(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.
(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. Time applies to one or both channels.
(3) Includes offset, gain, non-linearity and repeatability error terms.
(4) Output ripple is the amount a fixed output varies with time, assuming a constant load and temperature.
(5) Repeatability is the ability of the output module to reproduce output readings when the same controller value is
applied to it consecutively, under the same conditions and in the same direction.
(6)
Rated working voltage is the maximum continuous voltage that can be applied at the input terminal, including the
input signal and the value that floats above ground potential (for example, 10V dc input signal and 20V dc
potential above ground).
(7) If the optional 24V dc Class 2 power supply is used, the 24V dc current draw from the bus is 0 mA.
