This series multi-slope intelligent temperature controller (withRS485 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 temperaturehandle-power handle-professional instrument test validation –loaddetection output control .To ensure the hardware of products withwide range of anti-harmonic interference and component parametersof instrumentation in critical point have  stable performanceand longer work-life in high or low temperature environment conditions.

Characteristic

1. Multi-section control temperature program ,1-32 section can todefine heating and cooling  curves and application ofdifferent work ambient work that heating and cooling
2. The rise-down or constant temperature keep time between 1 and9999 min, according to the  require .
3. To choose control temperature display value 0.1°C(or1°C)when evalue lees  than 1000°C (with sensor type)
4. Control  temperature software optimization PID intelligentcontrol 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 tobus-intelligent control system ,adopt sup-standard MODUScommunication protocol(RTU ), support all industry controllerassemble software.
6. AC80-260V wide range of witching power ,for wide ranger ofvoltage ,the stronger ability anti-interference of harmonic ,a goodstability .It can work in different environment conditions.
7. The components adopts SMD  production process ,low heat inthe working ,components parameters in critical point have stableperformance and long work-life.
8. Thermocouples ,thermal resistance simulation and many standardsignal free input ,range set free.
9. Master –control output type choose:“R”-relay contacts driver ACcontact ;“S”-zero pluse trigger driver signal ,three-pluseSSR;“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-downlimit alarm user may free choose to use.
