1/4 Din Temperature Controller CH902 Introduction:

  • 1/4 din temperature controller (model CH902) is a 92*92mm biggest panel size digital temperature controller, it uses Proportional, Integral and Derivative(PID) algorithm to precisely realize the desired temperature of an object.
  • Input is universal, can be K, J, R, S, B, E, N, T,  Pt100, Cu50 thermocouples, out factory default input is K type thermocouple, or RTD(pt100), analog input(4-20mA, 0-10VDC).
  • PV and SV are 4 digits LED tubes, PV color is red, SV color is green, high contrast and easier to see, so it can indicate maximum 9999 degrees celsius, but in the real heating applications, the maximum temperature will be less than 2300 degrees celsius.
  • Compatible with a wide range of power sources from 85~265Vac or 24VDC voltage.
  • Among the heating process, the PID controller is the brain, while the output relay or SSR is the executive part, which controls the heating element’s heat efficiency.
