Frequently Asked Questions
Q: How do I set the DIP switch on this safety barrier?
A: The DIP switches are typically located below the marking space on the front of the device (you may need to remove the transparent label cover). These switches are primarily used to configure input signal type, output characteristics, or fault alarm modes.
Q: What is the difference between it and KFD2-SOT2-EX1.LB?
A: Both KFD2-SOT3-Ex1.LB and KFD2-SOT2-Ex1.LB belong to the KFD2 series of isolated safety barriers from Pepperl+Fuchs (P+F) of Germany. They are essentially identical in basic parameters such as appearance, power supply, and explosion-proof safety rating. Their most significant difference lies in the number of channels and the resulting signal processing capabilities.
Q: What is the typical wiring diagram for its application circuit?
A: A typical application of this safety barrier is to safely transmit switching signals (such as proximity switches, reed switches, etc.) from a hazardous area (field) to a PLC or DCS system in a safe area (control room). Its wiring mainly consists of three parts; please contact me for detailed information.
