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
= DC 42 V; 5 A
For the external power supply a separate switch is required.
9.2 HART
®
loop display (DIH50, DIH52)
Additional configuration 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 configured 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.
