• Power Interface: Equipped with LocalBus power supply terminals (12 V DC) and overcurrent protection.
• Shield Bar: Located on the back of the module to reduce electromagnetic interference.
• Mounting Holes: Complies with DIN-rail standards for easy cabinet installation.

5. Typical Application Fields

• Large-scale power plants (power generation, combined heat and power)
• Petroleum and chemical industry (process control, pipeline monitoring)
• Pharmaceutical and biopharmaceutical industry (clean process control)
• Marine and offshore platforms (distributed control)
• Robotics and automated production lines (high-speed I/O interaction)
• Other industrial automation systems (e.g., iron and steel, papermaking, food and beverage)

6. Installation and Maintenance Guidelines

Step 1: Preparations

Step 2: Mechanical Installation

Step 3: Electrical Wiring

Step 4: Configuration

Step 5: Function Verification

Step 6: Regular Maintenance

• Check the tightness of terminals and the integrity of the shield bar every 6-12 months.
• Remove dust and check the grounding resistance.
• If an abnormality is found, replace the module using the hot-swapping function to avoid system shutdown.

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Q: Do you offer outdated products, even those that are quite old?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.
