KFD2-STC4-Ex2 SMART transmitter power supply - Features:

• 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 61508

Function:

• 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.
