Analog Output
The Digital to Analog converter (DAC) output, DAC1, on pin P3-6 outputs an analog signal
with a range of ±10 volt. The analog signal ground must be connected to the Analog Common
on pin P3-4. The 12 bit DAC has a resolution of approximately 5 mV. Refer to the IQ Master
Instruction Manual for information about the use of this output.

Monitor Output
The Programmable Monitor output allows a system variable to be monitored. The variable to
be monitored is selected in the Monitor menu, Variable Monitor Set Up dialog box. The monitor
output is a ±10 volt analog signal with 8 bit resolution. Refer to the IQ Master Instruction Manual
for information about the use of this output.

Ready Relay Output
Figure 3.11 illustrates the Ready output (P3-1), which is a normally open relay contact that closes
when the PDM is powered up if no faults exist within the PDM. Relay Common (P3-3) is the
common of this contact. This contact is rated 0.3 A at 24 VDC. The Ready output will open if a
system fault occurs.
