The I/O>Set Out controls which of the DXN outputs are active. The DXN output signals can be described as analog, or digital/
pulse. Analog signals change continuously over time, digital/pulse signals are present at discrete points and represent
information using a sequence of on/off pulses. For connection information see Figure 110 .
The type of I/O available from the DXN is set using check boxes. The two analog outputs are 4-20 mA and 0…10V DC output.
The pulse output has a maximum frequency of 1000 Hz and can be configured as either a rate pulse or a totalizing pulse.
Whichever output is used all outputs are scaled the same way using the I/O>Scale Out. In other words 20 mA,
1000 Hz, and 0…10V will all represent the same Maximum flow rate set in the I/O>Scale Out.
