Output Specifications

Attribute Value

Analog Normal Operating Ranges

(1)

(1) The over- or under-range flag will come on when either the High Clamp or the Low Clamp values are exceeded. When either

range flag is set, the module clamps the corresponding channel’s output to the High Clamp or the Low Clamp value. Unless

latched, the flag automatically resets when directed to a value between the High Clamp and the Low Clamp values. The

output channel value always returns to normal operation when directed to a value allowed by the High Clamp and Low

Clamp values (even if latching of the Clamp status bits is enabled).

0…20 mA, 4…20 mA, +/-10V DC, 0…10V DC, 0…5 V DC, 1…5V DC

Full Scale Analog Ranges

(1)

0…21 mA, 3.2…21 mA, +/-10.5V DC, -0.5…10.5V DC,

-0.5… 5.25V DC, 0.5… 5.25V DC

Number of Outputs Four single-ended, voltage or current

Digital Resolution Across Full Range 15 bits plus sign unipolar and bipolar

Conversion Rate (all channels) max. Interrupts not enabled: 2.5 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
