Proline Promag 50H, 53H
Endress+Hauser 9
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
PROFIBUS PA and FOUNDATION Fieldbus
• Non-Ex: 9 to 32 V DC
• Ex i: 9 to 24 V DC
• Ex d: 9 to 32 V DC
Power consumption • AC: < 15 VA (incl. sensor)
• DC: < 15 W (incl. sensor)
Switch-on current:
• Max. 3.0 A (< 5 ms) for 260 V AC
• Max. 8.5 A (< 5 ms) for 24 V DC
Power supply failure Lasting at least one half cycle frequency: EEPROM saves measuring system data
• EEPROM or T-DAT (Promag 53 only) retain the measuring system data in the event of a power
supply failure
• S-DAT: exchangeable data storage chip which stores the data of the sensor (nominal diameter, serial
number, calibration factor, zero point etc.)
