24V Sugar Cube Relay

24V Sugar Cube Relay is a compact electromagnetic switch designed for switching AC or DC loads using a low-power 24V control signal. Commonly used in home automation, control systems, and industrial equipment, this relay offers reliable switching in a small form factor known as the “sugar cube” due to its size and shape.

Key Features:

• 24V Coil Voltage: Operates efficiently with 24V DC trigger signal.
• Compact Size: Sugar cube design fits easily on PCBs or control panels.
• High Load Capacity: Typically supports up to 10A at 250VAC or 30VDC.
• SPDT/SPST Configuration: Available in both single pole single throw and single pole double throw options.
• Isolation: Electrically separates control circuit from load circuit.
