Interface and Engineering Summary
The YCB141-M001 is a high-integrity coaxial communication cable designed for Yokogawa Vnet network systems. It supports 10BASE-2 physical layer communication, providing reliable connections between Field Control Stations (FCS), Human Interface Stations (HIS), and bus couplers such as the VC401 module.
The cable is optimized for low signal attenuation and strong EMI/RFI resistance, ensuring stable deterministic communication within CENTUM distributed control systems. The 1-meter (M001) length is mainly used for intra-cabinet wiring and short-distance module interconnection.

Technical FAQ
Is it compatible with Ethernet?
No. The YCB141-M001 is designed for Yokogawa Vnet 10BASE-2 coaxial networks. Vnet/IP systems require Ethernet cabling such as CAT5e or CAT6.
Can the cable be extended with adapters?
Not recommended. Using the correct suffix-length cable is important to maintain the required 50 Ω impedance for signal integrity.
What is the difference between YCB141 and YCB147?
YCB141 is used for standard Vnet coaxial communication, while YCB147 is typically used for other bus types or enhanced durability applications.
