What is rack and chassis in PLC?

PLC rack or chassis is a hardware assembly that plugs communicating modules together (like input, output, CPU, power supply, communication, and additional function modules) in a single frame. With the help of rack and chassis, modules can be easily communicated to the other connected modules in the PLC system.

What is a PLC rack?

The rack serves as the backbone of the modular PLC system synchronizing both power and signal communication. It holds together the individual modules within a PLC like the CPU, Communication and Power supply. Amphenol provides valuable solutions that help attach each PLC component to the rack. …

What is the slot and rack in PLC?

A typical PLC has room for several I/O modules, allowing it to be customized for a particular application by selecting the appropriate modules. Each slot in the rack is capable of accommodating any type of I/O module. The I/O system provides an interface between the hard- wired components in the field and the CPU.

Where are rack PLCs used?

Rack-mounted PLCs are often used in complex applications where many inputs and outputs are required, such as large process control systems in the manufacturing sector. The speed of a PLC is mainly governed by the clock supplied to the CPU (processor).

What is a rack chassis?

A server chassis is a metal structure that is used to house or physically assemble servers in various different form factors. A server chassis makes it possible to put multiple servers and other storage and peripheral equipment in a single physical body.

What are components of PLC?

Programmable Logic Controllers have three components. These three PLC components are: processor, power supply, and an input/output (I/O) section. The processor, or the brain of the PLC system, is a solid-state device designed to perform a wide variety of production, machine tool, and process-control functions.

What is rack mounted?

A rack mount is a description of a hardware device capable of being mounted in a special rack or the actual rack. Rack mounting is commonly used with large companies to hold their network servers, routers, switches, or other network devices.

What is a brick type PLC?

The single-box type (or, as it’s sometimes called, a brick) is commonly used for small programmable controllers and is supplied as an integral compact package complete with power supply, processor, memory, and input/output units.

What is the difference between a server and a rack?

Unlike traditional servers that look much like a PC, a rack server is wider. So it can be secured into the rack using mounting screws or rails, depending on the design. If you only require a small number of servers, they are the best choice economically due to the lower upfront costs.
