Phoenix Contact RIF-0-RPT-24DC/21 Power Relay Module, 24V DC, 1 PDT, 6A

The Phoenix Contact RIF-0-RPT-24DC/21 is a compact, pre-assembled industrial relay module engineered for efficient signal switching and electrical isolation in automation environments. This module features a 24V DC coil voltage and a 1 PDT contact configuration, capable of handling a nominal current of 6A. Designed for high reliability, it integrates seamlessly into industrial control panels where space is at a premium, providing a robust interface between control logic and field devices.

Advantages

The primary advantage of this relay module is its advanced Push-in connection technology, which facilitates rapid, tool-free wiring, significantly reducing installation time and labor costs. The compact design allows for high-density mounting in electrical cabinets, maximizing available space. Furthermore, the module includes a yellow LED status indicator for clear visual monitoring of the operating state and a built-in freewheeling diode for effective protection against voltage spikes, ensuring the longevity of both the relay and connected control components.

Suitable for

• Industrial automation and control systems
• Signal isolation between PLC outputs and field devices
• Space-constrained electrical control cabinets
• General switching applications requiring a 1 PDT configuration

This module may not be suitable for applications requiring high-power switching beyond its 6A rating or for environments where the ambient temperature consistently exceeds the specified range of -40 to +60 °C. It is also not intended for use in high-vibration environments without appropriate mounting considerations.

Key specifications

• Coil voltage: 24V DC
• Contact configuration: 1 PDT (Single Pole Double Throw)
• Maximum switching current: 6A
• Maximum switching voltage: 250V AC/DC
• Connection type: Push-in (0.14 - 1.5 mm²)
• Operating temperature: -40 to +60 °C
• Integrated features: Yellow LED status indicator and freewheeling diode

Installation is straightforward due to the pre-assembled nature of the unit, which includes the relay base, ejector, and power contact relay. Simply mount the module onto a standard DIN rail and insert your conductors directly into the Push-in terminals without the need for specialized tools. Ensure that the wire cross-section is within the specified range of 0.14 to 1.5 mm² for a secure connection.

What to consider before purchase

• Verify that the 24V DC control voltage matches your system requirements.
• Ensure the 6A switching capacity is sufficient for your specific load.
• Check that the available space in your cabinet accommodates the module dimensions.
• Confirm that the environmental conditions remain within the -40 to +60 °C operating range.

For optimal performance and safety, ensure that all electrical connections are firmly seated and that the module is protected from excessive moisture and dust. Regularly inspect the LED indicator to confirm proper relay operation during routine maintenance cycles.
