Tianjin Control Cabinet Direct Start, Precise Dimensions

The distribution panel primarily consists of switches, responsible for power distribution and circuit protection, etc.

The control cabinet primarily serves to implement various control functions, typically containing switches, relays, or PLCs.

The control cabinet is primarily used for high-rise building water supply without towers and fire-fighting deep well pump constant pressure water supply, etc. It is designed for situations that require closed-loop adjustment of pump speed based on real-time water usage conditions. It incorporates a closed-loop control system consisting of a well-known brand variable frequency inverter, intelligent controller, pressure sensor, and pump.

Multiple-pump control ensures stable pipeline pressure, improves water supply quality, reduces secondary pollution, boasts high energy-saving efficiency, and can achieve an unmanned water supply automatic control system without a tower.

The Function of Electrical Control Cabinets:

The electrical control cabinet, as the name implies, is an electrical cabinet used for electrical control purposes.

Relay

PLC instructions can be directly sent to the control loop, but they may also be relayed through a relay first. To illustrate, if your PLC's output port is 24VDC, but the control loop diagram requires a 220VAC supply node from the PLC, you will need to add a relay to the PLC output port. This means that when the instruction is sent, the relay operates, and then the control loop node is connected to the relay's normally open or normally closed contact. Whether to use a relay is also determined by the specific situation.
