Organize complex control logic with the 11-Pin Round Relay Base. This heavy-duty socket, often referred to as a PF113A base, is designed to house 11-pin octal-style relays, enabling the control of up to three independent circuits simultaneously (3PDT). Engineered for the demands of industrial electrical cabinets, this base provides a reliable, plug-and-play interface for your most critical switching components.
Multi-Voltage Compatibility: Designed to work seamlessly with a wide range of relay coils, including DC 12V, DC 24V, AC 110V, and AC 230V.
11-Pin Round Configuration: Specifically keyed for 3PDT (3 Form C) round-pin relays, ensuring correct orientation and secure electrical contact.
Heavy-Duty Screw Terminals: Features high-quality M3.5 screw terminals that provide superior clamping force for secure, low-resistance wiring.
Dual Mounting Options: Equipped with an integrated orange locking clip for standard 35mm DIN rail installation, plus built-in screw holes for direct surface mounting.
Fire-Resistant Housing: Constructed from premium, high-insulation materials to maintain safety and performance in high-temperature environments.
The 11-Pin PF113A Relay Base is the preferred choice for complex automation:
Complex Logic Circuits: Perfect for systems requiring 3PDT switching to manage multiple interlocking signals.
Industrial Machinery: Used extensively in manufacturing lines for motor sequence control and safety relays.
HVAC & Boiler Systems: Reliable mounting for AC 230V control relays in commercial climate systems.
Control Panel Building: A standard component for clean, professional, and maintainable electrical cabinet layouts.
Base Model: PF113A (Standard 11-Pin Round).
Supported Coil Voltages: DC 12V / DC 24V / AC 110V / AC 230V (Relay Dependent).
Can I use an 8-pin relay in this 11-pin base?
No. This base is specifically designed with an 11-pin circular layout. For 8-pin round relays, you must use the PF083A base series.
Is it difficult to replace the relay once it's installed?
Not at all. This base is designed for "plug-in" maintenance. You can swap out a failed relay in seconds without touching any of the screw terminal wiring.
Will the wires come loose over time?
The terminals use a rising-clamp screw design that maintains pressure even under moderate vibration, making it highly reliable for industrial environments.
