Description
The new DPC III temperature controller series currently consists of several standardised temperature controllers which are suited to (trace) heating applications. The Digital Controller monitors measuring circuits for sensor failures, interruption or short circuit and under-range and over-range measurements in order to ensure process reliability. The DPC III can be used universally as an ON/OFF (two-position) or PID controller. The integrated power pack with widerange voltage allows the devices to be used practically anywhere in the world.
Structure
Like the predecessor model DPC, the DPC III is integrated in a snap-on housing for TS 35 DIN rail mounting. Pt 100 resistance thermometers and thermocouples are connected at the measuring input. The controller is equipped with a 16 A load relay for two-position control, an 8A group error message relay, a logical voltage output for the PID control and two settable digital inputs. The voltage for the controller is supplied through an integrated power pack with wide-range voltage. The electrical connection is established with terminal screws operating on the screw cage clamp principle. The DPC III Controller is completely downwardly compatible with the previous DPC Controller.
Function
Changes in temperature in the Pt 100 sensor are evaluated in the DPC III and are visible as temperature readings on the LED display. If a deviation from the preset level is detected, the device regulates the heating circuit of the trace heating in accordance with the pre-selected control characteristic (ON/OFF or PID). An auto-tuning function is available for the PID control and this analyses the control path (heating circuit) and automatically determines and saves the PID control parameters. The control’s output power can be displayed at the touch of a button. One of the benefits of this function is the possibility of evaluating the quality of the heating circuit. There are more factory-fitted switching points for use as alarms for too-high or too-low temperatures. When servicing the heating circuit, the control output can be switched off at the touch of a button on the device or through digital input and there is the option of disabling the temperature alarms. The process reliability is further enhanced by the control circuit’s additional monitoring functions and the connected measurement sensor. The programming interface allows the device parameters to be read out with a code key and transferred to other controllers. For effective parameter protection a multi-stage password management system can be activated. Furthermore, the manual control or soft start functions can be activated for the system start-up.
