Product Introduction & Supply Chain Strategy
The Yokogawa AVR10D-Q22020 is a duplexed network router designed for CENTUM CS 3000 and CENTUM VP Distributed Control Systems (DCS). It provides high-speed, fault-tolerant bridging between legacy 10 Mbps dual-redundant coaxial V net segments and modern 100 Mbps Ethernet-based Vnet/IP control networks. Equipped with fully redundant communication hardware and dual 220–240 V AC power supplies, this module guarantees continuous data transfer between Human Interface Stations (HIS) and Field Control Stations (FCS).
This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. Refurbished DCS routers present serious risks of degraded power supply capacitors and weakened BNC driver circuits that cosmetic cleaning cannot hide. In continuous chemical or power processing plants, an unexpected router failure can cause domain-wide loss of view, leading to emergency shutdowns with secondary costs vastly exceeding the initial purchase price. Securing factory-sealed New Surplus inventory preserves your Total Cost of Ownership (TCO), provides an operational lifespan of 10 to 15 years, and secures a reliable hot-standby spare for critical legacy infrastructure.

Installation & Configuration Guide
1.Pre-Installation Setup and Safety:LOTO & Static Controls.
Verify the station power is locked out/tagged out (LOTO). Attach a grounded ESD wrist strap before opening cabinet doors. Prepare the M5 mounting screws and insulating bushes supplied with the router chassis. Confirm incoming supply voltage matches the 220–240 V AC specification.
2.Removing the Legacy Hardware:Label BNC & Power Lines.
Carefully label all coaxial V net cables (Bus 1 and Bus 2) and Vnet/IP UTP cables. Disconnect the M4 power terminals on the rear panel. Unscrew the 19-inch rack-mount screws, ensuring the chassis weight (5.8 kg) is fully supported during extraction to avoid damaging adjacent rack modules.
3.Rack Installation and Wiring:Insulation & Physical Seating.
Position the AVR10D-Q22020 into the 19-inch rack frame using the provided insulation bushes to isolate ground noise. Reconnect the dual 220–240 V AC power lines to the M4 screw terminals. Torque the BNC coaxial T-junction connectors securely onto the V net ports and click the RJ-45 CAT5e cable into the Vnet/IP port.
4.Power-On Verification:Dual-Power Diagnostics.
Energize Power Supply Line 1 and Line 2 independently. Confirm that both power module status LEDs show healthy green indications. Verify on the CENTUM System View graphics that network communication establishes across both redundant paths without raising system diagnostic alarms.
Firmware/Software Versions & Upgrade Notes
- System Integration: Fully compatible with Yokogawa CENTUM VP, CENTUM CS 3000, and CENTUM CS 1000 architectures.
- Network Parameters: Requires matching domain number and station number configuration set via hardware switches/system software prior to commissioning.
- Firmware Consistency: When swapping routers in a dual-redundant network pair, ensure the hardware revision and internal firmware match existing domain routers. Running mismatched firmware revisions across V net bridging routers can lead to delayed frame handshakes or protocol synchronization failures.
Frequently Asked Questions (FAQ)
Q: Is this AVR10D-Q22020 unit brand new or refurbished?
A: This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. It retains original factory specifications, zero pin wear, and clean electrical history.
Q: What do the suffix codes “Q22020” mean on this Yokogawa model?
A: Breakdown of the suffix structure:
- -Q2: Dual-Redundant V net interface (10BASE-2 BNC)
- 2: Dual Power Supply modules
- 0: Standard placeholder code
- 2: 220–240 V AC power input
- 0: Basic type standard specifications
Q: Why is New Surplus priced higher than refurbished options on the secondary market?
A: New Surplus reflects the cost of sourcing untouched, factory-stored DCS components globally. While refurbished units are 20–30% cheaper, they carry hidden component degradation that frequently causes catastrophic plant trips. Paying for New Surplus buys guaranteed operational integrity, full unit lifespan, and complete peace of mind.
Q: Can I hot-swap this router while the CENTUM system is online?
A: While the duplexed architecture allows for redundant path takeover, power and signal connections must be handled strictly according to Yokogawa engineering guidelines. Disconnecting both power or network paths simultaneously will interrupt cross-domain control communications.
Q: What documentation and warranty support are provided with this router?
A: Units undergo full physical, ground continuity, and power-on quality verification. Every order includes a complete 1-year functional replacement warranty and anti-static packaging protection.
