Yokogawa ANR10D-420/ATDOC/NDEL ER Bus Unit

The Yokogawa ANR10D-420/ATDOC/NDEL ER Bus Unit is an integral component of Yokogawa’s industrial automation and safety systems, particularly tailored for high-performance and reliable communication in demanding environments. It forms part of the ProSafe-RS (SIS – Safety Instrumented System) architecture, facilitating robust and secure communication between I/O units and controllers via the ER Bus (Extension Redundant Bus).

Designed with flexibility and system integrity in mind, this ER Bus Unit ensures that safety-critical applications such as Emergency Shutdown Systems (ESD), Burner Management Systems (BMS), and Fire & Gas Systems (FGS) maintain uninterrupted data exchange. Its configuration supports redundancy, fault tolerance, and easy scalability, all essential for critical plant operations in industries such as oil and gas, petrochemical, and power generation.
