Intrinsically safe output
For intrinsically safe installations wire the transmitter as shown in
.
Note
Make sure the instruments in the loop are installed in accordance with intrinsically safe field
wiring practices and system control drawings when applicable.
Figure 4-6. Wiring Diagram for Intrinsically Safe Installations (HART)
For HART communication, a minimum load resistance of 250
within the loop is required.
For maximum load resistance see
.
The power supply voltage ranges from 16 Vdc to 30 Vdc.
