Core functions
Precise temperature control
Measurement range: -200℃ to +1800℃ (supporting K/J/T/E/N/R/S/B type thermocouples and PT100/RTD).
Resolution: 0.01℃ (low-temperature range), 0.1℃ (high-temperature range).
Accuracy: ±0.1% FS (full scale) or ±0.5℃, taking the maximum value.
Multimode control
PID control: Adaptive PID algorithm, suppressing overshoot (P/I/D parameters can be manually adjusted).
ON/OFF control: Relay output, supporting hysteresis setting.
SSR driver: Supports solid-state relay (SSR) pulse output (12V DC/24V DC optional).
Multi-segment programming
Programmable 30-segment temperature curves, supporting slope heating/cooling (slope range 0.1-999.9℃/min).
2. Hardware characteristics
Input/output interface:
Input: Compatible with thermocouple /RTD/ analog quantity (4-20mA/0-10V), automatically recognizes sensor type.
Output: Relay (250V AC/5A), SSR drive, analog output (optional 4-20mA or RS485 Modbus).
Display and Operation
Screen: 5-inch TFT LCD screen, real-time display of temperature curve, set value, and dual display of PV/SV.
Keys: Waterproof and dustproof membrane keyboard, supporting quick parameter setting.
Structural design
Protection grade: IP65 (front panel), suitable for damp and dusty environments.
Dimensions: 96×96×110mm (panel installation), material: aluminum alloy +ABS engineering plastic.
3. Intelligence and expansion functions
Communication interface:
RS485: Supports Modbus RTU protocol and can be connected to PLC/DCS systems.
USB: Data export (CSV format), supports firmware upgrade.
Alarm function:
Dual independent alarms (upper limit/lower limit/deviation alarm), relay/buzzer optional.
Self-tuning
One-click AT (Auto-Tuning) function, automatically optimizing PID parameters.
4. Safety and Reliability
Electrical isolation: Three-terminal isolation of input/output/power supply (withstand 1500V AC).
Anti-interference: EMC complies with the IEC61000-4 standard, suppressing electromagnetic interference.
Certification: CE, UL, RoHS certification, meeting industrial-grade EMC/EMI requirements.
