Phoenix Contact 2903318

The RIF-2-RSC-LV-24AC/4X21 is a pre-assembled relay module designed for versatile applications. It incorporates a relay base and a power contact relay, ensuring reliable performance. The module includes a plug-in display/interference suppression component and a retaining bracket for secure installation.

Operating at an input voltage of 24 V AC, this unit supports an input voltage range of 19.2 V AC to 28.8 V AC at 20 °C and is suitable for both 50 and 60 Hz mains frequencies. The contact configuration consists of 4 changeover contacts, which allow for flexible switching options.

With a typical input current of 66 mA at nominal voltage and a maximum switching voltage of 250 V AC/DC, this relay module is engineered for demanding environments. The mechanical service life is approximately 20 million cycles, and the insulation rating is basic, categorized under overvoltage category II and pollution degree 2.

Installation is simplified with a DIN rail mounting type, and the relay base is rated at IP20 for protection. The ambient operating temperature ranges from -40 °C to 50 °C, while storage conditions can reach up to 85 °C.
