Question

7. Given a temperature control application where if the temperature at a sensor becomes closed when the temperature is below 55°F. Use a 15 minute timer/delay relay to keep the heater coiron once the temperature is below 55°F. Write a ladder logic program to achieve this Temp switch Timer 15 min Keep output high for 15 min once activated Heater Coil Turn on to increase temperature Closed if <55 F g 1 input switch (push button), write a plc ladder logie program to control 3 ights I comes on for 1 second, then light 2 for 2 seconds and 8. Usin When switch is closed: light then light 3 for 3 seconds. Use delay relay

Answer 1

The given data is sequence of operators here x_1 is switch to check temperature as output (i) less that 55 degree F T_1 lessthanorequalto 55 degree F and T_1 are input to timer T on with delay present = 15 m and take T on input to the heater we will CHCL this is the required solution for given data
