Process Control Connectivity Features

The AVR10D-Q22020 supports channel-to-channel isolation to prevent propagation of network noise across redundant domains. It allows deterministic routing of 100Base-TX and legacy V net traffic, with electrical isolation between Vnet/IP ports and coaxial networks. Built-in failover mechanisms in dual-redundant power and communication modules ensure uninterrupted operation during hardware faults. The unit also maintains compatibility with standard 4-20 mA HART loops and FOUNDATION Fieldbus/Profibus PA connections through connected controllers, preserving signal integrity across control layers.

Frequently Asked Questions

Q: VnA: Can the AVR10D-Q22020 modules be hot-swapped without network interruption?
A: Yes, dual-redundant modules support bumpless hot-swap; the secondary module takes over instantaneously with sub-millisecond failover.

Q: VnA: What is the maximum distance supported for Vnet/IP connections?
A: Standard 100Base-TX cabling is supported up to 100 m to a Layer 2 switch; no signal repeaters are required within this range.

Q: VnA: Does firmware upgrade require shutdown of V net communication?
A: Firmware updates can be applied to one module while the redundant module maintains network operation, ensuring no interruption.

Field Installation Guidelines

1. Mount the router on a 19-inch rack using 4 x M5 screws. Ensure the unit is level to prevent strain on connectors.
2. Connect power lines to dual-redundant inputs via M4 screw terminals. Verify phase and ground continuity before energizing.
3. Attach Vnet/IP and V net coaxial cables to the respective RJ45 and BNC connectors. Ensure correct termination on coaxial lines to prevent reflections.
4. Use separate grounding for chassis and signal shields to minimize crosstalk. Maintain at least 10 mm separation from high-power cables.
5. Confirm all redundant modules are seated and operational via the front panel LED indicators before commissioning.
6. Avoid bending coaxial lines below 50 mm radius; secure cables to prevent mechanical stress.
7. Contact output terminals can be wired to local alarm panels; ensure voltage ratings are compatible.
