7.1.4. Output functions
The configuration includes the option of two binary multifunctional outputs, electrically isolated by means of
optocouplers. The output transistors of the optocouplers are accessible via terminals 12-13 and 14-15.
These are passive outputs that need external power source. Alternatively, they can be powered by an analog
output in the fixed-current mode as described above. The binary outputs can switch on and off the 1 to 50mA
current continuously.
Default settings: Output 1: frequency output, Output 2: pulse output.
The flowmeter can be equipped with an output relay, in the menu to be found under "Relay Functions".
Electrically isolated relay contacts are accessible via terminals 1-2-3. For pulse output, both the pulse width
and the minimum gap length are set at 0.5s. To ensure correct operation of the pulse function, it is
necessary to set the pulse constant with a regard to Q
4
so that the memory block of unsent pulses never
overflows. If the pulse constant is set to too low, data will be irreversibly lost.
