Influence of power supply

Overvoltage protection
Endress+Hauser
• Behavior in the event of overvoltage (>30 V):
The device works continuously up to 34 V DC without damage. If the supply voltage is exceeded,
the specified characteristics are no longer guaranteed.
• Behavior in the event of undervoltage:
If the supply voltage falls below the minimum value, the device switches off in a defined manner
(status same as for no power supply).

1) Product Configurator order code for "Electrical connection"
2) IP 68 (1.83m H2O for 24 h)
For valve plug: < 1.5 mm 2 (16 AWG) and Ø4.5 to 10 mm (0.18 to 0.39 in)
The device operates within the reference accuracy up to ±5 % of the residual ripple of the supply
voltage, within the permitted voltage range.
≤0.005 % of the URL/1 V
The device does not contain any special elements to protect against overvoltage ("wire to ground").
Nevertheless the requirements of the applicable EMC standard EN 61000-4-5 (testing voltage 1kV
EMC wire/ground) are met.
