Yokogawa ANB10D-421 Node Unit for Dual-Redundant ESB Bus

Description

The ANB10D-421 is a high-availability node unit developed by Yokogawa for use in CENTUM VP and ProSafe-RS platforms. It serves as a communication bridge between field I/O signals and Field Control Units (FCUs), while also supplying power to connected I/O modules. Its dual-redundant ESB bus architecture ensures fault-tolerant performance in mission-critical environments.
