How to see the terminal block wiring diagram

The application of the terminal block is mainly embodied in the power electronic distribution line. When the equipment inside the screen is connected with the equipment outside the screen, some special terminal blocks must be passed. These terminal blocks are combined and called the terminal block. The function of the terminal block is to connect the devices in the screen with the lines of the off-screen devices, and play the role of signal (current and voltage) transmission. With the terminal block, the wiring is beautiful and easy to maintain, and the connection between the long distance lines is mainly firm, and the construction and maintenance are convenient.

Terminal block, commonly used English letters and numbers, or use Chinese pinyin letters plus numbers to indicate the current of the maximum connection point current of the terminal block, as well as the size and number of terminals of the terminal block, also used to indicate the manufacturer series The model number of the product.

How to look at the terminal block diagram? Where does the control line come from?

The terminal block is actually a professional terminal, which is convenient for maintenance. The line number of the terminal block is consistent with the line number of the control schematic. X0 terminal block number, where 1-13 is the terminal block serial number of the terminal block. The left column SA control switch, KM contactor, KA relay, 24V power supply, and PA are inputs. The right column 1007-PT- is the line number, RVV4*1.5 represents the cable 1.5 1.5 square, RVVP8*1.0 represents the shielding line 8 1 square line, and finally reaches the dcs control system; RVVP2*1 represents the shielded line two 1 square line to Level sensor (with positive and negative ends).

For the terminal: the sensor is the input line number, other signals may be fed back to the DCS, or it may be the DCS drive execution and indication
