Phoenix Contact 2903684

The REL-IR4/L-120AC/4X21AU is a plug-in industrial relay that incorporates power contacts along with hard gold plating for enhanced durability. This model is equipped with four changeover contacts, a mechanical switching position indicator, and a test button for operational verification. The coil operates at a voltage of 120 V AC.

With a typical input current of 13 mA and a response time that varies between 5 ms and 15 ms depending on phase relation, this relay ensures reliable switching performance. It features a mechanical service life of approximately 20 million cycles and operates effectively within an ambient temperature range of -40 °C to 55 °C. The relay's contact material is AgNi, providing robust performance under maximum switching conditions of 250 V AC/DC and a limiting continuous current of 6 A.

For added safety, the relay meets insulation specifications with a rated insulation voltage of 250 V AC and a test voltage of 2.5 kVrms between winding and contacts. The degree of protection is classified as RT I, ensuring suitability for various industrial applications. Compliance with IEC 60664 standards further affirms its reliability in operational settings.
