Siemens SIPART DR22 Digital Process Controller

Product Code: 6DR2210

Manufacturer: Siemens


Siemens SIPART DR22 process controller is a digital controller with extended functionality. It offers a large number of prepared functions in its program memory for controlling engineering processes that the user can simply call without programming experience or other aids.

In addition and if necessary, you can easily insert function blocks for computing and logic functions in the input range of the controller. This helps you accomplish an optimal adaptation even to complex tasks.

The SIPART DR22 process controller has a sophisticated adaptation method that significantly simplifies commissioning even of critical controlled systems. The controller hereby determines the optimal control parameters independently on request without requiring the user to have prior knowledge about the process behavior. The applied method is suitable for systems with compensation and acyclic settling behavior. Even larger dead times are taken into account.

Universal use is supported by the comprehensive hardware features of the device; if necessary, the hardware can be easily expanded by a variety of signal converters (e.g. communication over a serial interface with a higher-level system). The SIPART DR22 process controller is very generously equipped with indicators. There is one analog and one digital indicator each for the controlled variable as well as the setpoint. The manipulated variable is displayed digitally. The SIPART DR22 controller can be used either as continuous controller with a current output signal or as three-point step controller for connection of electromotive drives. Split range mode of the C-controller can also be configured.

The SIPART DR22 controller can be used as:

  • Fixed-setpoint controller for control of one, two or three components, optionally also with two setpoints
  • DDC fixed-setpoint controller for control of one, two or three components
  • SPC controller
  • Slave controller (synchronous controller), optionally with internal/external switchover
  • Fixed or guided ratio controller with internal/external switchover
  • Cascade controller (dual controller)
  • Ratio cascade controller (dual controller)
  • Override controller (dual controller)
  • Dual controller with two independent control channels.
