Digital output Q1
Functions:
1. Pulse
2. Empty pipe detection
3. Dosing output
4. Threshold monitoring
5. Negative flow
Digital output Q1
Can be freely set in the range of 0.1 to 3000 ml/pulse
in stages of 0.1 ml/pulse, npn or pnp transistor,
max. load 18 ... 30 V / 100mA.
Programmable output of 0 V or 24 V when measuring
tube is empty.
Programmable output of 0 V or 24 V when dosing
volume is reached.
Programmable output of 0 V or 24 V when a preset
threshold is exceeded or not reached.
Programmable output of 0 V or 24 V during negative
flow.
