FINDER 20.22.8.024.4000 impulzné relé 24 V AC 2 NO 16 A DIN lišta

With a rated contact current of 16 A and a coil voltage of 24 V AC, the FINDER 20.22.8.024.4000 step relay delivers robust switching for lighting and automation circuits. This DIN rail mounted module provides two normally open contacts and is engineered for high electrical endurance.

Overview

The FINDER 20.22.8.024.4000 is a step relay (impulse switch) designed for staircase lighting, corridor lighting, and other applications where a single pushbutton controls a load from multiple locations. Each pulse of the coil toggles the relay state, eliminating the need for latching switches. It features screw terminals for secure wiring and a compact 1-module width (17.5 mm) for efficient use of distribution board space.
