Product Information
Full details
The Phoenix Contact 2900299 (PLC-RPT-24DC/21) is an interface relay module designed for reliable signal conversion and load switching in industrial environments. It's ideal for engineers and technicians working with power electronics and automation systems, offering a slim design and efficient integration. A key benefit is its safe isolation between coil and contact, ensuring operational safety. However, its DC input voltage requirement means it's not directly compatible with AC control signals without additional conversion.

Extended Product Information
FAQs
What is the input voltage requirement for the Phoenix Contact 2900299?
The module requires a 24 V DC input voltage for its coil.
What type of connection does the terminal block use?
It uses Push-in connection technology for fast and tool-free wiring.
Can this relay switch AC loads?
Yes, it is suitable for AC loads within its specified switching capacity. Always refer to the product datasheet for exact ratings.
What is the benefit of the 'RT III sealed relay' feature?
The RT III sealing provides protection against dust and moisture, ensuring reliable operation in harsh environments.
How does the safe isolation feature work?
It provides electrical separation according to DIN EN 50178 between the coil circuit and the contact circuit, enhancing safety by preventing hazardous voltages from bridging between them.
What is the operating temperature range?
The module can operate within a temperature range of -40 °C to 60 °C.
How can I efficiently wire multiple modules together?
Phoenix Contact offers functional plug-in bridges and V8 adapters that facilitate efficient wiring for multiple modules connected to system cabling.
Troubleshooting
Relay does not switch on.
Verify that the 24 V DC input voltage is correctly applied to the coil terminals and that the polarity is correct. Check for continuity of the control signal.
Load is not being switched.
Confirm that the relay is energizing. Check the connections to the load and ensure the load itself is functional. Verify the relay's contact ratings are not exceeded by the load.
Intermittent operation or failure.
Ensure the operating temperature is within the specified range (-40 to 60 °C). Check for vibration that might affect the relay contacts. Inspect for any signs of contamination on the relay or terminals.
Poor connection at terminals.
Ensure solid core wires are used for Push-in connections. If using stranded wire, ensure it is properly terminated with ferrules. Re-seat the wire firmly into the terminal.
Pros and Cons
Pros
- Space-saving slim design suitable for compact control panels.
- Tool-free wiring thanks to Push-in connection technology.
- Enhanced safety through electrical isolation between coil and contact.
- Robust and reliable due to RT III sealed relay protection.
- Efficient integration into existing system cabling with optional V8 adapters.
- Built-in input and interference suppression circuits simplify implementation.
Cons
- Requires a 24 V DC power supply, not directly compatible with AC control.
- Single changeover contact (1 PDT) limits complex switching configurations.
- Dimensions can be critical in extremely space-constrained applications, despite its slim design.
- Specific adapter might be needed for efficient system cabling integration.
- Not suitable for direct high-power AC load switching without an intermediate relay or contactor.
Setup, Compatibility & Care
Setup:
- Mount the PLC-RPT-24DC/21 module onto a standard NS 35/7.5 DIN rail.
- Connect the control input signals to the designated terminals on the basic terminal block using Push-in technology. Ensure correct polarity for the 24 V DC input.
- Connect the load to be switched to the output terminals of the relay.
- If using system cabling, refer to the documentation for compatibility with V8 adapters or other bridge systems.
Compatibility:
- Input Voltage: Requires a stable 24 V DC power supply.
- Mounting: Compatible with NS 35/7.5 DIN rails.
- Cabling: Can be integrated into systems using Phoenix Contact's V8 adapter or similar bus systems for efficient wiring.
- Load Type: Suitable for AC loads within its switching capacity limits (refer to datasheet for specifics).
Care:
- Keep the module clean and free from dust and moisture, especially around the relay encapsulation.
- Ensure proper ventilation in the control cabinet to prevent overheating.
- Periodically check connections for tightness and signs of wear, although Push-in connections are generally maintenance-free.
