DPC Front Digital Programmable Temperature Control Device Family

• Universal power supply
• Sensor monitoring
• Can be used in conjunction with Pt100 Ex, for temperature regulation in explosion-protected heating circuits

The DPCfront temperature control device series con-sists of three standardised temperature control de-vices that are adapted to the (trace) heating applications. Having two 7-segment displays, the operator can read both set- and measured temperature at first sight. By pressing a single button, the controllers power output is displayed, allowing an evaluate of the heating circuits quality. The control devices can act as ON/OFF or PID control devices. If desired, the autotuning function will automatically determine the optimum (PID) adjusting parameters for the control path. In all models the regulation can be switched off for maintenance work by pressing a single button. On account of the widerange voltage input the devices can be used almost everywhere in the world.

Application Areas:

• Industrial furnaces and dryers
• Plastic processing machines (extruders, injection machines)
• Food processing equipment
• Chemical processes
• Laboratory equipment
• Power plants
• HVAC systems
• Extruder Heating
• Hot press applications
• Heat treatment plants
• Packaging machines
• Cooling systems
• Ceramic kilns
• Incubators
• Medical equipment

Assembly

The control device is mounted into the front panel. The compact dimensions of the front (48 x 48 mm) allow a space-saving control cabinet design. The electrical connection is set up through terminal screws on the rear

Function

Temperature alterations in the sensor are evaluated in the DPCfront and shown as temperature readings on the top LED display. If the reading falls short of or exceeds the temperature value that can be seen in the bottom LED display, the output being used will automatically switch itself on or off to set the manipulated variable to the required value. To monitor the temperature, a high & low alarm function is pre-programmed. The devices detect malfunctioning at the sensor and in the control circuit and report these as faults. Each type of alarm is signalled as a group alarm via a relay
