EISCO DEMO RELAY SWITCH , Each

Details:

The Relay Demonstration Unit enables the clear and practical investigation and study of relay function. A useful feature of this unit is that it clearly shows the circuit powering the coil to be completely separate from the circuit switched on by the relay. This is one reason relays are used where a safe low-voltage circuit can control a high-voltage circuit. The unit has a 4-6V DC coil input and a maximum 6V AC/DC bulb input.
