It features 20 total ports, providing a scalable solution for complex machine-level networks and plant-wide integrations. This switch utilizes Cisco technology to deliver secure, resilient communication while maintaining seamless compatibility with the Rockwell Automation Integrated Architecture. We supply this unit as 100% Brand New and factory-original, ensuring your network maintains maximum uptime and peak data throughput.

Technical Specifications

The 1783-BMS20CA provides robust electrical isolation and flexible power options for demanding factory environments.

Engineering Advantages

• High-Density Connectivity: The 20-port configuration eliminates the need for multiple daisy-chained switches. This reduces network latency and simplifies cable management in high-density control cabinets.

• Comprehensive Signal Isolation: This switch features 50V continuous isolation between DC power ports, Ethernet ports, and alarm ports. This protection prevents ground loops and shields sensitive network traffic from industrial electrical noise and power surges.

• Cisco-Powered Logic: By incorporating Cisco IOS, the 1783-BMS20CA offers advanced management features including VLANs, QoS for EtherNet/IP prioritization, and robust security protocols to protect against unauthorized network access.

• Rapid Hardware Recovery: The module supports the 1784-SD1 memory card. This allows engineers to store the entire switch configuration externally. In the event of hardware damage, a technician simply swaps the SD card into a new unit to restore full functionality without manual reprogramming.

• Flexible Media Support: Integrated SFP slots allow for easy transition between copper and fiber-optic media. This enables long-distance communication and provides immunity to electromagnetic interference (EMI) in high-voltage areas.

FAQs

• Does the 1783-BMS20CA arrive in original factory packaging?

  Yes. We supply only 100% Brand New units in the original Allen-Bradley box with factory seals. We do not sell used or refurbished hardware.

• What type of cabling does this switch require for Ethernet connections?

  The switch utilizes standard RJ45 connectors. You must use at least Category 5e (2- or 4-pair) cable according to TIA 568-B.1 or Category 5 cable according to ISO/IEC 24702 to ensure reliable data transmission.

• How do I properly ground the unit?

  You must use a minimum of 4.0 mm² (12 AWG) stranded copper wire for the ground connection. Tighten the ground terminals to a maximum torque of 0.96 N•m (8.5 lb•in) to ensure a secure path for electrical noise dissipation.

• Can the switch trigger an external alarm during a port failure?

  Yes. The integrated alarm relay (rated 1A @ 30V DC) allows the switch to trigger external signaling devices or PLC inputs if it detects a power loss or a specific port link failure. Tighten the alarm connectors to 0.23 N•m (2.0 lb•in) during installation.
