ENTERASYS A4H124-24TX Industrial Ethernet Switch Module

This 24-port industrial Ethernet switch delivers rock-solid connectivity for automation systems where network downtime isn’t an option. Designed to handle the rigors of factory floors and energy plants, it keeps critical control systems talking even under harsh conditions.

We’ve seen this switch become the backbone of networks in automotive assembly lines and oil refinery control rooms. Its ability to maintain connections when vibration or temperature swings would kill regular hardware makes it a favorite among our clients. One engineer in a steel plant told me how it kept their conveyor belt system running even with 50°C ambient temperatures and constant mechanical shock.

Technical Advantages

What sets this module apart isn’t just its metal housing or -40°C to +75°C operating range. The real magic’s in how it handles network traffic – VLAN tagging keeps different system segments talking without cross-talk, while QoS prioritizes urgent control signals over less critical data. I’ve had clients in chemical plants use the port mirroring feature to troubleshoot safety system communications without disrupting ongoing processes.
