FAQ What is the main difference between the KFD2-ST2-Ex2 and its replacement, the KFD2-STC4-Ex2?The newer KFD2-STC4-Ex2 generally offers a more compact design, wider operating temperature range, and enhanced diagnostic features like line fault detection, providing more robust performance and easier troubleshooting. Can this module be used with non-SMART (HART) transmitters?Yes, it functions perfectly as a standard 4-20mA isolated barrier for non-SMART transmitters. The HART pass-through capability is an additional feature that will simply not be used in such a setup. What do the DIP switches on the top of the unit control?The DIP switches are used to configure specific functions of the module. This typically includes enabling or disabling Line Fault Detection (LFD) and selecting the mode for HART communication to prevent interference in multi-drop loops.
