ALTOSONIC V
ELECTRICAL INSTALLATION 3
3.8 Connecting the outputs of the UFP-V I/O-rack
The I/O signals are wired to the connection terminal. This terminal is client specified, therefore
only an example can be given.
Connector X1 Flow Computer UFP-V I/O-rack
This is an example, position numbers may differ, see connection diagram supplied with
flowmeter.

Current output
MP103 card
DB9 Connector 3
Active(0..22mA): R load < 500 Ohm
Passive : Uext= 8.1…30V
R load = (Uext- 8V) / 22mA
I = 0..22mA
Pulse outputs
MP103 card
DB9 Connector 3
Selectable by jumper setting on MP103 card
24V
: Imax-out = 10mA, Ri=2k4
12V : Imax-out = 5mA , Ri=2k4
Open Collector: Umin = 1V, Imax =10mA
