Product Description

The AVR10D-A22040 is a high-availability Duplexed Vnet/IP Interface Unit for the CENTUM VP control system. Serving as a communication hub, it connects Field Control Units (FCUs), Human Interface Stations (HIS), and other nodes to the Vnet/IP real-time network. Its duplexed architecture and dual-redundant power modules ensure continuous operation and eliminate single points of failure, making it ideal for critical industrial facilities such as refineries, chemical plants, and utility-scale power stations. The A22040 variant is specifically configured for high-voltage operation (220–240 V AC).

Technical Specifications

Industrial Application Scenarios

The AVR10D-A22040 is ideal for real-time, high-availability control networks in industries such as:

• Petrochemical and Refining

• Power Generation Plants

• Large-scale Water/Wastewater Treatment Facilities

Its duplexed Vnet/IP design ensures deterministic, secure, and reliable data transmission between distributed control nodes, eliminating downtime risks associated with single points of failure. It integrates seamlessly with CENTUM VP FCUs and HIS workstations to provide robust network connectivity across plant-wide automation architectures.

Technical FAQs

1. What is the difference between Vnet and Vnet/IP?
Vnet/IP is the Ethernet-based evolution of legacy Vnet, offering higher bandwidth, compatibility with standard network switches, and deterministic real-time communication. The AVR10D-A22040 is specifically designed for Vnet/IP networks.

2. Can this unit operate on 110 V AC?
No. The A22040 model is rated only for 220–240 V AC. For installations requiring 110 V AC, a different power supply suffix must be selected.

3. Is the duplexed design hot-swappable?
Yes. The dual-redundant architecture allows one network path or power module to fail without interrupting network communication, ensuring continuous operation of the control system.
