• 230 V AC operating voltage, 50/60 Hz, with 1 NO contact for switching lighting circuits
• Supports incandescent/halogen loads up to 2000 W, fluorescent up to 1000 VA, and LED up to 200 W

• IP20 protection, suitable for indoor electrical enclosures

In daily use

Install the Rex900 on a DIN rail in your electrical panel, connect the lighting circuit to the screw terminals, and set the desired time delay from 0.5 to 10 minutes. When a push button is pressed, the timer energizes the lighting for the set duration, then switches off automatically. The manual override allows you to keep lights on continuously for maintenance or off during daylight hours. Its compact 1-module design saves space, and the clear front switch makes operation straightforward.
