About This Product

With this unit, it is easy to see that the circuit powering the relay coil is completely separate from the circuit the relay switches on. That separation is one of the reasons relays are used where a safe low voltage circuit controls a high voltage circuit. The Demonstration Relay is available for supply within India and for export to Portugal, Malta, Bolivia, Afghanistan, Albania and Central African Republic.

Frequently Asked Questions

Q1. Why are relays used to control high voltage circuits?
The circuit powering the coil is completely separate from the switched circuit, so a safe low voltage circuit can be used to control a high voltage circuit.
