Phoenix Contact 24V DC Relay Module with 6A Switching Current, 1 NO

Phoenix Contact 24V DC Relay Module

The Phoenix Contact PLC‑RPT‑24DC/1/MS/ACT is a compact, high‑performance relay module designed for industrial automation and control applications. It operates on a nominal voltage of 24 V DC and can switch currents up to 6 A, making it suitable for driving relays, contactors, or other low‑current devices in PLC (Programmable Logic Controller) systems.

Key Technical Specifications

• Nominal Voltage: 24 V DC
• Maximum Switching Current: 6 A
• Contact Configuration: 1 Normally Open (NO)
• Mounting Type: Surface Mount / Plug‑In – compatible with standard PLC chassis and DIN rail systems.
• Operating Temperature Range: Typically from -40 °C to +70 °C, ensuring reliable performance in harsh industrial environments.
• Mechanical Dimensions: Compact footprint (approx. 30 mm × 20 mm) for tight integration into control panels.
• Electrical Isolation: High isolation voltage between input and output to protect sensitive circuitry.

Functional Overview

The module receives a control signal from the PLC’s digital output. When the input is activated, the internal relay contacts close, allowing current to flow through the NO contact. This action can energize motors, lamps, solenoids, or other peripheral devices that require a 24 V DC supply.

Because it features a single Normally Open (NO) contact, the module is ideal for applications where a simple on/off control is required without the need for multiple contact configurations. The NO contact ensures that the load remains disconnected until the PLC explicitly commands it to close, providing precise control over connected equipment.

Installation and Integration

• Plug‑In Interface: The module uses a standard push‑in connector (PLC‑BPT/ACT) for quick and secure wiring. This design eliminates the need for soldering or terminal blocks, reducing installation time.
• DIN Rail Compatibility: While primarily designed as a plug‑in unit, the module can be mounted on standard DIN rails using optional brackets, allowing flexible placement within control cabinets.
• Wiring Diagram: Connect the PLC output to the input terminals of the module. Wire the load between the NO contact and the 24 V DC supply line. Ensure that all connections are secure and insulated to prevent short circuits.

Typical Applications

• Control of small motors or actuators in conveyor systems.
• Activation of indicator lamps, status lights, or warning signals.
• Switching of solenoids for pneumatic or hydraulic valves.
• Power management for auxiliary devices such as fans or pumps.

Reliability and Durability

Phoenix Contact is renowned for its robust industrial components. The relay module incorporates high‑quality materials that resist wear, corrosion, and temperature fluctuations. Its 6 A switching capability ensures that it can handle moderate load currents without overheating or degrading over time.

Compliance and Standards

The module meets stringent industrial standards for safety and performance, including:

• IEC 60947‑2 – Low voltage switchgear and control gear.
• EN 60204‑1 – Safety of machinery – Electrical equipment of machines.
• ISO 9001 – Quality management systems certification for manufacturing processes.

Conclusion

The Phoenix Contact PLC‑RPT‑24DC/1/MS/ACT Relay Module offers a reliable, compact solution for controlling 24 V DC loads up to 6 A. Its simple NO contact configuration, plug‑in interface, and robust construction make it an excellent choice for industrial automation projects that demand precision, safety, and ease of integration.
