Product questions
What types of input does the KFD2-STC5-Ex2 accept?
It has two channels for 4–20 mA analog signals from 2-wire or 3-wire SMART transmitters or 2-wire SMART current sources. Check the transmitter and loop parameters against the exact device data before selection.
Does the KFD2-STC5-Ex2 pass HART signals?
Yes. This barrier supports HART signal transmission alongside the analog current signal. Check the complete loop and communicator requirements before installation.
Can the outputs be used with sinking and sourcing control inputs?
Yes. The two-channel barrier supports current-sink and current-source output modes. In source mode the barrier powers the output loop; in sink mode the loop requires external power. Verify the control input and wiring against the manufacturer’s diagram.
What supply voltage and mounting does the KFD2-STC5-Ex2 require?
The supply range is 18–30 V DC, connected via the Power Rail or supply terminals. The housing mounts on a 35 mm DIN rail and uses screw terminals.
Is the KFD2-STC5-Ex2 suitable for hazardous-area circuits?
It is an isolated barrier intended for intrinsic safety applications. Suitability depends on the installation zone, field device, entity parameters and applicable documentation; verify the complete circuit and the exact unit and serial number before use.
