WARNING
RTD units are products designed for use in industrial environments
as defined in ICE/EN 6100−6-4. These products can cause radio inter-
ference in domestic environments. In this case, the party operating
the products must implement appropriate radio interference sup-
pression 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 RTD features an internal fuse and protection against polarity reversal. The hous-
ing is made of plastic and serves as an insulator.
The power supply for the device is not galvanically isolated.
The RTD requires a rated operating voltage of 24 V
DC
from a DC-to-DC converter
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: 18.0-31.2 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 mod-
ule
