  • Product Details
  • FAQs

The dry temperature controller for rail transit is a type of temperature controller specially designed for special fields such as subways, locomotives, aviation, etc; The characteristics of this temperature controller are strong anti-interference ability, large output contact capacity, complete functions, LCD interface with illustrations, simple setting, and easy operation; Has reliable EMC and EMI performance. Our rail transit temperature sensors can be customized, using conventional PT100 temperature measurement or internationally leading fluorescent fiber optic temperature measurement; Fluorescent fiber optic temperature measurement completely cuts off the interference of temperature measurement components transmitted to the temperature controller from the temperature measurement source.


Product Characteristics

1. The protection level is IP54.
2. The contact output capacity is large.
3. The temperature controller uses an ARM architecture CPU with strong data processing capabilities and stable system performance.
4. Large screen LCD screen, digital and Chinese display, button operation, LED signal indication display.
The circuit board design concept of the temperature controller is modular design, with strong and weak electrical separation to avoid spatial crosstalk.
6. The temperature controller contains a clock chip, an external FLASH, customizable large capacity, and historical data storage with time markers.
7. Carrying communication function, the communication protocol is an internationally open standard protocol Modbus RTU or Profibus DP
