GE IS420ESWBH3A is an unmanaged Ethernet switch designed for industrial environments.It is mainly used in GE’s Mark VIe security control system and real-time industrial control scenarios.The following is a comprehensive overview of its core functions and technical parameters:
I.Core functions and design
Industrial performance
-Port configuration:Provides 16 10/100Base-TX copper ports(RJ45 interface),supports full/half-duplex auto-negotiation,and no fiber port version.
-Protocol compatibility:Complies with 802.3,802.3u and 802.3x standards,supports auto-negotiation function,and ensures seamless connection with different devices.
Reliability and redundancy design
-Redundant power input:Adopts dual power input(24/28 VDC),supports hot backup,and can switch seamlessly when a single power supply fails,improving system stability.
-Wide temperature operation:Adapts to industrial environments from-40°C to 70°C,resists vibration and shock,and meets long-term operation requirements under harsh conditions.
Buffering and data processing
-Minimum 256KB buffer:Each port can buffer at least one data packet,optimizing the transmission efficiency of broadcast/multicast data streams.
-4K MAC address table:supports large-scale device connection and data forwarding.
2.Installation and deployment
Flexible installation method
-DIN rail or panel installation:supports parallel/vertical DIN rail installation(special clamps are required),or fixed to the panel by screws,compatible with third-party mounting brackets.
-Anti-seismic design:DIN rail installation meets vibration and shock standards to ensure device stability.
Interfaces and indicators
-LED indication:Each port is equipped with a two-color LED to display the link status(green/yellow),activity status and duplex mode;the power indicator independently displays the power supply status of the device.
3.Application scenarios
Industrial control field
-Gas turbine control:As a core component of the Mark VIe system,it supports real-time data transmission and safe redundant architecture(such as TMR triple modular redundancy).
