- Physical Dimensions: Compact modular industrial card layout (approx. 160 mm x 160 mm x 120 mm packaged profile).
- Estimated Shipping Weight: 0.80 kg (Including anti-static moisture-barrier packaging and custom logistics carton).
- What’s in the Box: KJ2221X1-BA1 repeater printed circuit board assembly featuring dual network ports, front diagnostic LED status indicators, gold-plated backplane interface pins, and compliance documentation. (Note: The corresponding KJ2221X1-EA1 SIS Net Repeater Carrier is ordered separately).
2. Product Introduction
Designed to bridge physical distance constraints across sprawling plant layouts, this specialized network repeater extends and regenerates communication signals within DeltaV SIS safety mesh architectures.
Mounted inside safety instrumented system node cabinets, the hardware stabilizes data exchange between remote logic solvers and safety controllers. (Instrumentation reliability teams depend on this specific repeater layer to prevent packet attenuation and maintain deterministic loop response across high-integrity safety networks.)

4. Global Compliance & Industry Certifications
Safety auditors verifying plant emergency shutdown networks require strict proof of compliance for communication backbone hardware.
- Expected Certifications: CE Mark, RoHS environmental alignment, IEC 61508 safety loop compatibility, and hazardous location ratings (such as non-incendive Class I, Div 2 approvals when installed in certified enclosures).
- Safety Relevance: High electrical isolation between network segments prevents common-mode noise propagation and ground loops from disrupting safety-critical message passing between distributed logic solvers.
- Audit Directive: Verify specific lot certifications with OEM. Manufacturing batch numbers and revision tags must cross-reference cleanly with the plant’s safety validation files.
5. Long-Term Storage & Asset Preservation Guide
Communication repeaters and network interface cards kept in warehouse reserve stock degrade silently if environmental baselines are neglected.
- ESD Protection Integrity: Keep the circuit board sealed inside its original metallized anti-static shielding bag to protect static-sensitive transceivers from electrostatic discharge.
- Climate Management: Maintain warehouse storage relative humidity strictly below 60% non-condensing to prevent micro-oxidation on gold-plated backplane edge fingers.
- Pin Protection: Avoid placing unboxed modules on conductive or abrasive surfaces to prevent physical bending of the delicate multi-pin connectors on the rear base.
6. Physical Installation Prerequisites
Proper physical positioning and mechanical carrier alignment are mandatory to maintain fault-tolerant safety network loops.
- Carrier Requirements: Install the repeater exclusively into its designated KJ2221X1-EA1 SIS Net Repeater Carrier slot to ensure secure mechanical locking and backplane power distribution.
- Hazardous Area Power Rule: Never insert or remove this module while system power or field power is energized in hazardous zones. Always isolate power feeds prior to physical handling.
- Cable Routing: Separate network communication cabling entirely from high-voltage motor power runs to prevent electromagnetic interference coupling into the repeater links.
7. Buyer’s FAQ (Logistics & Compliance Focus)
Q: What Harmonized System (HS) Tariff Code applies to global shipments of this network repeater?
A: Industrial process control communication cards and network repeaters clear under HS Code 8538.90 (Parts suitable for use solely or principally with control apparatus). Confirm exact sub-headings with your customs broker.
Q: Does importing this SIS network component require a Certificate of Origin (COO)?
A: Yes. Securing an authentic Certificate of Origin from your vendor verifies manufacturing traceability, which is mandatory for plant quality assurance and regulatory audit compliance.
Q: Are these replacement repeater modules shipped with pre-configured network node addresses?
A: Units ship with standard factory firmware baselines. Safety engineers must verify hardware jumper configurations and network routing parameters within the DeltaV engineering software before putting the segment online.
