FAQ

Q1: What is the impedance of the YCB301-C200 cable and why is it important?

A1: The impedance is 120 Ω, which is critical to minimize reflection and ensure proper signal transmission in differential communication systems like ESB.

Q2: How does the double-shielding design enhance communication reliability?

A2: The aluminum foil and braided shield block external electromagnetic interference, reducing data errors and ensuring clean transmission.

Q3: Can the cable be used for both horizontal and vertical installations?

A3: Yes, its flexible construction allows for both horizontal and vertical routing without compromising performance.

Q4: Is this cable compatible with non-Yokogawa communication systems?

A4: While optimized for ESB bus, it can technically support other RS-485 or similar balanced communication systems with matching impedance.

Q5: What is the maximum data transmission speed supported by this cable?

A5: It supports ESB communication speeds up to 12 Mbps without degradation.

Q6: How is the cable protected against signal loss over long distances?

A6: By maintaining proper impedance and shielding, the cable reduces attenuation and reflection, allowing stable transmission over 200 m.

Q7: What type of insulation is used in the YCB301-C200 cable?

A7: Flame-retardant PVC or LSZH insulation is used depending on environmental requirements.

Q8: Does the cable require termination resistors?

A8: Yes, standard ESB bus configurations require termination resistors at both ends of the bus to prevent reflection.

Q9: Can the YCB301-C200 operate in outdoor environments?

A9: While it is primarily designed for indoor industrial use, with proper protection (trays, conduits), it can be deployed outdoors.

Q10: How does this cable differ from YCB301-C100 or C300 versions?

A10: The main difference lies in standard length and weight; performance characteristics remain consistent across the series.
