ETI RELAY PHOTO ETS-16B 230V/16A 02471102 Photoelectric Relay with Adjustable Light Sensor

Managing outdoor lighting based on ambient light levels can be a hassle without the right control. The ETI RELAY PHOTO ETS-16B solves this by automatically switching a 16A circuit according to a preset light threshold, using an external photoelectric probe. Ideal for controlling street lamps, garden lights, or signage, it eliminates the need for manual switching and reduces energy waste.

Who is it for

This photoelectric relay is perfect for electricians, facility managers, and homeowners who need reliable automatic lighting control for outdoor or industrial applications. Whether you're automating a single floodlight or a lighting circuit, this DIN-rail mounted module provides a compact and robust solution.

Tips

For best results, mount the photoelectric probe in a location that represents the ambient light level you want to control, away from direct artificial light sources to avoid feedback loops. Adjust the threshold and time delay during commissioning to match the specific lighting conditions and avoid nuisance switching.
