Frequently Asked Questions (KFD2-STC5-EX2)
The device supports 2-wire and 3-wire SMART transmitters as well as 2-wire SMART current sources. It provides sufficient voltage (≥16 V at 20 mA) to power most industrial SMART transmitters in hazardous areas.
Yes. Digital HART signals can be superimposed on the 4-20 mA input signal in both hazardous and safe areas, with bidirectional transfer. The integrated test sockets allow direct connection of a HART communicator without breaking the loop.
The internal 250 Ω resistor (at terminals 9 and 12) can be used as a load resistor for the current output. This is particularly useful when the HART communication resistance in the control circuit is too low.
The device is certified for SIL 2 (SC 3) according to IEC/EN 61508, making it suitable for safety instrumented systems (SIS) requiring high reliability.
Yes – HKXYTECH ships worldwide. Typical delivery times: North America & Europe: 3-5 business days; Asia & Middle East: 2-4 business days; South America & Africa: 5-7 business days.
