ANALOG OUTPUT :
AWT20L is provided with the following outputs:
0 - 10 Vdc ( terminals 22 - 23 )
0 - 20 mA, 4 - 20 mA ( terminals 21 - 23 )
To modify the output follow the procedures at chapter ANALOG OUTPUT MODIFY.
In the standard
version in order to increase the input field up to 35 mV enter in parallel a 49,9K resistance; see
ANALOGUE OUTPUT MODIFICATION section for further details.
NOTE:
There is also another version of the AWT20L transmitter which has an output voltage of +/-5Vcc.
USE:
Normally used with a 12 bit analog / digital boards installed on programmable logic ( PLC )
