Phoenix Contact 2903357

The relay module, designated as RIF-1-RSC-LV-24AC/1X21, is engineered for 24 V AC applications. It features a monostable design with a single changeover contact. This assembly includes a relay base, a power contact relay, and a plug-in display/interference suppression module, all secured by a retaining bracket.

With an input voltage range of 19.2 V AC to 27.6 V AC at 20 °C, the module operates effectively within a mains frequency of 50/60 Hz. Notably, it possesses a mechanical service life of approximately 10⁷ cycles, ensuring reliability in various applications. The insulation provides safe isolation between input and output, with a rated insulation voltage of 250 V AC and a rated surge voltage of 6 kV.

Further enhancing its functionality, the module supports a typical input current of 33 mA and responds within 3 ms to 12 ms. The design allows for a maximum switching voltage of 250 V AC/DC and a limiting continuous current of 10 A. Additionally, it features a protective circuit with a varistor and an operating voltage display indicated by a yellow LED.

Constructed for DIN rail mounting, this module can be positioned in any orientation and operates effectively in ambient temperatures ranging from -40 °C to 50 °C. Its robust design also complies with IEC 60947-5-1 standards, making it suitable for diverse industrial environments.
