3.6 Preparing the device for operation
WARNING
easy-RTD units are products designed for use in industrial envi-
ronments as defined in ICE/EN 6100−6-4. These products can cause
radio interference in domestic environments. In this case, the party
operating the products must implement appropriate radio inter-
ference suppression measures.
CAUTION
Installation requires qualified electrician
Arrange for an electrician to install and connect the power supply.
3.6.1 Power supply – electrical connection
The easy-RTD features an internal fuse and protection against polarity reversal. The
housing is made of plastic and serves as an insulator.
The power supply for the device is not galvanically isolated.
The easy-RTD requires a rated operating voltage of 24 V
DC
from a DC-to-DC con-
verter with safe isolation (SELV/PELV).
Rated operating voltage 24 V DC (-20%/+25%)
Permissible Voltage range Effective: 19.2-30.0 V DC (rated operating voltage -20%/+25%)
Absolute with ripple: 19.2-30.0 V DC
Battery powered: 18.0-31.2 V DC (rated operating voltage -25%/+30%)
Power consumption max. 7.2 W
Current consumption at 24 V DC: 4.7 W for basic 2.5 W for USB
