Product Overview

Our 8-Pin Round Plug-In Power Relay is an industry-standard, heavy-duty electromagnetic switch designed for seamless automation and electrical control circuits. Housed in a robust, transparent polycarbonate casing for easy visual inspection, this relay features a standard 8-pin octal base that effortlessly plugs into standard DIN-rail sockets.

Engineered to handle versatile control configurations, it features a DPDT (2 Form C) contact structure, allowing you to manage two independent electrical circuits simultaneously.

Key Features & Benefits

• Multi-Voltage Coil Availability: Choose the exact power configuration required for your project:

  • 12V AC/DC (Ideal for automotive, low-voltage DIY, and small electronics)

  • 24V AC/DC (Standard for industrial automation and HVAC control panels)

  • 230V AC (Perfect for mains voltage switching and heavy electrical machinery)

• Double-Pole Double-Throw (DPDT / 2C): Controls two independent lines with both Normally Open (NO) and Normally Closed (NC) contacts for ultimate wiring flexibility.

• Transparent Protective Casing: Clear shell allows maintenance teams to instantly visually check contact conditions, coil status, and operational mechanical movement.

• 10A High Switching Capacity: Built with premium silver alloy contacts capable of handling inductive and resistive loads up to 10A safely.

• Plug-and-Play Maintenance: Features an 8-pin round (octal) plug base, allowing lightning-fast replacement without disconnecting any panel wiring.
