Phoenix Contact 2903683

The Single Relay REL-IR4/L- 24AC/4X21AU is designed for industrial applications requiring reliable switching. This relay features four changeover contacts and is constructed with hard gold plating to enhance durability. The coil operates at a nominal voltage of 24 V AC, with an input voltage range of 18.7 V AC to 33.1 V AC at 20 °C.

In addition to its robust design, the relay includes a test button and a status LED for easy monitoring. The mechanical service life is approximately 20 million cycles, ensuring long-term reliability. It has a typical response time of 5 to 15 milliseconds, depending on the phase relation, and a typical release time ranging from 5 to 20 milliseconds.

Electrical ratings include a maximum switching voltage of 250 V AC/DC and a minimum switching voltage of 5 V at 24 mA. The relay can handle a maximum inrush current of 16 A for 20 ms and has a limiting continuous current of 6 A. It is designed to operate in ambient temperatures from -40 °C to 55 °C and has a degree of protection classified as RT I. Compliance with IEC 60664 standards ensures its suitability for harsh environments, categorized as ISA-S71.04 G3.
