FAQ
1. What type of signals can the KS9-20 transmit?
It supports both analog (mA, V) and digital low-voltage control signals.
2. How does the shielding improve signal reliability?
The foil shield and drain wire reduce electromagnetic interference and prevent signal distortion.
3. What is the rated voltage of the KS9-20?
It is rated for a maximum of 300 V.
4. Can this cable be directly buried underground?
It is not designed for direct burial; additional protective conduit is required.
5. What is the recommended minimum bend radius?
The cable should not be bent tighter than 10 times its diameter.
6. Can KS9-20 be used in hazardous areas?
Yes, if installed in accordance with local hazardous area wiring standards and using approved glands.
7. Does the cable support twisted pairs or parallel conductors?
It uses parallel insulated conductors with overall shielding, not twisted pairs.
8. How many conductors are inside the KS9-20 cable?
It contains 5 copper conductors.
9. Is the cable resistant to chemicals commonly found in industrial plants?
Yes, the PVC sheath offers resistance to oils, solvents, and mild acids.
10. Can this cable be used with non-Yokogawa equipment?
Yes, provided voltage, current, and shielding requirements are compatible.
