see Page 37 ff.
85...260 V AC, 45...65 Hz
20...55 V AC, 45...65 Hz
16...62 V DC
No measures necessary.
Power supply and signal cables (inputs/outputs):
• Cable entry M20 x 1.5
or
• Cable gland for cables with dia. 6...12 mm
• Threaded adapter 1/2" NPT, G 1/2"
Sensor cable connection (see Fig. 41 on Page 40):
A special cable gland allows you to insert both sensor cables (per channel) into the
connection compartment simultaneously.
• Cable gland M20 x 1.5 for 2 x dia. 4 mm
or
• Threaded adapter 1/2" NPT, G 1/2"
See Page 40
AC: < 18 VA (incl. measuring sensors)
DC: < 10 W (incl. measuring sensors)
Switch-on current:
• Max. 13.5 A (< 50 ms) at 24 V DC
• Max. 3 A (< 5 ms) at 260 V AC
Lasting min. 1 cycle frequency:
• EEPROM or T-DAT save measuring system data if power supply fails.
• T-DAT saves the configuration/setting values of the transmitter.
If necessary, the T-DAT data can be loaded into the EEPROM (manual save function).
