Relay unit Schneider Electric P1E two-input auxiliary relay module

Schneider Electric P1E two-input auxiliary relay module is a compact device for switching and isolating electrical control circuits. It provides two independent control inputs that operate internal relay contacts, enabling reliable signal transfer and circuit control in automation systems, building management, and control panels. The module is designed for integration into relay racks or equipment that requires compact switching elements and convenient external control of loads and signals.

Advantages

The module offers a compact form factor that saves panel space while providing two control inputs for flexible wiring configurations. It provides electrical isolation between control inputs and contacts, ensuring reliable switching and protection for sensitive control electronics. The construction supports typical industrial mounting and connection methods and is suitable for use in installations where predictable contact operation and straightforward wiring are required.

Suitable for

• Control panels and relay racks requiring space-efficient auxiliary contacts
• Building automation systems for switching signals and low-power circuits
• Industrial control applications where isolation between control and load is needed
• Retrofit projects that need compact relay modules for additional outputs

Key specifications

• Two independent control inputs for activating relay contacts
• Auxiliary relay contacts suitable for switching control and signal circuits
• Compact module size for installation in relay racks or control enclosures
• Designed for electrical isolation between control inputs and outputs

How to use

Install the module in a suitable relay rack or control enclosure following standard electrical installation practices. Connect the control signals to the two input terminals and wire the relay contacts to the circuits you intend to switch, ensuring correct polarity and rated voltages. Verify that the supply and load conditions match the relay contact ratings before energising. Test each input independently to confirm correct switching behaviour and proper isolation between circuits.

Usage recommendations

Use the module within the electrical ratings of the relay contacts and follow local wiring regulations. Where signal integrity matters, keep control wiring separate from high-power conductors and use appropriate cable routing and protection. Regularly inspect terminal connections for tightness and signs of wear in routine maintenance.
