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.
Control relay panel definition.
Use of control relay panel is not only limited in substations owned and operated by electrical utilities but also essential in.
Track light limiting panel.
A plc may be used to control the operation of a medium voltage motor perhaps 2 300v or 4 160v.
A relay is used to energize the starter which in turn switches the motor voltage while the plc controls the relay.
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.
Indications for the interlocks also will be there in control panel.

The control relay panels are designed manufactured as per voltage class of substations like 11kv 33kv 66kv 132kv 220kv and 400kv etc.
Control relays are an extremely important electrical part and they play a vital role in today s electronic devices.
Control panel works based on the plc dcs program or the relay logic.
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.
You can think of a relay panel kind of like a dispatch service.
The control relay panels are complete in themselves with all main and auxiliary relays annunciation relay fuses links switches wiring labels terminal blocks earthing.
However dc voltage or supply voltage may differ according to the panel requirement such as 30v dc 110v dc 220v dc etc.
A relay is an electrically operated switch it consists of a set of input terminals for a single or multiple control signals and a set of operating contact terminals the switch may have any number of contacts in multiple contact forms such as make contacts break contacts or combinations thereof.
Wired to provide a control sequence relays may also be used for simple control schemes where a plc would prove uneconomical.

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.
