The IS420ESWAH3A GE Ethernet switch supports real-time data transmission, redundant architecture, and high reliability, meeting the requirements of industrial automation for harsh environments (such as wide temperature ranges, vibration resistance, and electromagnetic compatibility). It features eight 10/100Base-TX copper ports with auto-negotiation (full/half duplex) and LED status indicators (link/activity/speed). It can be used with fiber optic modules for long-distance communication and supports industrial protocols such as PROFIBUS and Modbus. When combined with other GE modules (such as the ESWBH series switches), it can build dual-redundant networks to ensure high availability of communication links.
