• Dimensions: Approximately 85 mm × 50 mm × 35 mm (or 90 mm × 60 mm × 35 mm)
• Weight: 0.2 kg to 0.5 kg
• Certifications: IECEx, Explosion-proof Ex d IIC T6, ISA-S71.04 (G3)

3. Product Features

• High Reliability: Designed with dustproof, waterproof, shock-resistant (10 g), and vibration-resistant (0.5 g) capabilities to adapt to harsh industrial environments.
• Multi-Protocol Compatibility: In addition to Foundation Fieldbus H1, it supports DeviceNet, Profibus, EtherNet/IP, etc., facilitating system integration.
• Modular Expansion: Can be used as an analog expansion module to increase I/O channels, supporting various analog signals such as temperature, pressure, and flow.
• Easy Configuration: Parameter setting and monitoring are performed via DeltaV Control Studio software, with support for hot swapping and on-site diagnostics.
• Explosion-Proof Design: Complies with the Ex d IIC T6 explosion-proof rating, suitable for hazardous areas such as petroleum and chemical industries.

4. Structure and Composition

• Card Body: Features an aluminum alloy housing that provides IP66 protection.
• Power Module: Separates the local bus power supply circuit (12 V DC) from the field circuit (32 V DC).
• I/O Interfaces: Includes several analog input/output terminals (available options: 4-20 mA, 0-10 V, -10-10 V) and a communication port (H1 bus).
• Explosion-Proof Junction Box (for some models): Used for cable connection in hazardous areas, with Ex d protection.

5. Typical Application Areas

• Process Automation: Process control systems in industries such as petroleum, natural gas, chemicals, pharmaceuticals, food and beverages, and water treatment.
• HVAC and Cold Chain: Temperature control for refrigeration and freezing equipment.
• Industrial Heating and Cooling: Accurate monitoring and regulation of temperature, pressure, and flow.
• Mechanical and Equipment Monitoring: On-site data collection for injection molding machines, compressors, pump stations, etc.
• Hazardous Areas: The explosion-proof junction box is used for cable connection in flammable and explosive environments such as petroleum and chemical industries.

6. Installation and Maintenance Key Points

1. Pre-Installation Check: Confirm the model and complete accessories; verify the power supply voltage, wiring diagram, and fieldbus compatibility.
2. Installation Method: Supports DIN rail or wall-mounted installation; explosion-proof versions require the use of an explosion-proof junction box and compliance with IECEx installation specifications.
3. Wiring: Follow the manufacturer-provided wiring diagram to connect the local bus (12 V DC) and field circuit (32 V DC), ensuring the current per port does not exceed 12 mA.
4. Software Configuration: Use DeltaV Control Studio or the corresponding manufacturer’s configuration software to perform I/O mapping and communication parameter settings.
5. Commissioning: Conduct on-site signal calibration (for temperature, pressure, etc.), check communication status, and confirm the availability of alarm and diagnostic functions.
6. Maintenance: Regularly inspect the tightness of the power supply and junction box; clean the housing to prevent dust accumulation; conduct annual re-inspection of explosion-proof certification; update firmware or driver software to maintain compatibility.
7. Troubleshooting: Use the diagnostic LEDs on the card or the fault logs of the DeltaV system to locate issues; replace the module or junction box if necessary.

Frequently Asked Questions (FAQs)

Q: Are you operating as a trading company or a manufacturer?
A: We are a trading company—this is our core business model.
Q: Do you keep inventory in-house, or do you need to source goods from other suppliers?
A: We maintain a substantial inventory for immediate sale, and we also have our own dedicated warehouse to store these goods.
Q: Can you guarantee 100% original and brand-new products?
A: Without a doubt. You won’t find any plagiarized, counterfeit, or refurbished items here—only 100% original products.
Q: Do you offer outdated products, even those that are quite old?
A: Here’s how we handle it: If a new model is available to replace the old one, we’ll actively recommend the new model to you. If replacement isn’t feasible, we’ll assist with inspecting the old product to confirm it’s in good working condition. For any other usage-related conditions, we’ll always be transparent and share the full truth.
Q: How long is your typical lead time for delivery?
A: The lead time varies by stock status and order size: For in-stock goods, it usually takes 2-3 working days. For large-volume orders, you can expect a lead time of 5-7 working days after we receive your payment. For non-regular products (i.e., items not in our standard inventory), the ordering and delivery process typically takes 3-4 weeks or 6-8 weeks.
