Designed to offer outstanding performance in an affordable package providing a complete solution for a wide variety of applications, this range guarantees extremely easy access to parameterization and operation in a high quality unit.

Despite their advanced features, the controllers are easy to use and apply and may be customised for ease of operation. Full autotune is provided.

Ramp-soak timer and soft start

A ramp soak timer is provided for time based profiling of temperature sequences. These can be used to gradually vary the temperature in a control zone before maintaining it at a defined level, and is typically used to avoid the dangers of damage due to thermal shock.

Overshoot elimination

The unique cutback system ensures precise control to setpoint and when correctly tuned inhibits temperature overshoot.

Ideal for:

  • Precision PID controller
  • Plastics Extrusion
  • Food and Beverage
  • Furnaces and Ovens
  • Incubators
  • Laboratory equipment


  • Easy to integrate and use in new and legacy applications
  • Fast-acting alarms to protect against overpressure
  • Responsive, precision PID control with overshoot inhibit
  • Easy, effective auto-tune
  • Universal + strain gauge inputs
  • Second input for differential pressure indication / control
  • Analogue retransmission
  • Easy and flexible configuration via PC software or front panel
  • Modbus RTU digital communications
