PLC control cabinet

1. Overview

PLCA control cabinet refers to a programmable control cabinet, which is a complete set of electrical cabinets that can control motors and switches.PLCControl cabinets can adapt to industrial automation control scenarios of various sizes and scales, and are widely used in industries such as power, metallurgy, chemical, papermaking, and environmental wastewater treatment. Typical applications include constant pressure water supply, air compressors, fans and pumps, central air conditioning, port machinery, machine tools, boilers, papermaking machinery, food machinery, etc.

2. Main features

PLCThe control cabinet generally includes the following five parts: air switch PLC、 Power supply, relays, and wiring terminals. The PLC integrated control cabinet has protection functions such as overload, short circuit, and phase loss protection. It has a compact structure, stable operation, and complete functions. It can be combined according to the actual control specifications, which can achieve automatic control of a single cabinet or form a distributed control system (DCS) through industrial Ethernet or industrial fieldbus networks for multiple cabinets.

Power supply: DC24V; Single phase AC 220V, (-10%,+15%), 50HZ

Protection level: IP41 or IP20

3. Environmental conditions

• The ambient temperature should be between 0 ℃ and 55 ℃ to prevent direct sunlight exposure;
