HMI Process Controller

Single-Loop PID Temperature Process Controllers

Featuring interactive touchscreen software.
Temperature process controllers offers easy to use, accurate, reliable PID control. These single loop panel mount controls include auto-tuning, a universal sensor input and PID control output.

Available in standard 1/4 DIN size, these auto-tuning temperature controllers automatically set PID control parameters for optimal system performance

Manual settings also permit on-off, P, PI or PID control modes.

  • User-defined menu system allows the user to assign up to 20 parameters in the operations menu
  • Display provides better recognition of process changes, including current process value and set value
  • Ramp to set point feature controls temperature rise
  • Includes a single alarm output as standard
