Configuration words 64
(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.
(2) If the optional 24V DC Class 2 power supply is used, the 24V DC current draw from the bus is 0 mA.
(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.
(4) Includes offset, gain, drift, non-linearity and repeatability error terms.
(5) Output ripple is the amount a fixed output varies with time, assuming a constant load and
temperature.
(6) 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.
(7) 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).
(8) Failure to use a Class 2 power supply without regulation within these limits could result in improper
module operation.
