- The over- or under-range flag comes on when the normal operating range (over/under) is exceeded. The module continues to convert the analog input up to the maximum full scale range.
The flag automatically resets when within the normal operating range. - Step response is the 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.
- Includes offset, gain, nonlinearity, and repeatability error terms.
- Output ripple is the amount that a fixed output varies with time, which assumes a constant load and temperature.
- Repeatability is the ability of the input module to register the same reading in successive measurements for the same input signal.
- 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, a 10V DC input signal and 20V DC potential above ground at the input terminal. - If the optional 24V DC Class 2 power supply is used, the 24V DC current draw from the bus is 0 mA.
