Mar 10, 2022 · A PLC is an industrial-grade digital computer designed to perform control functions—especially for industrial applications. The majority of PLCs today are modular, allowing the user to add an assortment of functionality including discrete and analog inputs and outputs, PID control, position control, motor control, serial communication, and ...

Sep 27, 2022 · This article will go deeper into some control panel design concepts, focusing on standards and regulations and some of the industry's best practices, including NFPA 70 and 79, IEC/ UL 60947-4-1, and UL 508. Figure 1. An industrial control panel is at the core of a control system, containing electrical and control devices. Image used courtesy of ...

A programmable logic controller or PLC is a general-purpose controller, applicable to many different types of process control applications. The word “programmable” in its name reveals just why PLCs are so useful: the end-user is able to program, or instruct, the PLC to do virtually any control function imaginable.

Jan 10, 2024 · A complete guide to wiring PLC and remote I/O modules for inputs and outputs, whether they are AC, DC, or relay, with either sourcing or sinking operation. Figure 1. Wiring diagram for PLC modules and remote I/O terminals. Click on the image to see a high-res (printable 11x17 size) version.

Jan 15, 2024 · For these situations, the circuit schematic can be useful. Usually, we find only the most relevant sections of a circuit highlighted for our benefit in a user manual. Such is the case in a PLC I/O module, where only enough information is provided to see the interaction from the optocoupler to the crowbar circuit, and finally to the output MOSFET.

In every circuit formed by the output channel of a PLC driving a discrete control device, or by a discrete sensing device driving an input channel on a PLC, one element in the circuit must be sourcing current while the other is sinking current. An engineering colleague of mine has a charming way to describe sourcing and sinking: blowing and ...

Mar 26, 2023 · The subject of grounding in electronics is broad and complex, spanning across a variety of functions and objectives. In this article, we will investigate the applications and regulation of grounding in control systems on a fundamental level.

Mar 31, 2021 · Any control panel with a well-designed power protection framework will include an uninterruptible power supply (UPS) as its key component. Server rooms, industrial PCs, mobile applications (stacker cranes, AMR's), and others may also include a UPS. Features such as overall dimensions, power capacity, and switching time vary depending on the ...
