FAQ

 

Q: Can you build PLC cabinets according to our provided EPLAN schematics?

A: Yes. We accept EPLAN Electric P8 and AutoCAD Electrical project files. Our engineering team reviews cable schedules, terminal assignments, and BOMs prior to production to confirm component availability and layout compliance.

Q: Which PLC brands do you integrate into your panels?

A: We regularly integrate Siemens (S7-1200, S7-1500, ET200SP), Allen-Bradley (Micro800, CompactLogix), Schneider Electric, Mitsubishi, and Omron. If required, clients can also supply free-issue PLCs for us to wire and mount.

Q: What wire marking standards do you use?

A: All internal conductors are identified at both ends using machine-printed heat-shrink sleeves or clip-on ferrules. Wire numbering strictly corresponds to the line numbers in the project electrical schematics.

Q: How do you handle thermal calculations for enclosed PLC hardware?

A: We calculate heat dissipation based on the total thermal losses of internal components (PLC modules, power supplies, VFDs/drives, transformers) under max ambient operating temperatures, then size filter fans or panel air conditioners accordingly.

Q: What testing is conducted prior to delivery?

A: Every panel receives 100% continuity testing, insulation resistance testing, and a functional no-load power-up check. A signed Factory Acceptance Test (FAT) record is included with the shipment.

Q: What are your standard production lead times?

A: Standard lead time for customized panels is 3 to 4 weeks after engineering drawing approval, depending on component lead times from specified brands (e.g., specialized PLC modules or air conditioners).
