Output
Output signal
PROFIBUS PA interface:
• PROFIBUS PA in accordance with IEC 61158 (MBP), galvanically isolated
• Profile Version 3.0
• Data transmission rate: 31.25 kBaud
• Current consumption: 11 mA
• Permitted supply voltage: 9 to 32 V
• Bus connection with integrated reverse polarity protection
• Error current FDE (Fault Disconnection Electronic): 0 mA
• Signal coding: Manchester II
• Bus address can be configured at the device via miniature switches, the local display (optional) or
an operating program
Low flow cutoff
Switch points for low flow freely selectable.
Galvanic isolation
All circuits for inputs, outputs, and power supply are galvanically isolated from each other.

Power supply
Electrical connections
Supply voltage
20 to 260 V AC, 45 to 65 Hz
20 to 64 V DC
Cable entry
Power supply and signal cables (inputs/outputs):
• Cable gland M20 x 1.5 (8 to 12 mm / 0.31 to 0.47 inch)
• Sensor cable gland for armored cables M20 x 1.5 (9.5 to 16 mm / 0.37 to 0.63 inch)
• Cable entries for thread ½" NPT, G ½"
Connecting cable for remote version:
• Cable gland M20 x 1.5 (8 to 12 mm / 0.31 to 0.47 inch)
• Sensor cable gland for armored cables M20 x 1.5 (9.5 to 16 mm / 0.37 to 0.63 inch)
• Cable entries for thread ½" NPT, G ½"
Cable specifications (remote
version)
Power consumption
AC: <45 VA at 260 V AC; <30 VA at 110 V AC (incl. sensor)
DC: <19 W (including sensor)
Switch-on current:
• max. 2.00 A (<700 ms) at 20 V AC
• max. 2.28 A (<5 ms) at 110 V AC
• max. 5.5 A (<5 ms) at 260 V AC
Power supply failure
Lasting min. 1 power cycle:
• EEPROM or HistoROM/T-DAT saves measuring system data if power supply fails
• HistoROM/S-DAT: exchangeable data storage device which stores sensor characteristic data
(nominal diameter, serial number, calibration factor, zero point etc.)
