function
KFD2-STC5-EX2 Beijiafu analog input safety barrierThe product is suitable for inherently safe applications. This device can supply power to 2-wire smart transmitters located in hazardous areas. This device can convert analog input signals into isolated current values and transmit them to a safe area. Digital signals can be superimposed on input signals in hazardous or safe areas and can be transmitted bidirectionally. If the HART communication resistance in the circuit is too low, an internal resistance of 250 Ω between terminals 8, 9, 11, and 12 can be used.
The test interface used to connect the HART communicator is also integrated into the terminals of this device.
