Siemens SIPARTDR21 process controller is a digital controller. It offers a large number of prepared functions in its program memory for controlling engineering processes that the user can easily use as a basis without programming experience or other tools.
SIPARTDR21 has a modular structure, is easy to convert and retrofit and is therefore service-friendly. The basic unit is already fully functional with numerous features. To expand the range of application, additional modules can be inserted into the slots on the back of the closed device.
Application
The SIPART DR21 controller is very flexible in its use and can be easily and quickly adapted to the respective task. An adaptation method is installed by default.The SIPART DR21 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
- Slave controller, synchronous controller or SPC controller, optionally with internal or external switchover
- Fixed or guided ratio controller with internal/external switchover
- Master and manual control system, process indicator or setpoint sensor. The control algorithm is turned off here.
