Type KFD2-STC4-Ex1 - Isolated barrier
For hazardous area applications, HART® capable
Machine building and plant construction
1-channel isolated barrier for intrinsically safe pressure and temperature measuring instruments
DC 24 V supply
SIL 2 per IEC 61508
When using pressure and temperature measuring instruments in hazardous area applications, an intrinsically safe isolated barrier is required for intrinsically safe measuring instruments.
This isolated barrier is suitable for use in combination with the models LH-20, IL-10, IS-20, IS-21, IS-3, IUT-10, IUT-11, IPT-10, DPT-10, T32.XS, T24 and T12.
The instrument supplies 2-wire and 3-wire SMART transmitters in hazardous areas and is also suitable for 2-wire SMART current sources.
When the HART® communication resistance in the control circuit is too low, the internal resistance of 250 ohms can be used between terminals 8 and 9.
The instrument terminals have integrated test connectors for the connection of HART® communicators.
