Programmable Logic Controllers (PLCs) are commonly used for which application?

Programmable Logic Controllers (PLCs) are particularly well-suited for applications that require automation, sequencing, and control of industrial processes. In the context of conveyor sequencing, PLCs play a critical role as they can be programmed to manage the precise timing and control of conveyor systems, ensuring that materials or products efficiently move along a production line. This involves coordinating multiple inputs and outputs to manage the operation of the conveyors, such as starting and stopping motors based on product presence or operational conditions.

While limit switches and temperature readings might be monitored or controlled within a PLC system, they are typically features or parameters of a broader application rather than standalone applications for PLCs. Similarly, while boiler safety systems can benefit from PLC integration for monitoring and safety interlocks, the most characteristic and classical application of PLCs is seen in the control and sequencing of mechanical systems, which is exemplified by conveyor systems.
