Yokogawa AVR10D-Q22021 Duplexed V net Router
The Yokogawa AVR10D-Q22021, also cataloged as the AVR10D Duplexed V net Router, operates as a dedicated hardware component for multi-network protocol bridging and real-time signal transmission between Vnet/IP and legacy V net domains within CENTUM VP control systems.

Process Network Bridging & Channel Isolation
The AVR10D-Q22021 establishes deterministic cross-domain routing between high-speed 100 Mbps Vnet/IP backbones and legacy 10 Mbps V net or VL net coax networks. Galvanic isolation and continuous channel diagnostics protect process control loops from network noise, voltage spikes, and ground loop interference. Built-in dual redundant circuitry automatically reroutes packet traffic upon detecting a cable break or transceiving hardware failure on the primary V net channel, maintaining continuous database synchronization across CENTUM VP Human Interface Stations (HIS) without packet drops or signal latency spikes.
Frequently Asked Questions
Q: How does the AVR10D-Q22021 manage media conversion between Vnet/IP and legacy coaxial networks?
A: The router performs real-time protocol conversion between the 100BASE-TX full-duplex Ethernet framing of Vnet/IP and the 10BASE-2 coaxial bus architecture of V net and VL net, routing packets across integrated dual-redundant processing channels.
Q: What power options are available for powering the AVR10D-Q22021 module?
A: The hardware supports dual-line or single-line power configurations operating at 100-120 VAC (80 VA), 220-240 VAC (110 VA), or 24 VDC (1.7 A).
Q: What physical cabling standards are required for the network interfaces on the AVR10D-Q22021?
A: The Vnet/IP port requires Category 5e or better shielded UTP cables terminated with RJ45 connectors up to 100 meters, while the V net and VL net connections require standard 50-ohm coaxial cables with BNC T-junction connectors.
Field Installation Guidelines
Mount the AVR10D-Q22021 into a standard 19-inch instrument rack using four M5 mounting screws along with the provided insulation bushes to isolate the chassis from rack ground loops. Connect an earth ground strap directly to the M4 ground screw terminal before applying system power. Fasten BNC T-junction connectors securely to the V net coaxial ports and ensure proper 50-ohm termination resistor blocks are installed at the physical endpoints of the coaxial segment. Route CAT5e Ethernet cables away from high-voltage AC mains lines and verify ambient operating temperatures inside the cabinet stay within 0 deg C to 55 deg C.
