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 output up to the maximum full scale range. The flag automatically resets when within the
normal operating range unless configured to latch.
± 10V dc, 0…10V dc, 0…5V dc, 1…5V dc
Full Scale Analog Ranges (1) ± 10.5V dc, -0.5…10.5V dc, -0.5…5.25V dc,
0.5…5.25V dc
Number of Outputs 4 isolated differential
Bus Current Draw, Max 145 mA at 5V dc
75 mA at 24V dc
Heat Dissipation 2.0 total W (All points - 10V dc into 2 k - worst case
calculated.)
Digital Resolution Across Full
Range
16 bits plus sign (bipolar)
±10V dc: 15.89 bits, 330 µV/bit
0…+5V dc: 13.89 bits, 330 µV/bit
0…+10V dc: 14.89 bits, 330 µV/bit
+1…+5V dc: 13.57 bits, 330 µV/bit
Conversion Rate (all channels),
Max
120 ms
Step Response to 63%
(2)
(2) 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
Current Load Output, Max 5 mA
Load Range Output > 2 kat 10V dc
Capacitive Load, Max 1 µF
Field Calibration None required
Overall Accuracy
(3)
(3) Includes offset, gain, drift, non-linearity and repeatability error terms.
±0.5% full scale at 25 °C
