6.2.6 Specifications of a remote flow sensor connected to a
8025 Batch in panel version
Signal from the remote sensor
• type • pulse, sine-wave (typical sensitivity 50 mV peak-to-peak at 250 Hz),
"on/off", or standard voltage 0...5 V DC
• frequency • 0,6...2200 Hz, can be parametered
• max. voltage • 36 V DC
Input impedance
depends on the position of selector "LOAD" on the electronic board of the
8025 Batch in panel version. See chap. 8.7 and 8.9.
Power supply
• dosing controller supplied
with a 12...36 V DC voltage
supplied by the dosing controller depending on the position of selector
"SENSOR SUPPLY" of the 8025 Batch in panel version, either:
• 5 V DC, 30 mA max.
• (L+) – 12V: supply voltage (L+) of the dosing controller minus 12 V DC
(minus 12,5 V DC max.), 80 mA max.
• L+: supply voltage (L+) of the dosing controller (minus 1,5 V DC max.),
140 mA max.
