase/decrease keys Status indicator lights: OUT - main control output, AT - self-tuning, AL1 - alarm, MAN - manual mode

6. Mechanical installation dimensions

Panel appearance: 96 (W) × 96 (H) mm

Control cabinet opening: 92 × 92 mm

Overall depth: 95 mm

III. Product core advantages

Specialized controller for linear signals: Not limited to temperature control, can perform closed-loop PID regulation for pressure, flow, level, and gas concentration, compatible with all 4-20mA output type transmitters;

4-20mA contactless current output, with a service life much longer than relay contact output, compatible with electric proportional valves, SCR solid-state power regulation, and variable frequency fans;

5. Automation of Standalone Small Equipment

A complete closed-loop process can be accomplished without the use of PLC: Transmitter collects signals → Instrument PID calculation → 4-20mA drives the actuator, and the alarm relay serves as a safety interlock.
