  • CHA6-SSR,  one SSR output + one SSR alarm + one Relay alarm output, 85-265V AC/DC
  • CHA6-INR,  one 4-20mA output + one Relay alarm output, 85-265V AC/DC
  • CHA6-DC10, one 0-10V output + two Relay alarm output, 85-265V AC/DC

Digital temperature controller available in full size: CHA4(48*48mm), CHA6(96H*48Wmm), CHA8(48H*96Wmm), CHA7( 72*72mm), CHA9(96*96mm).

Main Features

  • Multiple temperature sensor signals TC(K, J, E, S), PT100; Cu50, 4-20mA, 0-10V signal can be customized.
  • Max accuracy 0.3%F.S, sampling speed ≤ 300ms.
  • Auto-tuning PID control, easy to operate. Special cold junction compensation makes the temperature reading more accurate.
  • 6 alarm modes(high alarm, low alarm, absolute high alarm, absolute low alarm, interval alarm out of interval alarm) optional.
  • Be applicable with universal AC 85~256V or DC 24V power supply. And have a variety of dimensions for the customer to choose.
  • Application for  oven control, homebrew temperature control, kiln temperature control, boiler temperature control,heater temperature control
