Product Description

The ANR10D-415 is a high-performance ER Bus Node Unit designed for the CENTUM VP and CENTUM CS 3000 Distributed Control Systems from Yokogawa Electric Corporation. It functions as a critical communication interface between the Field Control Unit (FCU) and remote I/O modules via the Extended Remote (ER) bus.

The “D” designation indicates a dual-redundant architecture, ensuring continuous process operation even if one communication path fails. This -415 variant is specifically intended for 100–120 V AC power environments and is engineered with enhanced noise immunity to maintain stable communication in electrically harsh industrial installations.

Technical Specifications

Application Context

The ANR10D-415 is typically deployed in large-scale industrial plants where I/O modules must be installed at significant distances from the central controller. It supports mixed installation of analog and digital I/O modules within a single node, providing a flexible and scalable remote I/O architecture for:

• Refinery and petrochemical complexes

• Chemical processing plants

• Power generation facilities

• Large DCS cabinet or marshalling room layouts

Technical FAQ

Does the ANR10D-415 support hot-swapping of I/O modules?
Yes. The ER node architecture allows individual I/O modules to be replaced while the ER bus remains active, provided the system is configured for online maintenance.

What is the maximum distance for the ER Bus connection?
ER Bus distance depends on the cable type used. With standard coaxial cable, distances up to approximately 185 meters can be achieved without repeaters.

Is the power supply redundant in this model?
Yes. The ANR10D-415 supports dual power supply modules, complementing its redundant communication design and maximizing overall system availability.
