System compatibility

Designed for Yokogawa CENTUM VP and CENTUM CS3000 DCS FIO system,installed on ANR10 ER bus node unit,realize communication between FCS field control station and remote FIO I/O node,widely used in petrochemical,power,chemical refining process control.

Function

EB401-10 is ER bus master interface module for FIO remote I/O.It establishes ER bus high-speed link between FCS and remote I/O node,transmits analog,digital and pulse I/O data deterministically.Supports dual redundant bus configuration to guarantee continuous communication if single channel fails.Bus parameters can be configured via CENTUM VP engineering software.

Installation

Install on ANR10 node unit backplane slot,connect ER bus shielded cable or optical fiber,configure node address and redundancy parameters by CENTUM VP engineering software.Hot swap supported.

Interface

‑ER bus field communication port

‑Internal ESB bus backplane connector

‑LED indicators for run,bus link and fault status

Circuit feature

Galvanic isolation design for ER bus port,anti-electromagnetic interference,built-in bus self-diagnosis,deterministic real-time data transmission,suitable for long-distance distributed I/O deployment.

Feature

EB401-10 belongs to Yokogawa CENTUM VP FIO series ER bus master module.Suffix -10 is standard version.Common faults:bus cable poor contact,connector damage,bus communication chip failure.Confirm firmware version before replacement.

Diagnostic

Bus link loss,communication timeout or module hardware fault triggers alarm and upload diagnostic information to DCS HIS station.

Built‑in function

Realize ER bus communication between FCS and remote FIO I/O node,transfer I/O signals for distributed control system,used for industrial DCS spare replacement.

Product Brief

EB401-10 is Yokogawa CENTUM VP / CS3000 FIO ER bus master interface module,supports redundant bus and remote I/O connection.Check ANR10 node unit and system firmware compatibility before ordering.ESD anti-static protection required during installation.
