For the power supply, use an energy-limited electrical circuit (EN/UL/

IEC 61010-1, section 8.3) with the following maximum values for the

power supply:

for U

= DC 42 V; 5 A

For the external power supply a separate switch is required.

9.2 HART

loop display (DIH50, DIH52)

Additional conguration of the temperature transmitter with a HART

Loop Display is possible. This is used for the local display of the

current process value. The unit and the congured measuring range

of the transmitter are automatically updated via the HART

protocol

in the display. No further change of the HART

loop display is

necessary. To do this, the display must be in HART

mode.
