Control relay panel definition.

Instruments are normally connected to control panel. Control relays are an extremely important electrical part and they play a vital role in today s electronic devices. A relay is used to energize the starter which in turn switches the motor voltage while the plc controls the relay. Relay panels lighting products.

Wired to provide a control sequence relays may also be used for simple control schemes where a plc would prove uneconomical. However dc voltage or supply voltage may differ according to the panel requirement such as 30v dc 110v dc 220v dc etc. The control relay panels are complete in themselves with all main and auxiliary relays annunciation relay fuses links switches wiring labels terminal blocks earthing. A control relay is in essence a switch that is controlled by electrical current a control relay is an electrical component that opens or closes a switch in order to allow current to flow through a conducting coil with the coil not coming into direct contact with the switch.

You can think of a relay panel kind of like a dispatch service. The control relay panels are designed manufactured as per voltage class of substations like 11kv 33kv 66kv 132kv 220kv and 400kv etc. Use of control relay panel is not only limited in substations owned and operated by electrical utilities but also essential in. A plc may be used to control the operation of a medium voltage motor perhaps 2 300v or 4 160v.

Relays are used where it is necessary to control a circuit by an independent low power signal. In turn a relay panel is a panel that holds one or more relays that sends power or signal to equipment based upon the input received. A relay is basically another word for a switch. It could be a switch that turns something on off or a switch that alternates between two items.

Control relays and timers whether you re a machine builder or end user control panel designer or facility maintenance manager eaton s expansive offering of relay options with customization capabilities can meet your specific application requirements. A control relay panel is designed to provide to control the associated line or transformer through outdoor switchgear at various 11kv and 33kv zonal substations. Track light limiting panel.
