GE IS420ESWBH3A is an Ethernet IONet switch manufactured by General Electric(GE).It is an important part of the GE Speedtronic Mark VIe gas turbine control system.The following is a detailed introduction to the GE IS420ESWBH3A:

I.Product Overview

The GE IS420ESWBH3A Ethernet switch is designed to meet the needs of real-time industrial control solutions and is required for all IONet switches used in Mark VIe and VIeS safety control systems.It provides high-speed,reliable data transmission,ensuring the stability and efficiency of the gas turbine control system.

II.Technical Specifications

Number of ports:The GE IS420ESWBH3A has 16 copper ports(some say 8 ports),which support 10/100BASE-TX connections and have auto-negotiation capabilities to automatically identify and configure connected devices.

Connection method:Use RJ-45 connectors to support multiple insertions and removals,with an expected service life of 200 insertion/removal cycles.

Power supply:The switch operates at 24/28VDC and has a redundant power input function.When one power supply fails,the other power supply can continue to provide power to the switch to ensure its normal operation.

Indicator:The LED indicator is used to indicate the status of the link presence,activity,duplex and speed ports,as well as the power status.When the link indicator is solid yellow,it means that a 10MB link is in use;when it is solid green,it means that a 100MB link is in use;if no indicator is on,it means that there is no link.The color of the activity LED is also green and yellow,but they will flash.When the LED flashes green,it means that the activity is in full-duplex state,and when it flashes yellow,it means that the activity is in half-duplex state.

Buffer:A minimum 256KB buffer helps optimize data transmission efficiency.

MAC address:It has a 4K media access control(MAC)address.

Installation method:It adopts a DIN rail mounting module design and can be installed on the control system panel.At the same time,it meets vibration and shock requirements and can withstand harsh working environments.

3.Product Features

High-speed transmission:GE IS420ESWBH3A provides high-speed data transmission capability,ensuring the real-time and accuracy of the gas turbine control system.

High stability:The redundant power input function and high-quality hardware design make the switch highly stable and able to operate stably in harsh industrial environments.

Easy installation:The DIN rail mounting module design makes the installation process simple and quick.

Compatibility:The switch is compatible with Ethernet standards such as 802.3,802.3u and 802.3x,and can be seamlessly integrated with other Ethernet devices.

4.Application areas

GE IS420ESWBH3A Ethernet switch is widely used in various industrial automation and control system scenarios,such as power,petroleum,chemical,steel and papermaking industries.In these industries,as an important part of the gas turbine control system,it provides strong support for the stability and efficiency of the system.
