Product Description
The EB402 is an ER (Ethernet Remote) Bus Master Interface Module designed for Yokogawa CENTUM CS and ProSafe-RS systems. It provides a high-capacity communication bridge between Field Control Stations (FCS) and remote I/O devices, supporting deterministic, high-speed data transmission for up to 32 field devices per module.
With dual front-facing ESB bus ports, the EB402 supports redundant network loops or branched topologies, making it ideal for high-density, distributed process control environments. Its robust industrial construction ensures reliability in extended-distance installations, reducing local wiring complexity while maintaining precise signal integrity.

Product FAQ
Q: What is the significance of the dual front-facing ESB ports?
A: They allow connection of two separate ESB bus branches or the creation of a redundant loop, enhancing network flexibility and reliability.
Q: Can the EB402 be used with CENTUM VP systems?
A: It is primarily designed for CENTUM CS and ProSafe-RS. Compatibility with CENTUM VP depends on the FCS model; it can often serve as a replacement for legacy infrastructure in hybrid systems.
