Phoenix Contact RIF-1-RPT-LDP-24DC/2X21 Relay Module, 24V DC, 2 PDT

The Phoenix Contact RIF-1-RPT-LDP-24DC/2X21 is a pre-assembled relay module engineered for demanding industrial control environments. This robust unit combines a relay base, a power contact relay, a pluggable display and interference suppression module, and a retaining bracket into a single, ready-to-use solution. Featuring advanced Push-in connection technology, it allows for tool-free, vibration-resistant wiring, significantly reducing installation time while maintaining high electrical reliability.

Advantages

This relay module offers exceptional operational efficiency through its integrated design, which eliminates the need for complex assembly of individual components. The inclusion of a yellow LED status indicator and built-in protection circuitry, such as a freewheeling diode and reverse polarity protection, ensures safe and clear monitoring of the switching state. The AgNi contact material provides excellent conductivity and durability, making it suitable for frequent switching operations in automation systems. Its compact design and wide operating temperature range allow for flexible installation in various control cabinets and industrial settings.

Suitable for

• Signal isolation in automation systems
• Amplification of control signals
• Switching of electrical loads in industrial machinery
• Interface applications between controllers and field devices

When it may not be suitable

This module is designed for standard industrial control voltages and may not be suitable for high-power switching applications exceeding the specified current or voltage limits. It is also not intended for use in environments with extreme corrosive gases or high levels of moisture that exceed standard industrial protection ratings.

Key specifications

• Coil voltage: 24 V DC
• Contact configuration: 2 PDT (double-pole double-throw)
• Connection type: Push-in connection (0.14 - 1.5 mm²)
• Switching current: 8 A
• Switching voltage: 250 V AC/DC
• Operating temperature range: -40 °C to +70 °C
• Integrated features: Yellow LED indicator, freewheeling diode, reverse polarity protection

How to use

The module is designed for mounting on standard DIN rails. To install, simply snap the base onto the rail. Connect your control and load wires directly into the Push-in terminals by inserting the stripped conductors until they are securely locked. The module comes pre-assembled, so no additional configuration of the relay or suppression module is required. Ensure that the supply voltage matches the 24V DC rating before activation.

What to consider before purchase

• Verify that the 24V DC control voltage matches your system requirements.
• Ensure the load current does not exceed the 8A maximum rating.
• Check available space in the control cabinet for DIN rail mounting.
• Confirm that the wire cross-section (0.14 - 1.5 mm²) is compatible with your cabling.

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring tasks. Regularly inspect the connections and the status LED to ensure optimal performance and to detect potential faults early in the system lifecycle.
