Wondering how industrial processes run automatically and reliably? Meet the PLC : the brain behind modern automation!
A PLC (Programmable Logic Controller) is an industrial computer specifically designed to control machines and processes automatically. PLCs are robust, reliable and can be easily programmed for a variety of applications in industry.
PLC controller with modules JUMO variTRON 500
A PLC receives signals from sensors (such as temperature, pressure or level), processes them according to a preset programme and then controls actuators (such as motors, valves or lamps). This allows processes to run fully automatically, without human intervention.
In a nutshell:
PLCs consist of components such as:
Central processing unit (CPU)
Digital inputs
Analogue inputs
Digital outputs
Analogue outputs
Power supply module
Communication module
Memory

PLCs are used in almost all industries where automation plays a role, such as:
JUMO offers innovative PLC solutions that are easy to integrate into existing systems. Our controllers are user-friendly, reliable and feature the latest technologies in communication and integration.
A PLC is specially designed for industrial automation and is much more robust than a standard computer.
Yes, but knowledge of programming languages such as Ladder Diagram (LD), Functional Block Diagram (FBD, Instruction List (IL), Sequential Function Chart (SFC) and Structured Text (ST) is required. Feel free to contact us for explanation and support.
In complex industrial applications and production processes, it is advisable to use PLC technology. This is because PLCs work well with other systems such as PC;s, PAC;s (Programmable Automation Controllers) control equipment and HMI's.
Absolutely! PLCs are scalable and therefor suitable for both small and larger applicaions.
Choosing the wrong type of PLC controller for a particular application can lead to problems in interaction with other equipment or difficulties in installation in the machine, among other things.
Decide how many and which inputs/outputs you will use in your project, including whether they are analogue inputs (voltage or current), temperature or pulse inputs, and transistor or relay outputs.
Note: when you have chosen the right number of input/output circuits, add about 15%. This will avoid problems when the installation is expanded in the future.
