Power supply
Terminal assignment
Supply voltage 85 to 260 V AC, 45 to 65 Hz
20 to 55 V AC, 45 to 65 Hz
16 to 62 V DC
Power consumption AC: <15 VA (including sensor)
DC: <15 W (including sensor)
Switch-on current :
• Max. 13.5 A (< 50 ms) at 24 V DC
• Max. 3 A (< 5 ms) at 260 V AC
Power supply failure Lasting min. 1 power cycle:
• EEPROM saves measuring system data if the power supply fails
• HistoROM/S-DAT: exchangeable data storage chip with sensor specific data
(nominal diameter, serial number, calibration factor, zero point, etc.)
Electrical connection
a0007808
Connecting the transmitter, cable cross-section: max. 2.5 mm

a Cable for power supply: 85 to 260 V AC, 20 to 55 V AC, 16 to 62 V DC
Terminal No. 1: L1 for AC, L+ for DC
Terminal No. 2: N for AC, L- for DC
b Signal cable: see Terminal assignment →  6
c Ground terminal for protective conductor
d Ground terminal for signal cable shield
Potential equalization No special measures for potential equalization are required. For instruments for use in hazardous
areas, observe the corresponding guidelines in the specific Ex documentation.
Cable entries Power-supply and signal cables (inputs/outputs):
• Cable entry M20 × 1.5 (8 to 12 mm / 0.31" to 0.47")
• Thread for cable entries, ½" NPT, G ½"
