HARDWARE (Continued)<br />
Auxiliary output supply: An auxiliary output supply of 24 Vdc at<br />
200 mA is available at terminals on the input and output rails.<br />
This is in addition to the full complement of inputs, outputs, NDP<br />
or GDP+, and an external 2-line display panel. If the modem is<br />
in use, it consumes the equivalent of 20 mA maximum (reduces<br />
auxiliary output supply to 180 mA).<br />
If more current is required from the auxiliary output supply, it can<br />
be compensated for by reducing input consumption.<br />
The auxiliary output supply is part of a 24 Vdc supply protected<br />
by a 500 mA self-resetting thermal device (effectively 380 mA at<br />
maximum temperature, 45 °C, 113 °F). This protected supply<br />
powers the inputs and the auxiliary output supply.<br />

The current sensor, I, is IQ powered. For an externally powered<br />
current sensor, the channel should be linked for I, and connected<br />
as a voltage input, V.<br />
