Terminal Blocks Defined

Terminal blocks are insulated, modular connectors that are designed to connect different circuits together. These components are also referred to as terminal connectors or connection terminals. Terminal blocks generally appear as a long strip made up of several individual terminals, hence the name.

Industrial Control Basics: Part 6 – Wire & Cable Management

Industrial control panels comprise of control circuits, power circuits, or a combination of both. These circuits generate signals that control the performance of equipment or machinery connected to them. Wires and cables are integral to these circuits, and they play a significant role in their functioning. Trends such as maximum efficiency, minimal downtimes, quick turnaround times, and time-to-market capabilities are critical to industrial users.

The Basics of a Terminal Block

Terminal blocks are insulated, modular connectors that are designed to connect different circuits together. The terminals serve different functions, such as they can be used to ground the wires, or connect outlets, as well as electric switches to the mains, in the presence of the electrical power. Terminal blocks are found on a variety of power management and industrial devices including motor protection relays, variable frequency drives, power supplies and connectors, programmable logic controllers, traffic controls, and so on.
