Phoenix Contact 2903354

The relay module, designated as RIF-1-RSC-LDP-24DC/1X21AU, is a pre-assembled unit designed with a screw connection. It comprises several components including a relay base, a multi-layer contact relay, a plug-in display/interference suppression module, and a retaining bracket. This module operates with an input voltage of 24 V DC.

In terms of dimensions, the module measures 16 mm in width, 89 mm in height, and 75 mm in depth. The device supports multiple conductor cross-sections, accommodating both solid and flexible wires ranging from 0.5 mm² to 4 mm², with stripping lengths of 8 mm. The contact side features a single changeover contact made from AgNi material, with a maximum switching voltage of 36 V DC and a minimum switching current of 1 mA.

The relay module is engineered to function within an ambient temperature range of -40 °C to 70 °C, and is designed for DIN rail mounting with an IP20 degree of protection for the relay base. It complies with several standards, including DIN EN 50178, ensuring safe isolation and a rated surge voltage of 6 kV.

Additional features include a typical input current of 18 mA with a response time of 8 ms, coupled with a power dissipation of 0.43 W in nominal conditions. The module supports a mechanical service life of approximately 30 million cycles, illustrating its suitability for universal applications in automation systems.
