By selecting the next higher pulse number from the above table (1 litre per pulse) the user will make
sure that the pulse output frequency will not exceed (for the specified Q
100Hz and, at the same time, verify the selection of the pulse length (5ms). The user may choose the
V values other than those from the basic selection in the above table, e.g. 0,5 litres/pulse.
Passive output
FLONET FH30xx
Imax = 30mA
Shielded cables must be used to connect the output signals.
The shield is only connected on one side, namely the PE terminal located on the terminal board.

5.6.2 Current output 4 to 20mA

Functions and parameters
• Passive current output electrically insulated from the ground and other inputs and outputs
• Umax = 30V
• Rzmin = 250
• Programmable function:
o Volume flow rate
• Fixed current setting in the range of 4 to 20mA
In cases of power cut, the current output will preserve the last value prior to the power
failure.
