1/16 DIN Economic PID Temperature Controller

Multiple temperature sensors (K, J, E, S, PT100, Cu50);

PID and ON/OFF Control Mode with high standard self-adjust function;

Self-adjusting function and intelligent control of the instrument to ensure long-term stability.



CHTA4 series is 1/16 din economic PID Temperature Controllers including six models:

  • CHTA4-RNR,  one Relay output + one Relay alarm output, 85-265V AC/DC
  • CHTA4E-SNR,  one SSR output + one Relay alarm output, 24V DC
  • CHTA4-RRR,  one Relay output + two Relay alarm output, 85-265V AC/DC
  • CHTA4-SSR,  one SSR output + one SSR alarm + one Relay alarm output, 85-265V AC/DC
  • CHTA4-INR,  one 4-20mA output + one Relay alarm output, 85-265V AC/DC
  • CHTA4-DC10, one 0-10V output + two Relay alarm output, 85-265V AC/DC

Main Features

  • Multiple temperature sensor signal type 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.
