These modules incorporate proprietary Allen-Bradley technology, so they
operate and perform like the latest high-performance Allen-Bradley products for
full compatibility. Four selectable filter frequencies are provided for signal/noise
optimization. For even greater convenience, they are fully configured through
software (no DIP switches), can alert the processor to a variety of errors through
status bits, and can scale input signals to user-defined ranges without any ladder
programming.
