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

The Phoenix Contact RIF-1-RPT-LDP-24DC/1X21 is a pre-assembled relay module engineered for industrial automation and control systems. This compact unit combines a robust relay base with a high-performance power contact relay, featuring integrated status indication and protective circuitry. Utilizing advanced Push-in connection technology, the module allows for rapid, tool-free wiring, significantly reducing installation time while ensuring secure electrical contact in demanding environments.

Advantages

The primary advantage of this module is its pre-assembled design, which simplifies procurement and installation by providing a complete, ready-to-use solution. The Push-in connection system facilitates efficient wiring even in confined spaces, supporting a wide range of conductor cross-sections. Integrated features such as the yellow LED status indicator and protective diodes for freewheeling and reverse polarity protection enhance operational safety and simplify troubleshooting. The module is built to withstand harsh industrial conditions, offering reliable performance across a broad temperature range.

Suitable for

• Industrial automation and control systems
• Signal isolation and amplification
• Switching of electrical loads in control cabinets
• 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 ratings. It is not intended for use in environments with extreme vibration or corrosive atmospheres that exceed the specified protection class.

Key specifications

• Nominal voltage: 24 V DC
• Contact type: 1 PDT (single-pole double-throw)
• Connection technology: Push-in
• Conductor cross-section: 0.14 to 1.5 mm²
• Switching capacity: 2 A at 24 V DC / 6 A at 230 V AC
• Operating temperature: -40 °C to +70 °C
• Integrated features: Yellow LED status indicator, freewheeling diode, reverse polarity protection

How to use

The relay module is designed for mounting on standard DIN rails. To install, simply snap the module onto the rail until it locks into place. Connect your control and load wires directly into the Push-in terminals by inserting the stripped conductors. The integrated status LED provides immediate visual feedback on the relay state. Ensure that the supply voltage matches the 24V DC specification to prevent damage to the internal components.

What to consider before purchase

• Verify that the 24V DC control voltage is compatible with your existing system architecture.
• Ensure the switching current and voltage requirements of your load do not exceed the module's rated capacity.
• Check available space in your control cabinet to accommodate the module dimensions.
• Confirm that the wire gauge used is within the supported range of 0.14 to 1.5 mm².

Usage recommendations

For optimal longevity and performance, ensure the module is installed in a well-ventilated area within the specified temperature range. Periodically inspect the Push-in connections to ensure they remain secure, especially in environments subject to thermal cycling.
