## Long description

The Phoenix Contact PLC-RPT 24DC/21 is a professional-grade interface relay module designed for demanding industrial automation and control environments. This compact unit combines a high-performance PLC-BPT basic terminal block with a reliable plug-in miniature relay, providing a robust solution for signal switching and isolation. Engineered for efficiency, it features advanced push-in connection technology that facilitates rapid, tool-free wiring, ensuring secure electrical contact even in high-vibration applications.
Advantages
This interface relay offers significant benefits for modern control cabinet design, primarily through its space-saving footprint and modular architecture. The integration of push-in technology drastically reduces installation time and maintenance efforts compared to traditional screw-clamp terminals. Its high-quality power contact ensures consistent performance and long service life, while the pluggable design allows for quick replacement of the relay element without disturbing existing wiring, thereby minimizing system downtime.
Suitable for
Industrial automation control systems
Signal isolation between PLC outputs and field devices
Amplification of low-power control signals
Compact control cabinet installations
Applications requiring frequent maintenance or rapid component replacement
When it may not be suitable
This relay is designed specifically for 24V DC control circuits and is not suitable for direct switching of high-voltage AC mains or high-current loads exceeding its 6A rating. It should not be used in environments where the ambient temperature or humidity levels exceed the manufacturer's specified operating range.
Key specifications
Input voltage: 24V DC
Contact configuration: 1 PDT (Single Pole Double Throw)
Switching capacity: 6A
Connection method: Push-in technology
Mounting type: NS 35/7,5 DIN rail
How to use
To install the relay, snap the base terminal block onto a standard NS 35/7,5 DIN rail. Connect your control and load wires by inserting the stripped conductors directly into the push-in terminals until they are firmly seated. Ensure that the plug-in miniature relay is correctly inserted into the base block. Verify that the input voltage matches the 24V DC specification before energizing the circuit.
What to consider before purchase
Verify that your control system output provides a 24V DC signal.
Ensure the load current does not exceed the 6A limit.
Confirm that your DIN rail system is compatible with the NS 35/7,5 standard.
Check the available space in your control cabinet for the module dimensions.
Usage recommendations: Always ensure that the power supply is disconnected before performing any wiring or maintenance tasks. Regularly inspect the push-in connections to ensure they remain secure and free from debris or oxidation.
