3022218 - IP67 Quick-Lock - Industrial EMC Shielded Stainless - Circular

Product Specification

Product Overview​

The Phoenix Contact ​3022218​ is a compact, high-reliability relay interface module designed for seamless integration into industrial control systems. Part of Phoenix Contact’s industry-leading RELAY series, this component ensures safe and efficient signal amplification between low-power control circuits and high-power loads. Its robust polycarbonate housing provides IP20 protection, safeguarding against dust and accidental contact, while the screw terminal design guarantees secure wiring connections. The module supports DIN rail mounting (EN 60715), enabling quick installation in control cabinets, motor control centers, and modular automation setups.

Engineered for versatility, the 3022218 is compatible with a wide range of relay and contactor configurations, making it ideal for applications requiring electrical isolation and signal conversion. Compliance with ​IEC 60947, ​UL 508, and ​RoHS/REACH​ standards ensures global applicability and adherence to environmental regulations. Its transparent cover allows for visual status monitoring, simplifying maintenance and troubleshooting in complex systems.

​Key Technical Parameters​

The 3022218 is defined by its precision-engineered specifications:

• ​Rated Voltage: 24–230 V AC/DC (control circuit) / 250 V AC (load circuit).
• ​Switching Current: 6 A (resistive load) / 3 A (inductive load), ensuring compatibility with motors, solenoids, and heaters.
• ​Contact Configuration: SPDT (1 Form C) contacts for flexible switching operations.
• ​Operational Temperature: -40°C to +70°C, suitable for harsh industrial environments.
• ​Isolation Voltage: 4 kV (between coil and contacts), providing robust electrical separation.
• ​Mechanical Life: 10 million switching cycles, guaranteeing long-term durability.
• ​Mounting: Compatible with ​35 mm DIN rails​ for tool-free installation.
• ​Safety Certifications: UL 508 (industrial control), CE, and cULus listed.

These parameters make the 3022218 ideal for interfacing PLCs, sensors, and low-voltage controllers with high-power industrial loads.

​Primary Applications​

The 3022218 is widely deployed in automation systems requiring reliable signal amplification and isolation:

• ​Motor Control Circuits: Interfaces PLC outputs with motor starters and contactors.
• ​HVAC Systems: Controls compressors, fans, and heating elements in building automation.
• ​Process Automation: Manages solenoid valves, pumps, and actuators in chemical or water treatment plants.
• ​Energy Management: Switches resistive or inductive loads in renewable energy systems (e.g., solar inverters).
• ​Safety Systems: Integrates into emergency stop circuits and safety relays for machinery protection.

Its compact design and high isolation voltage also make it suitable for railway signaling, packaging machinery, and semiconductor manufacturing, where space constraints and electrical noise are critical challenges.

​Competitive Advantages​

The 3022218 stands out through its blend of performance and user-centric design:

• ​High Switching Capacity: Handles inrush currents up to ​45 A​ (for 20 ms), protecting sensitive control circuits.
• ​Universal Voltage Support: Operates across a broad voltage range (24–230 V AC/DC), reducing inventory complexity.
• ​Tool-Free Mounting: DIN rail clip enables rapid installation and reconfiguration.
• ​Visual Status Indicator: Integrated LED (optional models) or transparent cover for real-time monitoring.
• ​Long Service Life: Gold-plated contacts minimize arc erosion, ensuring reliable performance over millions of cycles.

These features reduce downtime, lower maintenance costs, and enhance system scalability in dynamic industrial environments.

​Functional Features​

The 3022218 delivers advanced functionality for modern automation needs:

• ​Electrical Isolation: Prevents noise interference between control and load circuits, critical for signal integrity.
• ​Fail-Safe Design: Snap-action contacts ensure quick break-make transitions, reducing arcing risks.
• ​Modular Expandability: Daisy-chaining capability allows multiple modules to share a single DIN rail slot.
• ​Wide Compatibility: Works with Phoenix Contact’s SACC/SAC modular connector system for plug-and-play wiring.
• ​Custom Labeling: Write-on tabs for clear circuit identification and documentation.

Combined with Phoenix Contact’s rigorous quality control, the 3022218 is a trusted solution for engineers prioritizing safety, efficiency, and adaptability in industrial control systems.
