Multi-circuit controller with control panel and display

  • Integrated operating and display unit
  • Power output up to 5A at 230V
  • Comprehensive monitoring functions
  • Powerful controller functions

The CR15 multi-channel temperature controller is designed for 5, 10 or 15 temperature control circuits depending on the expansion stage and offers a complete control system in a compact aluminium housing with the following units:

  • Temperature recording with PT100 or thermal sensors
  • Control panel and display unit
  • Power outputs for direct switching of heating up to 5A
  • Communication interfaces to connect to higher level systems
  • Powerful controller functions, such as self-optimisation, monitoring functions and target value programmes


Inputs and outputs

Temperature recording:

  • Fe-CuNi or NiCr-Ni thermal components
  • Pt100 thermal resistances

Power outputs:

  • Optionally for 24VDC, 24VAC or 230VAC
  • Pulse mode, i.e. the unit is switched on and off at the zero voltage point
  • Maximum power per output 5A at 230V


Control panel and display unit

  • Reversible individual display of all control circuits (target value, actual value, control deviation, output rate, power)
  • Configuration with three stage password protection (control behaviour, limit values, communication, operating mode, ramp function)


Monitoring functions

  • Excess or insufficient temperature per control circuit
  • Sensor break, short circuit, reversed polarity
  • Defective area
  • Collective alarm as a potential-free alarm contact



  • RS485 to connect to higher level systems or to network several CR15 controllers


Controller functions

  • Self-optimising of the controller parameters (CR15+)
  • 4 target values can be activated per channel for temperature profiles
  • Ramp function
  • Heating and cooling behaviour can be configured separately
  • Automatic controller adjustment mode in the event of a sensor break
