Ethernet-APL Field Switches for Hazardous Areas
Ethernet-APL is transforming process automation by allowing high-speed Ethernet communication directly to field devices in hazardous areas. Designed for long cable runs, power delivery and intrinsic safety concepts, Ethernet-APL is becoming a preferred technology for modern plants.
R. STAHL Series 9740 field switches provide a practical route to implementing Ethernet-APL in Zone 1 and Zone 2 environments. With support for up to 16 field devices, integrated diagnostics and robust industrial design, they help simplify digital networking in demanding process applications.
Whether upgrading legacy PROFIBUS PA systems or planning future-ready plant infrastructure, Exloc can help specify the right hazardous area networking solution.
Zone 1 vs Zone 2 Ethernet-APL Switches
Zone 1 versions are designed for installation where explosive atmospheres may occur occasionally during normal operation, while Zone 2 models are intended for areas where explosive atmospheres are less likely and only present for short periods. Choosing the correct switch depends on site classification and project requirements.
