This series multi-slope intelligent temperature controller (with RS485 module choose intallation ) which our company produce  ,the production  process was strict controller by CE standard , ,there are five steps after instrumentation PCB- pluging and SWD- omponents welding , for lower temperature handle-higher temperature handle-power handle-professional instrument test validation –load detection output control .To ensure the hardware of products with wide range of anti-harmonic interference and component parameters of instrumentation in critical point have  stable performance and longer work-life in high or low temperature environment  conditions.



  1. Multi-section control temperature program ,1-32 section can to define heating and cooling  curves and application of different work ambient work that heating and cooling
  2. The rise-down or constant temperature keep time between 1 and 9999 min, according to the  require .
  3. To choose control temperature display value 0.1°C(or1°C)when e value lees  than 1000°C (with sensor type)
  4. Control  temperature software optimization PID intelligent control all range accuracy of temperature upto±0.1°C.
  5. To choose install RS485 full isolation communication module ,supporting PC,PLC compositiona a remote many point to bus-intelligent control system ,adopt sup-standard MODUS communication protocol(RTU+), support all industry controller assemble software.
  6. AC80-260V wide range of witching power ,for wide ranger of voltage ,the stronger ability anti-interference of harmonic ,a good stability .It can work in different environment conditions.
  7. The components adopts SMD  production process ,low heat in the working ,components parameters in critical point have stable performance and long work-life.
  8. Thermocouples ,thermal resistance simulation and many standard signal free input ,range set free.
  9. Master –control output type choose:“R”-relay contacts driver AC contact ;“S”-zero pluse trigger driver signal ,three-pluse SSR;“L”-simulation continuous power current 4-20 MA, driver signal ,three-phase adjust the pressure module.
  10. Tow-line alarm contacts stand alone output,12 type up-down limit alarm user may free choose to use.


Technical index

  5. The temperature control type:

Intelligent self tuning control ,for PID value of the initial value ,adjust PID parameters when the temperature fluctuations near the critical point.

Time proportional control ,set :L=0  D=0,unchanged P parameter

ON/OFF control ,set : P=0 ,set HY return difference for  

Upper-down area control value

       6.Output control:

Switching control:“R”-the voltage of relay contact (standardAC220v);“S”-12VDC pulse voltage .

Simulation control:“l”-0-10MA continuous current ;4-20MA continuous current ;“U” -0-5VCD ,1-5VCD continuous voltage.
