KFD2-STC4-Ex2, SMART Transmitter Power Supply

SMART Transmitter Power Supply, KFD2-STC4-Ex2   2-channel isolated barrier 24 V DC supply (Power Rail) Input 2-wire SMART transmitters Output 0/4 mA ... 20 mA Terminals with test points Up to SIL 2 acc. to IEC/EN 61508 This isolated barrier is used for intrinsic safety applications. The device supplies 2-wire SMART transmitters in a hazardous area. It 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 safe area and are transferred bi-directionally. If the HART communication resistance in the loop is too low, the internal resistance of 250 Ω between terminals 8 and 9 can be used. Test sockets for the connection of HART communicators are integrated into the terminals of the device.
