Terminal block wiring is an electrical component used to connect lines. It is mainly used in electrical equipment. It connects the lines of the equipment in the screen and the equipment outside the screen, which plays a role in signal (current and voltage) transmission, and also allows wiring It looks beautiful and is convenient for maintenance, construction and maintenance. It is estimated that many people don't know how to look at the terminal block wiring diagram. Below, Tang Hongsen will share with you how to look at the terminal block wiring diagram.

Wiring terminal blocks, commonly used English letters and numbers, or Chinese pinyin letters and numbers, are used to indicate the current flow of the maximum connection point of the terminal block, as well as the size and number of terminals of the terminal block. It is also used to indicate the manufacturer series. The model of the product, the wiring terminal is actually a professional terminal, which is convenient for maintenance. The wiring number of the wiring terminal and the wiring number of the control principle diagram correspond to the same. X0 wiring board number, where 1-13 is the terminal number of the wiring board group. The left column SA control switch, KM contactor, KA relay, 24v power supply, PA is the input terminal. The right column 1007-PT- is the wire number, RVV4*1.5 represents the cable 4 pieces of 1.5 square, RVVP8*1.0 represents the shielded wire 8 pieces of 1 square wire, and finally to the DCS control system; RVVP2*1 represents the shielded wire two pieces of one square wire to the Liquid level sensor (with positive and negative terminals). For the terminal: the sensor is the input line number, and other signals may be fed back to the DCS, or it may be the execution and instruction of the DCS drive.

Terminal block wiring function: 1. Beautiful. Because the terminal block separates the inner part of the control circuit from the door part, it looks neat and tidy, so that the control circuit is not as messy as a spider web. 3. Convenient for maintenance. If there is a problem in the use process, you can directly use the meter to measure the voltage of the corresponding limit terminal on the terminal block to quickly find the fault (of course, the 220V control loop is much easier to check than the 380V control loop), and it is easy to check the line because There will be terminal numbers on the terminal block, and the corresponding numbers are generally connected to the corresponding contacts in the control loop. 4. Convenient to install remote control. Because the remote control can be wired directly from the terminal block, there is no need to modify the original control loop.

The above is the viewing method of the terminal block wiring diagram and the introduction of the terminal block wiring function. The terminal block is used to facilitate the connection of the wires. It is actually a piece of metal enclosed in insulating plastic, with holes at both ends for insertion. For wires, there are screws for fastening or loosening. With terminal block wiring, it is convenient for wiring, and for checking wires; and for node expansion, it provides great convenience to our lives.
