The SIPART DR21 process controller is a digital controller. Its internal program memory contains a large number of standard functions for the control of process engineering applications. A user with no programming knowledge can simply call up and execute these functions.
The SIPART DR21 controller is very flexible and can be quickly and easily configured to meet the requirements of the application.
An adaptation process is built in as standard.
The SIPART DR21 controller can be used as a:
Fixed setpoint controller for one, two or three-component control, with the option of two setpoint values
DDC fixed setpoint controller for one, two or three-component control
Slave, synchro or SPC controller, with the option of internal/external switchover
Fixed or controlled ratio controller with internal/external switchover
M/A control station, process variable indicator or setpoint transmitter. The control algorithm is disabled in these cases.
Safe separation between supply connection and field signals
Clearances and creepage paths for surge class III and pollution level 2, unless stated otherwise
EC Certificate of Conformity no. 1243.00-05/01
CE marking: conformity concerning EMC Guideline 89/336/EWG and NS Guideline 73/23/EWG is fulfilled without restrictions.
Emitted interference, immunity to interference to EN 61 326, NAMUR NE21 8/98
The SIPART DR21 controller has already acquired the following certifications:
Certification of Germanischen Lloyd, Certificate No. 97 974-96 HH
Certificate of „DIN CERTCO, Berlin“, Approval as temperature control and limiting equipment for heat generators, Certificate of Conformity with DIN 3440: 1984-07, Registration no.: TR 10692000 S
TÜV certificate on approval of a component symbol for water level controller, test requirement according to VdTÜV instructions „water level 100“ and „water level 100/1“, component symbol no. TÜV.WRS(WR).00-378K
Weight of basic unit
Approx. 1.2 kg
Housing and frame
Polycarbonate, reinforced with glass fiber
Power supply connections:
115/230 V AC
3-pin earthed plug IEC 320/V DIN 49 457A
24 V AC/DC
Special 2-pin plug
Connections for process signals
Multi-pin screw-type terminal blocks, protected against reversed polarity for cables of 1.5 mm2 (AWG 14)
Protective earth connection
A rail can be mounted on the rear panel of the power supply. The rail is included in the delivery of the coupling relay module.
The connector for the power supply and the screw-type terminal blocks for the process signals are part of the scope of the supply of the basic unit or the option modules. Exception: : 6DR2803-8C interface module and 6DR2803-8P PROFIBUS-DP module. The connectors have to be ordered separately.
