Industrial Control Panel Basics

hi I'm Josh bloom welcome to another video and the RSP supply education series today we're going to be talking about industrial control panels what they are why we use them and lastly all the different components located within the panel and what their purpose is let's first talk about what an industrial control panel is an industrial control panel is a collection of electrical components that are used to monitor and control industrial devices in industrial applications for example the panel we have here today is being used in a pumping facility for a local city so as you can imagine it monitors things like pressure within a pipe or flow it might send a signal to open or close a valve now that we've talked about what control panels do and why we use them let's talk about all the different components within the panel itself and what their purpose is now let's look at some of the components located within the actual panel itself first we're going to start with our main breaker where this is located is actually very important we want to think about where power is going to be coming into our enclosure power typically comes in at the top of the enclosure so we typically like to locate our main circuit breaker at the top of the enclosure either on the left side or the right side we typically see these mounted on the left side this breaker will kill power to everything located within the panel next we have a surge suppressor the cert suppressors function is to provide protection against a lightning strike or a power surge it will protect all the components downstream located in the panel itself moving on we have our AC power distribution this is simply where we bring AC power from our main breaker over to this bank of circuit breakers we have one wire coming in and it connects all these circuit breakers with this jumper bar here we then send power AC power in this case to the components that require AC power within this panel one component that requires AC power is our power supply now the power supplies function is to change one type of power to another type of power in this case the power supply takes 120 AC voltage and converts that to 24 volts DC voltage which is the voltage that's required for the majority of the components within our control panel from this power supply we send our DC voltage to our DC power distribution just like with our AC power distribution the DC power has one wire coming in connects these three circuit breakers together with a jumper bar and distributes that DC power to the components within our control panel moving on we're now going to talk about the Ethernet switch much like you might see at home or in your place of business the Ethernet switch simply allows the devices within the panel to communicate with one another using either a cat 5 or cat 6 cable next we want to talk about our radio the radio takes the data that come from the control panel transmits that data and sends it to another location that might be located far away the radio is typically paired with a poly phaser which provides lightning protection as well as an industrial radio antenna now let's talk about the brains of the operation the plc or a programmable logic controller the purpose of the plc is to send and receive data to the instruments that are wired in the field it takes that data with varying signal types translates it so that we can understand it and incorporate that into our distributed control systems now let's talk about the terminal blocks the terminal blocks are the connection point which field instruments are wired into our control panel depending on the instrument we have varying types of signals here we have our analog signals analog signals measure a range of values such as a tank level or water pressure here we have the terminal blocks that measure our digital signals digital signals are either on or off an example of this might be a valve is either open or closed lastly we have this Bank of relays that controls our digital outputs the digital outputs allow us to control higher voltage circuits while using lower voltage signals it also protects the plc for overcurrent as you can see we have a lot of different components all of these components are mounted to dinner rail and are surrounded by wire ducting for more information on din rail and wired ducting please refer to our other video at RSP supply comm all of the components within the panel including the wire ducting and din rail are mount to what we call the back plate the back plate is separate from the actual electrical enclosure itself and what the back plate allows us to do is fabricate build and wire this panel separate from the enclosure when we're ready we can take the back plate and all the attached components and put it in the electrical enclosure itself the electrical enclosure provides protection for both the components and any operators in the area it is common to make modifications to electrical enclosures one common modification is to mount what we call an HMI to the door the enclosure HMI stands for human machine interface it allows us to view and manipulate the data being sent and received by the PLC as you can see there's a lot that goes in to the design and fabrication of an industrial control panel however this is just one variation of thousands of different ways that we can build and fabricate control panels for a full line of industrial control panel components or thousands of other products please go to our website for more information or other educational
