Scaling The Analog Output - Ahlborn ALMEMO 2590-2 Operating Instructions Manual

14. Output modules
This gives, depending on the analog output, the following output signals :
Voltage output
Voltage output
Current output
In variant 2 ´Assigned internally´, after selecting the Mxx function,
it is possible to program the measuring point to be output :

Scaling the analog output

In a special sub-menu that part of the measuring
range assigned to the measuring point con-
cerned that is actually used by the selected
channel can, with functions Analog start and
, be spread over the 10 V or 20 mA;
Analog end
(see 12.12.3)
Program the analog output start
Program the analog output end (see 8.5) :
For 20 mA analog outputs only
Choose between 0 - 20 mA and 4 - 20 mA output : Current output : 4-20 mA
Programmed analog value output
If the analog value is to be controlled individually either manually or via the in-
terface then variant 8 ´Driven externally´ must be set :
Program the output of 2.5V with 10V output;
(see above and 8.5) :
V6 output modules
The new V6 relay trigger analog adapter ZA8006-
RTA3 (see Manual 5.1.3) offers the option at
ports 4 to 7 of up to 4 separately configurable
external analog outputs (see 14.2).
To select the port press key(s) :
e.g. port 6 at socket A2 (port address 26):
The analog module appears with type and output signal 2V, 10V or 20mA:
Analog output (D/A converter internal in device) : Analog output internal
Analog output (D/A converter external in module) : Analog output external 10V
The same output modes can be programmed as variants as with V5 :
0: Measured value of selected measuring channel :
2: Measured value of a programmed channel :
8: Programmed analog output (see above) :
With V6 the analog value appears with the appropriate units :
