This illustration shows the connections available on each of the
terminal blocks for each type of personality board�

Figure 35. XNX Personality Board Terminal Block Legend
Each of the personalities use a single terminal block for
connection with the exception of the IR personality, which
requires a second terminal block�
The personality boards also provide a dedicated pair of jumper
switches to define output of the transmitter as isolated 4-20mA,
Sink 20mA, or Source 20mA as well as a service jumper to allow
power to the loop to continue when the transmitter is being
serviced� A separate connector is used to activate local HART
(see Section 2�3�1)�
Local HART provides an external access to control the
transmitter� An intrinsically safe (IS) barrier inside the transmitter
allows the user to attach an external hand-held interrogator
for programming and configuration� The external interface is
intrinsically safe� It is installed in the transmitter's lower left
cable/conduit port�

Note: Open loop faults are not available due to HART, Modbus, and
Foundation Fieldbus interfaces where a 4-20 signal cannot be used.
In this case, open loop, 0mA must be used as the diagnostic.
The Option circuit boards vary depending upon the option
selected when ordered� Only one of the three available interface
options (relays, Modbus, or Foundation Fieldbus) can be
attached to the XNX transmitter� When installed, connections to
the options are made to connectors at the bottom of the POD�
