Analog/Digital Outputs - Danfoss VLT 8000 AQUA series Operating Instructions Manual

Analog/digital outputs

The two analog/digital outputs (terminals 42 and
45) can be programmed to show the present status
or a process value such as 0 - f
If the frequency converter is used as a digital output,
it gives the present status by means of 0 or 24 V DC.
If the analog output is used for giving a process value,
there is a choice of three types of output signals:
0-20 mA, 4-20 mA or 0-32000 pulses

45, output, pulse scaling. If the output is used as
a voltage output (0-10 V), a pull-down resistor of
470 (max. 500 ) should be fitted to terminal 39
(common for analog/digital outputs). If the output is
used as a current output, the resulting impedance of
the connected equipment should not exceed 500
0/24 V DC signal is transmitted; if used as an analoge
output, either a 0-20 mA signal, a 4-20 mA signal or a
pulse sequence of 0-32000 pulses is transmitted.
