Function Of A Roof Control Relay

In electromechanical relays the coil accomplishes this function.

Function of a roof control relay.

The ac compressor relay is responsible for supplying power to the ac compressor and clutch. The control and the switch are electrically isolated from each other and they have their own voltage and current ratings requirements. The switch may have any number of contacts in multiple contact forms such as make contacts break contacts or combinations thereof. The control circuit functions as the coupling between the input and output circuits.

Some relays are used for the protection of the power system. Relays are normally used in the control panels manufacturing and building automation to control the power along with switching the smaller current values in a control circuit. A relay is a electromagnetic switch. Similarly they are used to control high current circuits with the help of low current signals.

They are used to time the delay open and delay close of contacts. The ocs hooks up to your wired lan router etc and provides a web site which can monitor control power heating and cooling systems lighting roll off roof dome shutter and also monitor weather conditions. Some of them are primary relay meaning that they are the first line of defence. Control and relay panel is most important equipment of the substation as it work as shield guard for all substation equipments and electrical network.

The control circuit is the part of the relay that determines when the output component is energized or de energized. Relays are used to control high voltage circuits with the help of low voltage signals. It consists of a set of input terminals for a single or multiple control signals and a set of operating contact terminals. You will also need to pull up on the emergency brake one click in order to activate the switch.

A relay is an electrically operated switch. There is also a poor man s version of this feature override. Its basic function is to allow a low power control voltage operate a high power switch. Relays are used to provide time delay functions.

Such relays sense the fault and send a signal to the proper circuit breaker to trip and clear the fault. The relay must come into action whenever there is a fault and must not operate if there is no fault.
