- Certificates of approval for use in wide range of hazardous industrial environments internationally
Either of the input signal paths, analog or digital, can be utilized as the command source. When analog is selected as the input source, the 4-20 mA signal is considered the command signal. Selecting the digital source causes the level of the 4-20 mA input to be ignored and the signal sent via HART serves as the input command signal.
The software based units deliver enhanced functionality for in-field setup and calibration, as well remote monitoring and setup via HART. Multiple operating modes are accessible to the user to properly characterize valve position to desired curves, one of which can be customized. An analog feedback signal of the stem position is provided as an output.
