Wiring The Xnx; 2�1 General Wiring Considerations - Honeywell XNX Quick Start Manual

2 Wiring the XNX

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.

Before wiring the XNX, confirm the correct personality boards and options are
installed.
2�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:
To maintain EMC integrity, wiring must be shielded by either an integral shield
or run through conduit or pipe. Shield should provide 90% coverage.
Loading
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.
Isolation
Isolating power and signal carrying conductors is recommended.
Circuit Protection
Supply circuits must provide over current protection. Class 2 power supplies are
required for 24 volt DC supply. Consider Inrush current in specifying any DC supply.
Power supply range is 16 to 32 VDC for EC and mV versions, 18 to 32 VDC for
