2. Building Automation HVAC/Lighting Control

The WAGO 286-304 can control HVAC dampers, small fan motors, or lighting circuits (up to 7A) in commercial or industrial building automation systems. The common 24VDC control voltage integrates seamlessly with building management systems, and its ability to switch 250VAC makes it versatile for various electrical loads. The -25 to 70 °C operating temperature range is well-suited for indoor climate-controlled environments.

Problem Solved

Enables robust and compact switching of higher voltage AC loads (e.g., lights, small motors) in building automation systems powered by 24VDC control signals, maintaining stability across a typical indoor temperature range.
