4 Wiring the XNX transmitter

Personality circuit boards determine the XNX behavior based on the sensor type

attached to the XNX interface.

The table below deﬁnes the three XNX transmitter conﬁgurations and the sensors

each support.

4.1 General Wiring Considerations

For proper operation of the XNX Universal Transmitter and Sensor Technologies,

consideration of wiring induced voltage drops, transient electrical noise and

dissimilar Earth ground potentials is imperative in the design and installation of

the system.

NOTE:

EMI note for applications using shielded cable: Cable shield must provide 90%

coverage of the wiring. Cable shield terminations must be made at the cable

glands with suitable EMI-type glands. Avoid terminating cable shields at the Earth

ground lug inside the XNX enclosure. Where wiring is in pipe, a shielded cable is

not required.

Wiring for DC Power, 4-20mA Signal, remote wiring to sensors must be sized

sufﬁciently to provide sufﬁcient voltages for the line length and the loads that will

be used.
