Product Overview

The Allen Bradley 1783-BMS20CDP belongs to the rugged Stratix 2000 series of industrial unmanaged Ethernet switches. Featuring 20 high-density, auto-negotiating 10/100 Mbps copper ports, this device enables immediate network expansion across manufacturing floors and utility automation systems without demanding complex IT configurations. The compact, plug-and-play architecture provides a 4.8 Gbps switching capacity to maintain seamless data traffic between local controllers, HMIs, and peripheral field hardware.

We guarantee this product is 100% Brand New, completely original, and directly source-verified for immediate integration into your high-availability industrial control layouts.

Technical Specifications

Engineering Advantages

• Eliminates Configuration Overhead: The unmanaged architecture functions immediately out of the box. Commissioning teams require zero specialized network engineering software, saving installation labor during sudden system expansions or hardware replacements.

• Maximizes Dense Panel Space: Packing 20 full RJ45 copper interfaces into a compact 45 mm wide form-factor reduces total footprint requirements. This high-density port allocation allows panel builders to squeeze more network connections into tightly spaced control cabinets.

• Withstands Extreme Field Temperatures: Heavy-duty internal components allow continuous full-load operational performance from -40 up to +75 degrees C. This broad operational tolerance eliminates the need for expensive enclosure cooling fans or heating elements in remote outdoor field locations.

• Ensures Low-Latency Data Delivery: An ultra-low internal packet processing delay of less than 5 microseconds ensures immediate, predictable data transfer. This high-speed performance prevents communication jitter between critical real-time automation devices like PLCs and remote I/O blocks.

FAQs

• Does the 1783-BMS20CDP support advanced industrial protocols like EtherNet/IP prioritization via Quality of Service (QoS)?

  As an unmanaged switch, this model lacks manual software management tools for advanced traffic shaping, VLAN segmenting, or diagnostic logging. It transmits all standard Ethernet traffic neutrally on a first-come, first-served basis. If your architecture demands explicit IGMP snooping or strict QoS management for complex motion control profiles, consider stepping up to a managed platform like the Stratix 5700 series.

• What are the wiring recommendations for the DC power input block?

  Connect a stable 12 to 48 VDC industrial power source to the removable terminal plug located on the unit chassis. Use standard copper wiring rated for the environment and ensure proper ground termination to the chassis grounding screw to protect the internal data lines from industrial electromagnetic noise.

• Can I mix 10 Mbps and 100 Mbps devices across the 20 available copper ports?

  Yes. Each individual RJ45 interface contains auto-sensing circuitry that automatically negotiates connection speeds and duplex modes (half or full) to match the connected target device, optimizing communication performance automatically.
