Ahlborn ALMEMO 2590-2A - Programmed analog value output; Scaling the analog output

15. Output modules
71
To select the port press key(s) : <P> : ▲ or ▼
e.g. port 6 at socket A2 (port address 26):
Port: 26
The analog module appears with type and output signal 10V or 20mA:
Analog output (D/A converter external in module) :
Analog output external 10V
Reprogrammable via keys :
Analog output internal 20mA
The same output modes can be programmed as variants as with V5 :
0: Measured value of selected measuring channel :
0: Select meas channel M00
2: Measured value of a programmed channel :
2: Assigned internally M01
8: Programmed analog output (see above) :
8: Driven externally
With V6 the analog value appears with the appropriate units :
Analog value : +08.345 V
Programmed analog value output (see Manual 6.10.7)
If the analog value is to be controlled individually either manually or via the in-
terface then variant 8 ´Driven externally´ must be set :
8: Driven externally
Program the output of 2.5V with 10V output;
(see above and 8.5) :
Analog value : 05000
Scaling the analog output
In a special sub-menu that part of the measuring
range assigned to the measuring point concerned
that is actually used by the selected channel can,
with functions
Analog start
and
Analog end
, be
spread over the 10 V or 20 mA; (see 13.12.3)
Program the analog output start 6 Analog start : 0.0 °C
Program the analog output end (see 9.5) : 6 Analog end : 100.0°C
For 20 mA analog outputs only
Choose between 0 - 20 mA and 4 - 20 mA output : Current output : 4-20 mA
