Level Radar LCR20 Accessories 17.2.2 Communication-Specific Accessories HART Modem For intrinsically safe HART communication with PACTware via the USB interface. HART Loop Converter KFD2-HLC-Ex1.D.** This isolated barrier is used for intrinsic safety applications. The device is a HART loop converter that provides power to transmitters or can be connected to existing HART loops in parallel. The devcie used to evaluate and convert dynamic HART process variables to analog current signals or limit values.
Level Radar LCR20 Accessories 17.2.4 System Components KFD2-STC5-Ex1 This isolated barrier is used for intrinsic safety applications. The device supplies 2-wire and 3-wire SMART transmitters, and can also be used with 2-wire SMART current sources. The device transfers the analog input signal to the safe area as an isolated current value. Digital signals may be superimposed on the input signal in the hazardous or non-hazardous area and are transferred bidirectionally.
