Q.construct a ladder diagram for automatic level control of on roof reservoir for the following two condition.
1)whan water level is below the lower level,switch of the pump should turn on.
11) when water level touches the upper level,the pump should turn off ;it should remain off until the water level reaches below the lower level .
The automatic combustion control, or ACC, of boilers designed for shipping, is a unit that contains a programmable sequence control to operate the pilot burner, furnace purge, and the burner piston valve. It also transmits the automatic adjustment commands for the correct combustion of air quantity and fuel oil quantity.

An electronic programmable thermostat has a printed circuit board on which is mounted a chip one or more relays LCD display terminal strip sometimes a backup battery
The signal is changed to dc in the AGC circuit to change the gain. A weak signal will increase gain.
The disadvantage of automatic gain control, attenuating even the weak signal, is overcome by the use of delayed automatic gain control (dagc).
A dedicated logic circuit is generally used to perform one task. Not usually programmable. Say for example a lift (elevator) control; where inputs are received from the lift position, door position, floor etc and logic outputs to motors etc from the logic performed.
Vizio VUR5 is one of the best universal programmable remote control, it's better than Vizio VUR6. So your best choice is a VUR5 if you want a universal remote.
The Honeywell EConnect RedLINK wireless thermostat control system is a good programmable Internet thermostat that will work with baseboard heaters. It allows you to control up to eight separate baseboards.
mostly Automatic machines are based on the PLC(programmable Logic Control) or other core controller. the best example of this kinda machines is CNC. in this the actuators or motors or any mechanical component is controlled by the relay or solenoids or solid state relay. this is all done step by step as per step sequence is stored in program. and by this program machine work in loop. and act as Automatic.
An automatic curtain operator is a device that enables the automated opening and closing of curtains or drapes, often through remote control, timers, or smart home integration. These systems can enhance convenience and energy efficiency by allowing users to control light and privacy without physical effort. They can be powered by electricity or batteries and may include features such as programmable schedules and integration with home automation systems. Automatic curtain operators are commonly used in residential, commercial, and hospitality settings.
