Product Details And Specifications

Allen-Bradley Stratix 2000 Series Technical Notes

The Allen-Bradley Stratix 2000 series (catalog prefix 1783-BMS) is Rockwell Automation's purpose-built line of unmanaged Industrial Ethernet switches, designed for deterministic, low-latency communication in plant-floor environments. Deployed across petrochemical complexes, nuclear power auxiliary systems, offshore oil platforms, and continuous-process refineries, the Stratix 2000 family provides plug-and-play Ethernet connectivity without requiring network configuration expertise. Its DIN-rail form factor, wide operating temperature range (0 °C to 60 °C), and 24 VDC power input make it a standard infrastructure component in ControlLogix, CompactLogix, and legacy PLC-5 architectures worldwide. The series is fully compliant with IEEE 802.3 and supports 10/100 Mbps auto-negotiation on all copper ports, with select models offering fiber uplinks for electrically noisy or long-distance segment runs.

The Evolution of Stratix 2000 Architecture

Rockwell Automation introduced the Stratix 2000 line as a successor to legacy Allen-Bradley Ethernet tap modules, consolidating multi-port switching into a single, compact DIN-rail unit. Early revisions (Series A) supported fixed copper-only configurations with 5- and 8-port counts. Subsequent Series B hardware introduced fiber SFP uplink options (suffix GL and GA), enabling segment isolation across large plant floors where copper runs exceeded 100 m limits or EMI interference was a concern.

Quality Control for the Stratix 2000 Range

Each 1783-BMS unit processed by DriveKNMS undergoes a structured verification protocol before dispatch:

• Power-on functional test: Unit powered at 24 VDC nominal; all port LEDs verified for correct link/activity indication.
• Port-by-port traffic test: Each RJ45 and fiber port subjected to bidirectional 100 Mbps traffic using a calibrated Ethernet test set; frame error rate must be 0% over a 60-second test window.
• Fiber optic power measurement: For GL/TL/GA/TGA variants, optical output power measured with a calibrated optical power meter; must fall within Rockwell-specified TX power range (typically -20 dBm to -14 dBm for multimode).
• Thermal soak: Units operated at 55 °C for 30 minutes to screen for marginal components that pass at ambient but fail under thermal load.
• Visual and mechanical inspection: DIN-rail clip, terminal block integrity, and PCB condition inspected under 10× magnification; any unit with cracked housing, corroded terminals, or damaged SFP cage is rejected.
• Firmware/hardware revision logging: Series letter and hardware revision recorded and disclosed to customer prior to shipment to prevent compatibility surprises in revision-sensitive installations.
