GE IS420ESWBH3A Mark VIe Ethernet Switch Module

GE IS420ESWBH3A is a high-reliability Ethernet switch module belonging to GE’s Mark VIe series of industrial control system components (General Electric Company). 

It features 8 x 10/100 Base-TX RJ45 Ethernet ports, supporting multiple industrial communication protocols such as Ethernet/IP, Modbus TCP/IP, UDP, TCP, ICMP, and DHCP, 

enabling seamless data transmission between industrial control systems, distributed I/O modules, and field devices. The module adopts a high anti-interference design, 

fully adapting to harsh industrial environments, with 24V DC input (±10% tolerance), maximum input current of 1.5A, and typical power consumption of 25W (max 30W), 

ensuring stable operation under various working conditions.

It is equipped with multiple protection mechanisms including overvoltage protection, overcurrent protection, and ESD protection (±15kV), effectively preventing damage caused 

by power fluctuations and electrostatic interference. The module supports natural convection cooling (optional forced air cooling) for efficient heat dissipation, with an operating 

temperature range of -40°C to +70°C and relative humidity of 5% to 95% (non-condensing), fully compliant with industrial-grade environmental requirements. It is seamlessly 

compatible with GE Mark VIe distributed control system (DCS) and Proficy software suite, realizing unified monitoring and management of the communication network, 

and improving system operability and maintainability.

Widely deployed in power generation, petrochemical, metallurgy, and other industrial fields, this module serves as a core network communication component for critical industrial 

control systems. We supply new, original, and refurbished GE IS420ESWBH3A modules, all fully tested with warranty and fast global delivery, ensuring stable and reliable operation 

of your industrial control communication system.
