Overview Manuals Specifications
 

Features:

  • IInterface Between Mark VIe/Mark VIeS Controllers and Industrial Ethernet Network
  • Combines 10/100Base‑TX Copper Ports with 100Base‑FX Fiber Uplink for Flexible Connectivity
  • Operates in Conjunction with I/O Modules and Real‑Time Automation Systems
The GE IS420ESWBH2A operates as an unmanaged industrial Ethernet/IONet switch, providing reliable network connectivity for all controllers, I/O modules, and monitoring devices within the system. It continuously manages data traffic between 10/100Base‑TX copper ports and 100Base‑FX fiber uplinks, ensuring stable and high‑speed communication across the network. While standard operation supports a single network path, the switch can be configured with redundant power inputs and multiple fiber connections to maintain uninterrupted communication in the event of a primary link or power failure. The IS420ESWBH2A incorporates industrial-grade construction and high environmental tolerance, offering improved reliability and signal integrity over previous switch models in harsh automation environments.

The GE IS420ESWBH2A provides essential network switching functions common to the entire automation system, and is a critical component of the communication path, directly affecting reliable data exchange between controllers, I/O modules, and monitoring devices. One or more IS420ESWBH2A switches may be required per network depending on the system size and redundancy requirements. The IS420ESWBH2A occupies a standard DIN-rail or rack-mounted position and is always installed to maintain proper alignment and connectivity within the industrial Ethernet network.

For dual‑link or redundant network applications, the GE IS420ESWBH2A may require a second switch installed to provide an alternate communication path. In addition to standard single‑switch operation, the redundant configuration supports automatic failover. The system continually monitors the status of both switches and their connections. If the primary switch or network path is detected to be non‑responsive or transmitting outside expected parameters, the system automatically transfers network traffic to the secondary switch and generates an event in the system log.

The IS420ESWBH2A ESWB ETHERNET SWITCH may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
It serves as a robust network communication module that facilitates reliable data exchange between controllers, I/O modules, and other critical subsystems within real‑time industrial control networks.

Designed to operate in demanding environments such as power plants, gas turbines, refineries, and heavy industrial facilities, the IS420ESWBH2A delivers high‑performance Ethernet switching with a combination of copper and fiber connectivity. The unit supports sixteen 10/100Base‑TX RJ45 ports for standard Ethernet communication and two 100Base‑FX multimode fiber uplink ports with LC‑type connectors, enabling flexible network topology and extended reach.

This switch conforms to key industry standards, including IEEE 802.3, 802.3u, and 802.3x, and incorporates features such as auto‑negotiation, HP‑MDIX auto‑sensing, full/half‑duplex operation, and comprehensive LED indicators for link status, activity, speed, duplex, and power. With redundant 24 VDC power inputs (Diode‑OR’d), it enhances network reliability and supports continuous operation in mission‑critical applications.

Constructed for industrial durability, the IS420ESWBH2A can be mounted on DIN rails or within control racks, offering high tolerance to temperature extremes (typically −40 °C to +70 °C) and an IP20 protection rating. Its rugged design and proven performance make it a trusted component for real‑time Ethernet networks in automated control systems.
