## Long description

The Phoenix Contact RIF-2-RPT-LDP-24DC/4X21 is a pre-assembled relay module designed for reliable signal switching in industrial automation and control cabinet environments. This unit features four changeover contacts (4 PDT) and operates with a 24V DC coil voltage. It is engineered for efficiency, utilizing Push-in connection technology that allows for quick, tool-free wiring of conductors ranging from 0.14 to 1.5 mm². The module comes as a complete set, including the relay base, the power contact relay, and a retaining bracket for secure installation.
Advantages
This relay module offers significant benefits for modern control systems, primarily through its integrated status LED and protective circuitry. The yellow LED provides clear visual feedback on the operating state, while the built-in freewheeling diode and reverse polarity protection ensure the longevity of the components and the safety of the connected control electronics. The use of AgNi contact material provides excellent switching reliability, and the Push-in connection system drastically reduces installation time compared to traditional screw terminals, making it an ideal choice for high-density wiring applications.
Suitable for
Industrial automation control panels
Signal isolation and amplification
Interface relay applications
Automation systems requiring 4 PDT switching
When it may not be suitable
This module is designed for specific voltage and current ratings and may not be suitable for high-power motor switching or applications exceeding the 6A maximum current limit. It is intended for indoor use within control cabinets and is not suitable for direct outdoor exposure without additional protective housing.
Key specifications
Contact type: 4 changeover (4 PDT)
Coil voltage: 24V DC
Connection technology: Push-in
Conductor cross-section: 0.14 - 1.5 mm²
Switching current: 6A
Switching voltage: 250V AC/DC
Operating temperature: -40°C to +60°C
Integrated features: Yellow LED status 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 and insert the relay into the socket, securing it with the provided retaining bracket. Connect your control and load wires directly into the Push-in terminals by inserting the stripped conductor until it clicks into place. Ensure the polarity of the 24V DC supply matches the markings on the module to utilize the integrated protection features correctly.
What to consider before purchase
Verify that your control system output matches the 24V DC coil requirement.
Ensure the load requirements do not exceed the 6A switching capacity.
Check available space in your control cabinet for DIN rail mounting.
Confirm that the wire gauge used is within the 0.14 to 1.5 mm² range.
Usage recommendations: Always ensure the power is disconnected before performing any wiring tasks. Regularly inspect the relay module for signs of wear or environmental debris, especially in high-vibration or dusty industrial environments, to maintain optimal performance.
