Multi-circuit controller with control panel and display

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

Interfaces

• 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
