To ensure the environmental ingress rating on tapered threads (NPT),
2
a non-hardening thread sealant may be used.
Thread the appropriate size adapter (M20 or ½" NPT) into the conduit

temporary plastic dust protectors (red or blue) installed and are not certified for use
in any installation.

WIRING

HART / 4-20mA Operating Ranges
The transmitter is designed to operate in a two-wire / current loop with loop resistance and
power supply voltage within the operating range for HART / 4-20 mA installations as
described in Figure 17.
Note: A minimum of 250 Ohms of loop resistance is required to support HART
communications.
�������� �������������������� = �������������� �������������������� + �������� �������������������� + ���������������� ��������������������
For all HART installations, Honeywell recommends the HART resistor to be placed on
the positive side. Voltage should not exceed 42 VDC. See the process design system
documentation for specifics.
