Output Modules
11.6.3 Analog Output
For an analog recording of measured values it
is still possible, at sockets A1 and / or A2
(2)
to
connect V5 output modules with an analog out-
put, e.g. via recording cable ZA1601-RK -1.2
to 2.0 V (see Manual 5.1.1) and to configure
these in the
"Output modules"
menu.
The new V6 relay trigger analog adapter
ZA8006-RTA3 offers, at ports 4 to 7, the option
of up to 4 additional separately configurable ana-
log outputs; (see 11.6.2),
with the following possible output signals :
Voltage 0 to 10 V
0.5 mV / digit
Current 0 to 20 mA
1 µA / digit
Programming
is as for relay and trigger inputs :

The following output modes
can be programmed as variants :
0: Measured value for the selected measuring channel :
0: Selected meas. chan. M00
2: Measured value for a programmed channel :
2: Assigned internally M01
8: Programmed analog output (see below) :
8: Driven externally
The analog value appears below this
with the appropriate units :
Analog value : 12.456 mA
The
measured value for the selected measuring channel
Mxx is output in
variant 0. In this mode the semi-continuous measuring rate (see 11.1.3) is the
most suitable because in this way the analog output will be processed most
frequently.
Assigning an analog output to a measuring point
In variant 2 "Assigned internally",
after selecting the Mxx function, you can program the measuring point
to be output :
2: Assigned internally M
In this case the continuous measuring rate (see 11.1.3) is better.
Scaling the analog output
When configuring a measured value output it is also possible, in the same
menu, by means of the functions
"Analog start"
and
"Analog end"
, to have
the measuring range actually used for the measuring point concerned spread
over the full 10 V or 20 mA; (see 11.4.4).
To program the analog output start :
6 Analog start : 0.0 °C
To program the analog output end
(see 9.5) :
6 Analog end : 100.0 °C
For 20 mA analog outputs only
To choose between 0 - 20 mA and 4 - 20 mA output:
Current output: 4-20 mA
