Description
Voltage supply: 18 ... 30 VDC
Digital output Q1
Configurable npn-or pnp transistor, max. load
100mA*.
Max. voltage must be less than the supply voltage
Freely adjustable ranging from 0.1 to 3000
ml/pulse in 0.1 ml/pulse steps,
Configurable output of 0V or 24V when pipe is
empty.
Configurable output of 0V or 24V
Configurable output of 0V or 24V when reaching
upper or lower limit
Configurable output of 0V or 24V when liquid flows
in negative direction.
Ground: 0 V
Digital output Q2
Configurable npn- or pnp-transistor, max. load
100mA*.
Max. voltage must be less than the supply voltage
Configurable output of 0V or 24V when pipe is
empty.
Configurable output of 0V or 24V
Freely adjustable ranging from 0.1 to 3000
ml/pulse in 0.1 ml/pulse steps.
Configurable output of 0V or 24V when flow
reaches upper or lower limit.
Configurable output of 0V or 24V when liquid flows
in negative direction.
4 ... 20mA; 0 ... 20mA
Example: 0l/min =>
6l/min => 20mA (depending on
Empty pipe
Communication interface
Digital input I1
Starts the dosage by a rising edge of 24V.
The Offset is set by a rising edge of 24V.
Reset of the counter by a rising edge of 24V.
Creeping suppression is deactivated as long as
there are 24V at the input.
