The SIPART DR21 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.
For all standard tasks, with comprehensive display functions.
Process controller in 72 × 144 mm format, ideal for standard tasks with comprehensive display functions. Various control functions and status messages.
- Good trend recognition through analog display of x and w
- Designed by default as C-controller (0/4 … 20 mA) and S controller (relay, DQ)
Design
SIPART DR21 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 rear of the closed device.
Slot assignment:
- Slot 1: Analog input 3 (AE3)
- Slot 2: Analog input 4 (AE4)
- Slot 3: Binary inputs and outputs (BE/BA)
- Slot 4: Interface module
The basic unit consists of:
- Front module (operator control and display unit with main circuit board and CPU)
- Rear panel module
- Polycarbonate enclosure with clamping elements for installation in control panels, consoles or machines
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.
