Digital output 1 (Menu item 4.2)
You have the following setting options in this menu:
● Function, menu item 4.2.1
You can configure digital output 1 as a pulse, frequency, alarm or status output
When "Split value active" is selected, the output is active when the current level of the
flow value is within the lower subdomain 0 to
"Split value"; the output current is then scaled to the 0 to "Split value" range. If the flow
value exceeds this subdomain, the output current is scaled to the 0 to URV range.
● Signal type, menu item 4.2.2
You can configure different signal types for the output signal of digital output 1:
– Active:
The device-internal voltage is used (+24 V).
– Passive:
