Description
1. Unboxing & Physical Snapshot (Dynamic List)
- Model & Brand: Siemens 6DS1722-8BA (Teleperm Output Module)
- Physical Dimensions: Approximately 170mm x 140mm x 55mm (W x H x D)
- Estimated Shipping Weight: 1.8 kg (boxed with molded static-dissipative foam)
- What’s in the Box: 1x 6DS1722-8BA module in a factory-sealed metal-out ESD shielding bag, pluggable terminal blocks, gold-plated bus connectors, and original OEM compliance documentation.
2. Product Introduction (Structure B: Architecture Hook)
Sliding directly into the subrack backplane chassis, this output module coordinates actuation signals between central processing units and plant-level final control elements. The printed circuit card aligns smoothly along precision guide tracks before the rear edge fingers engage the bus sockets. (We always recommend checking the backplane guide pins for wear before sliding the card home to avoid slot misalignment.) Locking lever mechanisms secure the assembly tightly against continuous vibrational forces.

4. Global Compliance & Industry Certifications
Auditors require rigorous proof of design compliance before authorizing high-risk continuous process operations.
- Expected Certifications: CE Mark, UL/cUL Listed (Industrial Control Equipment), ATEX Directive (Zone 2 hazardous areas), and EAC compliance.
- Compliance Significance: The UL listing guarantees that internal creepage distances and dielectric isolation barriers prevent dangerous arc-over faults. (Class I Div 2 classifications protect against localized spark ignition in volatile chemical atmospheres.) Verify specific lot certifications with OEM documentation before closing out plant safety reviews.
5. Long-Term Storage & Asset Preservation Guide
Warehouse storage destroys unprotected electronics if humidity and electrostatic hazards go unmanaged. Keep this asset safe:
- Store the module sealed tightly inside its original metal-out anti-static (ESD) shielding bag to block atmospheric moisture and static discharge.
- Maintain warehouse relative humidity strictly below 60% to prevent oxidation on the gold-plated edge fingers and printed circuit traces.
- Lay the unit flat on static-dissipative foam pads to absorb structural building vibrations and prevent micro-fractures in the printed circuit board.
6. Physical Installation Prerequisites
Proper mechanical placement guarantees longevity and prevents localized overheating inside the cabinet enclosure.
- Convection Clearance: Leave at least 40mm of open space above and below the card chassis to permit proper vertical airflow.
- Grounding Protocol: Engage the subrack grounding clips securely to the metallic backplane rail using external tooth star washers to suppress electrical noise.
7. Buyer’s FAQ (Logistics & Compliance Focus)
Q: Which Harmonized System (HS) code applies to international customs clearance for the 6DS1722-8BA?
A: This output module typically clears under HS code 8538.90, but importers should confirm final classification with their broker according to local destination rulings.
Q: Does this surplus unit come with the latest factory firmware pre-installed?
A: New surplus hardware ships with the revision level stamped on the original box label; check your project engineering database to verify compatibility.
Q: How does the declared Country of Origin (COO) influence international shipping paperwork?
A: The COO—typically Germany for this manufacturing run—dictates preferential duty rates under international trade agreements, making a verified certificate of origin essential.
