1/4 DIN High Performance PID Temperature and Process Controller with up to 4 Set Points and Timer Function


This powerful and versatile temperature and process PID controller meets the requirements of both the simplest and most complex processes and applications. Offered in a very short housing (only 100mm deep), it is ideal for applications where space is at a premium. Ramp/Soak control can be achieved by utilising the four set points available as well as the timer or a digital input. With the repeat function, up to 8 segment control is possible. In addition to many features being offered as standard, other options such as RS485, retransmission and Heat/Cool are also available. As well as an auto-tune feature, there is also a fine tuning option which allows the controller to be set up for optimum performance for a fast or slow response process.
  • PID Auto tuning or On/Off control can be selected
  • Fine tuning option for fast or slow response selection
  • 1/4 DIN (96x96x100mm deep)
  • 4 digit dual LED bright display
  • Accuracy:
    PT100 ±0.4°C or ±0.2% of reading + 1 digit
    T/C ±2.0°C or ±0.2% of reading + 1 digit
    Current / Voltage ±0.2% of span + 1 digit
  • 100-240V AC as standard. Contact us if you require 24V AC or 24V DC versions
  • Customer rangeable for Type K J T N E R S B thermocouple and Pt100 inputs. Alternative models for current and voltage inputs available
  • 4 set values, ramp/soak and timer selectable plus repeat function
  • Up to four digital outputs, programmable as alarms
  • Relay or Solid State Relay drive (SSR) or 4-20mA or 0-10 Vdc output versions
  • Heat/Cool PID control (option)
