Product Introduction

Architecture hook: The CX2420 is a Yokogawa DAQSTATION CX2000 control and measurement station, combining data acquisition with embedded control functions in a panel-mounted instrument. The specifically provides four internal control loops and 20 measurement channels, making the exact suffix configuration important when matching a replacement.

The supplied 3-2-2 configuration is not merely a cosmetic suffix. It identifies the ATA flash storage option, Ethernet plus RS-422A/485 communications, and English display language. Because CX2000 variants can differ in storage media, serial interface, control-loop count, and option boards, a base-model match without the complete suffix can result in an incorrect spare.

Yokogawa’s original documentation confirms the model architecture and suffix coding. The later replacement guide specifically maps configurations into the newer SMARTDAC+ GX20 architecture, confirming that belongs to the legacy platform.

? Global Compliance & Industry Certifications

For this legacy Yokogawa measurement/control station, compliance should be tied to the exact hardware revision and installed option configuration.

• CE Mark: Verify the applicable declaration for the exact configuration.
• UL/cUL: Verify the rating/certification information on the unit and original Yokogawa documentation before making a North American compliance claim.
• ATEX / IECEx: Do not assume hazardous-area certification. The should not be represented as ATEX/IECEx equipment without documentation covering the exact configuration.
• Marine approvals: DNV or equivalent marine certification must be verified separately; do not infer it from the product family.
• EMC: Verify the applicable conformity documentation and installation requirements, including grounding, panel installation, and signal wiring.

The certification record matters because the is an integrated measurement/control station rather than a simple passive recorder. Its communications, control outputs, measurement inputs, and power supply all form part of the installed system’s compliance boundary.

Verify specific lot certifications with OEM.

? Long-Term Storage & Asset Preservation Guide

• Protect the ATA flash media. Preserve the original memory card and its identification with the unit. Do not substitute a random CompactFlash/ATA-compatible card when the stored configuration is operationally significant.
• Control humidity and condensation. Keep the unit in its original protective packaging in a clean, dry warehouse, preferably below 60% RH. Avoid repeated temperature excursions that can produce condensation around the display, connectors, and internal electronics.
• Preserve the front-panel assembly. The display, keys, bezel, and panel-mount hardware should be protected from pressure and impact during storage. Do not stack heavy equipment on top of the .

Before energizing a long-stored , inspect the power connector, communication ports, memory-card interface, display, cooling openings, and internal signs of corrosion. Record the firmware and configuration revision before replacing an operating unit.

Physical Installation Prerequisites

• Install using the specified panel-mounting brackets and the applicable mechanical cutout dimensions.
• Provide adequate rear clearance for power, Ethernet, RS-422A/485, measurement, and control wiring; do not use a generic 50 mm clearance in place of the OEM panel drawing.
• Ensure that the ventilation openings are not obstructed by cabinet structure or cable bundles.
• Establish the required protective grounding connection before energization.
• Keep measurement wiring separated from high-current switching and motor wiring where required by the installation design.
• Confirm the RS-422A/485 termination, polarity, and communication parameters before connecting the serial network.
• Verify the installed ATA flash media and configuration before transferring production operation to the replacement.
• Because this unit contains control outputs as well as measurement circuitry, confirm all output states and interlocks before enabling the replacement in an operating process.

Buyer’s FAQ

Q: What HS Tariff Code should be used for -3-2-2?
A: Classify it according to its actual function as a data acquisition/control station and the tariff rules of the importing country. Do not classify it simply as a generic recorder or computer because the incorporates measurement and control functions.

Q: Does the Country of Origin follow Yokogawa’s corporate location?
A: No. COO must be supported by the actual manufacturing documentation for the specific unit. Record the nameplate origin, supplier declaration, and commercial-invoice information consistently before making any preferential-origin claim.

Q: How should this 7.5 kg unit be packaged for international shipment?
A: Protect the front display and controls from compression, immobilize the chassis inside the carton, and use sufficient cushioning around the panel-mount hardware and connectors. For a discontinued instrument, shipping insurance should be considered based on replacement value and operational criticality rather than weight alone.

Q: Does -3-2-2 include the latest firmware?
A: Do not assume it does. Firmware/configuration should be read and recorded from the actual unit before commissioning. The platform is discontinued, and Yokogawa’s replacement documentation maps configurations to newer GX20 hardware; this makes configuration capture especially important when maintaining a legacy installation.
