PID- temperature regulator for wall surface mounting
(131 x 91 mm)

 

Universally configurable temperature regulators for wall surface mounting.

Can be used as a fast, precise and complex multi-channel regulator with PID regulating functions and many extras.

This series is particularly suitable for controlling heating and refrigeration processes in technical environments where quick and precise regulation is necessary. It offers many different programming possibilities for controlling compressors, heating elements, alarms, etc.

 

Can be used as:

  • Regulators with up to 6 freely programmable relay outputs.
  • Regulators with 2 sensor inputs, to control the differential temperature (room temperature regulation).
  • Regulators with 3 sensor inputs, to control 3 independent circuits (also possible on the basis of room temperature).
  • Regulators with up to 5 digital inputs:
    - configurable e.g. as fault alarm contacts to report faults in plant components such as high-pressure or low-pressure pressostats etc. (visual or acoustic alarm or via relay contact),
    - configurable to switch between 2 target values (day/night) via an external switch.
  • Regulators with programmable buttons, e.g. to switch downstream plant components on or off.
  • Regulators with temperature alarm to monitor a predefined temperature (visual or acoustic alarm or via relay contact).

 

Features:

  • PID regulating functions
  • Easy operation via three work levels
  • Automatic parameter storage without data loss when a power-cut occurs
  • Freely selectable target temperature and hysteresis
  • Hysteresis adjustable either in one direction or symmetrically
  • LED display of operating status
  • Target temperature and upper/lower hysteresis limit freely adjustable
  • Heating / cooling interchangeable
  • Lockable buttons to prevent changes to target temperature
  • Alarm in the event of sensor short-circuit/sensor fault
    (adjustable relay switching state in event of fault)
  • Switchable between °C or °F display
  • Separately adjustable minimum action time and minimum pause time for output relay
  • Outputs as switching relays, semiconductor relays or analogue 0..10 V
