PLC control cabinet

PLC control cabinet is an electrical cabinet with PLC controller as the core control unit, integrating electronic components such as touch screen, power supply and circuit breaker. Customize design according to engineering technical requirements to achieve equipment automation and process automation control.

The PLC control cabinet generally includes the following five parts:

circuit breaker

A general air switch, which is the power control for the entire cabinet.

PLC

This should be selected according to the needs of the project. For example, if the project is small, it can be directly an integrated PLC, but if the project is large, it may require modules, card type, and redundancy (that is, two sets of alternating use).

power supply

A 24VDC switching power supply, most PLCs come with a built-in 24VDC power supply, and whether to use this switching power supply depends on whether it is truly needed.

relay

Generally, PLCs can directly send instructions to the control circuit, but they may also be relayed by relays first.

terminal block

The PLC control cabinet has protection functions such as overload, short circuit, and phase loss protection. It has a compact structure and stable operation. It can be combined according to the actual control scale, which can achieve automatic control of a single cabinet or form a distributed control (DSC) system through industrial Ethernet or industrial fieldbus network for multiple cabinets. PLC control cabinets can adapt to industrial automation control scenarios of various sizes and scales. Widely used in industries such as power, metallurgy, chemical, papermaking, and environmental wastewater treatment.
