Execution of Digital Logic Circuits

A safety circuit is employed on a lathe to prevent the motor turning if it is not safe to operate. A series of 2 switches are used to check end stop position and the presence of a safety guard.

a) Illustrate how a simple switch can be used to generate logic level voltages

b) Design a digital TTL Circuit using 2 input NAND gates to control the motor power relay and draw the schematic diagram .

c) Describe the operation of the circuit

d) Illustrate how this circuit can be connected to the existing transistor switched relay.

e) Build and test your circuits
