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 unless configured to latch.

0 to 20 mA, 4 to 20 mA

Full Scale Analog Ranges(1) 0 to 21 mA, 3.2 to 21 mA

Number of Outputs 8 single-ended

Bus Current Draw (max.) 145 mA at 5V dc

185 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 2.69 Total Watts (All points - 21 mA into 250Ù - worst case

calculated.)

Digital Resolution Across Full Range 16 bits (unipolar)

+4 to +20 mA: 15.59 bits, 0.323 μA/bit

0 to +20 mA: 15.91 bits, 0.323 μA/bit

Conversion Rate (all channels) max. 5 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

Resistive Load on Current Output 0 to 500 Ù (includes wire resistance)

Max. Inductive Load 0.1 mH

Field Calibration None required

Overall Accuracy(4)

(4) Includes offset, gain, drift, non-linearity and repeatability error terms.
