SMART Transmitter Power Supply KFD2-STC4 -Ex1. Features Assembly 1-channel isolated barrier 24 V DC Supply ( Power Rail). Front view Input 2-wire and 3-wire SMART transmitters and 2-wire Removable terminals blue SMART current sources Output 0/4 mA .. 20 mA. Terminals with test points 1 2 3. Up to SIL2 acc. to IEC 61508 4 5 6. KFD2-STC4 -Ex1. Function LED green: Power Supply This isolated barrier is used for intrinsic safety applications. PWR. The device supplies 2-wire and 3-wire SMART transmitters in a hazardous area, and can also be used with 2-wire SMART . current sources. It transfers the analog input signal to the safe area as an 7 8 9. 10 11 12. isolated current value. 13 14 15. Digital signals may be superimposed on the input signal in the Removable terminals hazardous or safe area and are transferred bi-directionally. green If the HART communication resistance in the loop is too low, the internal resistance of 250 between terminals 8 and 9.
