Analog Normal Operating
Ranges
(1)
(1) The over- or under-range flag will come on when the normal operating range (over/under) is exceeded. The module will
continue to convert the analog input up to the maximum full scale range. The flag automatically resets when within the
normal operating range.
± 10V dc, 0 to 10V dc, 0 to 5V dc, 1 to 5V dc
Full Scale Analog Ranges
(1) ± 10.5V dc, -0.5 to 10.5V dc, -0.5 to 5.25V dc,
0.5 to 5.25V dc
Number of Outputs 8 single-ended
Bus Current Draw (max.) 145 mA at 5V dc
125 mA at 24V dc
(2)
(2) If the optional 24V dc Class 2 power supply is used, the 24V dc current draw from the bus is 0 mA.
Heat Dissipation 2.16 Total Watts (All points - 10.5V into 1 k

case calculated.)
Digital Resolution Across Full
Range 16 bits plus sign (bipolar)
±10V dc: 15.89 bits, 330 µV/bit
0 to +5V dc: 13.89 bits, 330 µV/bit
0 to +10V dc: 14.89 bits, 330 µV/bit
+1 to +5V dc: 13.57 bits, 330 µV/bit
Conversion Rate (all channels)
max. 5.0 ms
Step Response to 63%
(3)
(3) Step response is the period of time between when the D/A converter was instructed to go from minimum to full range until
the device is at 63% of full range.
<2.9 ms
