Flow Meter FC01-LQ Flow Meter FC01-LQ
Technical data 49 Technical data 49
Inrush current: I
p
= typ. 3 A (20 µs)
Switch-off current: I
kipp
= typ. 0.75 A
Rated power consumption: P
n
= 4.1 W with zero flow, voltage outputs
P
n
= 4.8 W max. flow (end of measuring range),
voltage outputs
Insulation voltage: supply input - central electronic unit ≥ DC 500 V
8.3 Analogue outputs
The analogue outputs are physically isolated from each other as well as from the electronic
control unit FC01-LQ.
Pin selection for analogue outputs V1, V2 and C1
Signal name Pin XAO
NC 1
analogue output 1 - flow rate 2
reference ground 1 3
shield 1 * 4
shield 2 * 5
analogue output 2 - temperature 6
reference ground 2 7
NC 8
NC - not used
Analogue output 1 - ANA OUT FLOW (flow output)
Analogue output 2 - ANA OUT TEMP. (temperature output)
* Shield ungrounded - apply on one side only.
The output is reverse polarity protected.
