Description

Allen-Bradley 1783-HMS8T4CGN Ethernet Switch (8-Port Managed)

Product Dimensions：

The Allen-Bradley 1783-HMS8T4CGN is a high-performance Stratix 5400 Industrial Managed Ethernet Switch. It is a Layer 2/Layer 3 capable switch designed to handle the high data demands of modern industrial automation environments, particularly those utilizing EtherNet/IP for integrated motion and safety.

Product Detailed Description

The 1783-HMS8T4CGN belongs to the Stratix 5400 series, which is a ruggedized switching platform built on Cisco technology. This specific model is a “Base” switch that features a combination of fast copper ports and gigabit uplink ports. It is designed to act as a distribution or access layer switch in complex network topologies like Device Level Ring (DLR) or star configurations.

Technical Parameters

Product Advantages

• Cisco Technology Integration: Utilizes the Cisco IOS® (Internetwork Operating System), providing a familiar environment for IT professionals while being optimized for industrial use.
• Network Redundancy: Supports Device Level Ring (DLR), Resilient Ethernet Protocol (REP), and Spanning Tree Protocol (STP), ensuring high network availability even if a cable is damaged.
• Premier Integration: Provides an Add-On Profile (AOP) for Studio 5000®, allowing automation engineers to configure and monitor the switch directly within their PLC project.
• Gigabit Performance: With all 12 ports supporting Gigabit speeds, it is ideal for high-bandwidth applications like high-definition video surveillance or complex motion control.
• Ruggedized Design: Built without fans to improve reliability and rated for extreme temperatures, making it suitable for factory floor environments.

Important Considerations (Precautions)

• SFP Compatibility: When using the combo ports with SFP modules, ensure the SFPs are Allen-Bradley (1783-SFP series) or Cisco compatible to avoid communication errors.
• SD Card Usage: The switch includes a slot for an SD card (1784-SD series). It is highly recommended to use this for automatic configuration backup to allow for fast replacement in case of hardware failure.
• Heat Dissipation: Although the switch is fanless, ensure there is adequate clearance around the cooling fins to prevent thermal throttling, especially when operating near the +70°C limit.
• Grounding: Proper industrial grounding of the DIN rail and the switch chassis is critical to protect against electromagnetic interference (EMI) and surges.

Product Applications

• High-Speed Motion Control: Providing the low-latency communication required for Kinetix® drives over EtherNet/IP.
• Core/Distribution Layer: Acting as a central hub in a manufacturing cell to aggregate data from smaller switches or I/O blocks.
• DLR Topologies: Serving as the “Ring Supervisor” for Device Level Ring networks to provide media redundancy.
• Smart Manufacturing (IIoT): Connecting factory floor sensors and controllers to enterprise-level SCADA and MES systems via secure Layer 3 routing.
