Smart transmitters are designed to provide enhanced capabilities for process measurement and control. They can transmit process information in multiple formats. The correct answer reflects the ability of smart transmitters to utilize both digital communication formats and the widely-used 4-20 mA analog format. This capability allows for more efficient communication and increased accuracy, making them valuable in various industrial applications.

While some transmitters may primarily focus on digital transmission, most smart transmitters are built to offer versatility, combining both digital and analog formats. This ensures compatibility with existing systems and improves overall data transmission quality. A limited focus on only one format would reduce the effectiveness and utility of smart transmitters in diverse operational environments.

The other choices do not account for the full range of capabilities provided by these devices, as smart transmitters are not restricted to just one type of format, and specifically, the 20-100 mA option is generally not standard for smart devices. Therefore, the comprehensive functionality of smart transmitters enables them to effectively transmit information in both digital and the 4-20 mA analog format.
