eisco Demonstration Relay

This relay demonstration unit is ideal for teaching the principles of electrical circuits and control in science lessons. It clearly shows how a low voltage circuit can safely control a separate higher voltage circuit, making it perfect for practical classroom investigations. Suitable for secondary schools and colleges studying electricity and electromagnetism.

• Coil input: 4–6V DC

• Bulb input: Maximum 6V AC/DC

• Demonstrates separation of control and switched circuits

• Designed for clear visibility of components during demonstrations

• Supports hands-on learning in physics topics
