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
B
= 42 V (DC): 5 A
For the external power supply a separate switch is required.
9.2 HART
®
loop display (DIH50)
Additional configuration of the temperature transmitter with a HART
®
Loop Display (model DIH50) is possible. This is used for the local
display of the current process value. The unit and the configured
measuring range of the transmitter are automatically updated via
the HART
®
protocol in the display. No further change of the HART
®
loop display (DIH50) is necessary. To do this, the DIH50 must be in
HART
®
mode.
