Function Of A Roof Control Relay

A relay is a electromagnetic switch.

Function of a roof control relay. 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. A relay is an electrically operated switch. 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. Its basic function is to allow a low power control voltage operate a high power switch.

Relays are used to provide time delay functions. By removing one of the pins on the factory convertible top relay you can override the speed control limiter and open the roof while driving. They are used to time the delay open and delay close of contacts. Moreover these panels are useful to control the flow of electricity as per the voltage class and detect the faults in transmission lines.

The switch may have any number of contacts in multiple contact forms such as make contacts break contacts or combinations thereof. There is also a poor man s version of this feature override. It consists of a set of input terminals for a single or multiple control signals and a set of operating contact terminals. Without this relay the ac compressor will not have power and the ac system will not function.

The control circuit is the part of the relay that determines when the output component is energized or de energized. You will also need to pull up on the emergency brake one click in order to activate the switch. The control and the switch are electrically isolated from each other and they have their own voltage and current ratings requirements. In electromechanical relays the coil accomplishes this function.

The relay must come into action whenever there is a fault and must not operate if there is no fault. The control circuit functions as the coupling between the input and output circuits. Such relays sense the fault and send a signal to the proper circuit breaker to trip and clear the fault. 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. Some relays are used for the protection of the power system.
