REX C400 Temperature Controller Introduction:

  • REX C400 is a digital temperature controller, which uses advanced PID control algorithm to keep the heated object at the set temperature.
  • Panel size 48*96mm or 1/8 DIN, except this size, we have 4 kinds of sizes as well, click this link to know more details.
  • Celsius or Fahrenheit indication available, so customers in most of countries in the world can use it. Also, it can be used in Bahamas, Belize, British Cayman Islands, Palau, United States of America who use Fahrenheit more.
  • Sampling cycle: 0.5 seconds, fast-speed sampling makes it control temperature precisely.
  • Multiple input(TC, RTD or analog input) and output options(relay, SSR or analog output), making it highly customizable and adaptable to different processes
