Phoenix Contact 2903671

The REL-IR4/LDP- 48DC/4X21AU is a plug-in industrial relay designed for robust applications. It includes four changeover contacts and incorporates additional hard gold plating for enhanced durability. The device is equipped with a test button and a status LED for operational feedback. Its mechanical switching position indicator aids in visual confirmation of the relay's state.

With a coil voltage of 48 V DC, the relay operates within a voltage range of 38.4 V DC to 86.4 V DC at 20 °C, drawing a typical input current of 22 mA. The response and release times are approximately 13 ms and 14 ms, respectively. The relay supports a maximum inrush current of 16 A for 20 ms, with a limiting continuous current of 6 A.

Designed for versatility, it can be mounted in any position and is rated for operation in ambient temperatures ranging from -40 °C to 70 °C. The relay meets the standards of IEC 60664 and is built to handle an overvoltage category of II and pollution degree of 2. The device's dimensions are 21.2 mm in width, 27.5 mm in height, and 35.6 mm in depth.
