On the primary side of the high voltage transformer.
The outlet would be the more often recommended place for it.An electrical timer can be placed anywhere within the circuit. Usually the timer would be placed at the front end of the circuit.
an oscillating RC circuit
Timer relays are used in control circuitry. There are two main types, an (off delay) and an (on delay). If you want one device to turn off before the timer controlled device then you would use an off delay timer. If you want one device to turn on before the timer controlled device then you would use an on delay timer. When the timer is energized this starts the timer circuit in the relay to time out.
A timer is often used in a heated rear window function to stop the circuit from over heating and blowing a fuse if forgotton about.
Do a google search for: 555 timer circuit You will find hundreds of circuits you can use.
The wattage rating of a timer is governed by the manufactures specification. As long as the light bulbs wattage rating is not higher than the timers rating, the timer will be alright to use in the circuit. The circuits load is what governs the wattage of the circuit.
It is not possible to have a turbo timer hold open a circuit on a BA Falcon and still be able to use the keyless remote. The turbo timer must be on a close circuit at all times for keyless remote to operate.?æ
It sounds to me like the exhaust timer is just a switch. The 20 amp rating that the timer is given is the maximum amount of current that it can handle and still be within its safety specifications. It will work very well on a 15 amp circuit.
the watchdog timer is a circuit that will simply time out sending an alert telling peripheral devices that data is incorrect or at least non reliable
A modern X-ray machine is turned on-and-off by a timer-operated electrical switch. The power is turned on when the operator presses a start button and is turned off automatically by the timer. This is done to reduce the likelihood of operator error.
The timer has to be multi-pole. The ballast must be connected to the load contacts of the timer. If the timer is a 120 Volt timer, the timer has to run on a 120V. circuit. Loads are loads, and as long as you have a multi-load timer you can hook up whatever you want. If the timer only works on a shared power source (load shares the timer supply) you will need to use a contactor on the load side or the timer.
R (resistance) and C (capacitance).
