XNX Universal Transmitter
Installation and Operation
40
box in multi-node systems when used with the supplied terminal
jumpers. These jumpers enable an electrical connection without
connecting to the Personality Board. Install them between pins 1
and 2 and between pins 3 and 4 to support multi-node wiring.
Keep the total load resistance for the 4-20mA between 200 and
500Ω, including the resistance of the properly selected 4-20mA
cable and input impedance of the equipment to be connected.
Failure to perform ‘Calibrate mA Output’ or with loads outside
the recommended values may result in a diagnostic warning or
fault messages.
If the 20 mA output is not used, a 500 ohm resistor must be
installed.
The transmitter’s power consumption is dependent on the
sensor and options for the specic conguration. For proper
operation, the input voltage must be maintained between 16 and
32 VDC for EC and mV units and between 18 to 32 VDC for IR
units.

Labels applied to the back of the POD identify each of the
connection points.
Note: Pins 2 and 4 of terminal block TB1 have no internal connection on the
personality board. When used with the terminal block jumpers, pins 2 and 4 can
provide additional 4-20mA connections or supply power for daisy-chained units.
