• Diagnostic function for detection of wiring errors
• Up to 3500 W per control zone
• Counter for hours of operation
• Continual error monitoring
• Connectors of thermocouples and heating elements physically separated
• Retrofitting of up to 15 control zones is feasible
• Optional with serial interface for connection of injection moulding machines by ARBURG, ENGEL, KRAUSS-MAFFEI, FEROMATIK, etc.

Multi-channel temperature control cabinet DPT multi zone for operation with multiple tools with a high number of cavities.

This new development especially for the operation of multiple tools with a high number of cavities offer a comprehensive range of functions:

• Expandable from 40 up to 150 control circuits (in steps of 5), the LCD touch-screen display guarantees the simplest operation for highly complex tools.
• The control is executed by means of a Windows software.
• Graphic tool display with freely moveable display fields.
• Full-text error messages.
• Log files for monitoring errors and status.
• Possibility of managing two tools separately.
• Print function for temperature records.
• Various remote maintenance possibilities via standard PC interfaces.

Controller eValve-4
The controller "eValve-4" is able to control up to four bistable electromagnets, which are used for nozzles with needle valve. The electrical lift magnets generate a mechanical lift of 10 mm. The two end position are fixed with permanent magnets. Electric power is only used for changing the position of the magnetic fixed lifting cylinder.
