2.3 Features
D General
Up to four signal converters can be added to the already generously and extensively equipped, fully
functional standard controller to expand the range of application by plugging them into the slots at
the back of the closed device.
SIPART DR21 offers the following features:
D Analog inputs
T wo analog inputs for current 0/4 to 20 mA, without potential isolation
The SIPART DR21 controller can be expanded to a total of 4 analog inputs with signal
converters.
The following signal converters are available:
Use as (on) Possible signal generators
UNI-
module
AI3 (slot 1) TC/RTD/R/mV, with adapter plug also mA or V, electri-
cally isolated, permissible common mode voltage 50 V.
U/I-
module
AI3 (slot 1)
AI4 (slot 2)
0/4to20mA,0/2to10V,0/0.2Vto1V
Electronic potential isolation, permissible common
mode voltage 10 V.
R-
module
AI3 (slot 1)
AI4 (slot 2)
Resistance potentiometer
In addition, the modules from the previous program (thermocouple/mV and Pt100) can be
used (see SIPART DR20 user’s guide for wiring).
D Output structure
The SIPART DR21 controller has a y-analog output (manipulated variable) with a current
signal of 0/4 to 20 mA and a switching output with two built-in relays which are interlocked.
The relay lock can be released for a universal digital output. The relays are designed for AC
250 V, a spark quenching combination for wiring with contactors is provided.
The SIPART DR21 can be configured to operate as a continuous controller, a stepper con-
troller for motorized drives or as a two-position controller .
When used as S-controllers, the analog output can be used for outputting x, w or xd for
example.
