Technical Specifications

Industrial Network Optimization and Deterministic Velocity

The module incorporates dedicated hardware execution for EtherNet/IP deterministic networks, bypassing traditional software-layer bottlenecks on the backplane bus communication velocity licenses. This design ensures stable I/O density scaling during multi-node periodic data exchange. Firmware flash compatibility protocols embedded in the module protect against timing jitter during parallel master execution on the CEX bus, stabilizing high-speed industrial control performance when deployed alongside high-integrity safety loops.

Logistics Packaging Details

• 1 x ABB CI873 3BSE056899R1 Communication Module

• 1 x Product Certification and Factory Test Slip

• 1 x ESD Protective Shielding Bag

Field Deployment and Grounding Protocol

• CEX Bus Physical Attachment

  Mount the unit onto the standard CEX bus rail assembly. Secure the structural locking tabs to prevent unintended physical separation during high-vibration events.

• Shielded Ethernet Cable Routing

  Utilize category 5e or higher shielded twisted pair (STP) cabling terminated with robust metal-shielded RJ-45 plugs. Route the data lines away from high-voltage AC power tracks.

• Hazardous Area Wiring Controls

  When deployed in Class 1, Zone 2 environments, isolate all connection points until the local atmosphere is verified as completely non-hazardous.

Frequently Asked Questions

• Does this interface module support structural hot-swapping during active controller operation?

  Yes, the hardware supports hot-swap execution, allowing the module to be removed or replaced without stopping the remaining active CEX bus communication units.

• What is the threshold limit for maximum module deployment on a single CEX bus string?

  The system architecture restricts installation to a maximum limit of 12 communication interface units across the local CEX expansion bus layout.

• Can this module be applied directly within High Integrity (HI) safety-related controller applications?

  Yes, the unit is certified as safe for operational co-existence and functional use together with ABB High Integrity Controller systems.

• What physical connector type is utilized for the primary network uplink interface?

  The front-facing network panel contains one standard 8-pin RJ-45 female receptacle optimized for industrial Ethernet cabling.

• How is line redundancy handled across the physical network medium for this model?

  This specific hardware design provides no built-in line redundancy features; network fault tolerance must be achieved through module redundancy pairs.

• What specific structural environment limits apply to chemical gas protection?

  The internal circuit board assemblies features a conformal coating that is G3 compliant to ISA 71.04 standards for harsh atmospheres.

• What are the specific power supply requirements drawn directly from the host system?

  The unit exhibits a typical internal current consumption profile of 160 mA measured at a nominal supply voltage of 24 VDC.

• What steps must be followed to ensure compliance with cULus Class 1 Zone 2 hazardous certifications?

  The module must be enclosed within an IP54 or better tool-secured cabinet structure to avoid mechanical impacts and prevent spark hazards.
