The GE IS420ESWBH3A Ethernet IONet Switch Module is mainly used in GE gas turbine control systems to achieve efficient data transmission and exchange. The following is an introduction to its functions, parameters, and application scenarios:

Functional Introduction
Network Protocol Compatibility: It supports 802.3, 802.3U, and 802.3x Ethernet standards, ensuring compatibility with a variety of standard-compliant network devices.
Auto-Negotiation Function: It has 10/100Base-TX auto-negotiation capability, which can automatically detect and adapt to the speed and duplex mode of connected devices. It also supports full/half-duplex auto-negotiation, eliminating the need for frequent manual configuration.
Port Auto-Sensing: It is equipped with HP-MDIX auto-sensing function, which can automatically identify and adjust the network cable connection mode, facilitating network cabling.
Data Buffering: It is provided with a minimum 256KB buffer and 4K Media Access Control (MAC) addresses, which can effectively buffer and process data, improving the stability and efficiency of network data transmission.
Status Indication: Each port is equipped with LED indicators, which can display the link presence, activity, duplex, and speed status. There is also a power indicator for real-time monitoring of the module’s working status.

Main Parameters
Number of Ports: Usually, there are 16 10/100Base-TX copper RJ-45 ports, and some data shows 8 ports. It is also equipped with a 100Mbps FX uplink port.
Power Requirements: It is generally powered by 24V or 28V DC power supply, with a redundant power input design to improve power supply reliability.
Operating Temperature: The operating temperature range is -40℃ to 70℃, adapting to a wide range of industrial environment temperatures.
Installation Method: It supports DIN rail mounting, which can be installed in parallel or vertically, and can also be panel-mounted through screw holes.
Physical Dimensions: Approximately 18.8 cm in height x 8.6 cm in width x 5.6 cm in depth.
Humidity Requirement: The relative humidity is 5% to 95% in a non-condensing environment.

Application Scenarios
Gas Turbine Control Systems: As part of the GE Speedtronic Mark VIe gas turbine control system, it is used to manage the control data transmission of a single turbine or the entire plant, ensuring stable and efficient data transmission during the operation of various components of the gas turbine and guaranteeing the normal operation of the gas turbine.
Industrial Automation Field: It is suitable for other industrial automation scenarios with high requirements for network reliability and real-time performance. It can provide support for data communication between industrial equipment in industries such as electric power and energy, realizing collaborative work and monitoring between devices.
