ABB TEU471-EX.A P.11471-0-3011011 F.6.880581.2 Industrial Control Board
The ABB TEU471-EX.A is an explosion-proof terminal unit designed for hazardous environments. Key specs include ATEX/IECEx certification, -40°C to +70°C operating temp, and 24VDC power supply. It's commonly used in oil & gas, chemical, and pharmaceutical industries for connecting field devices in Zone 1/21 areas. Compared to the ABB DO572, the TEU471-EX.A offers enhanced safety features but has fewer I/O channels. The ABB CI534V04, while also explosion-proof, is focused on vibration monitoring, making the TEU471-EX.A more versatile for general I/O applications in hazardous zones.
