Introduction and features of the terminal block
Terminal Blocks This standard specifies various methods for identifying the terminals of electrical equipment (hereinafter referred to as equipment). The terminals and the general rules for identifying the terminal blocks of the equipment and the specific conductor ends by an alphanumeric system are established. This standard applies to the identification of the terminals of devices (such as resistors, fuses, relays, contactors, transformers, rotating electrical machines, etc.) and combinations of these devices, as well as for the identification of specific wire ends. Where necessary, the detailed application of these general rules for certain products and the necessary auxiliary identification methods can be given in the relevant standards.
The terminal block utilizes the existing rail-type terminal terminal UK connection technology, and is equipped with a circuit composed of electronic components, and the terminal block realizes the transmission coupling of the photoelectric process. The core of automatic control is that the control unit must be reliably isolated from each sensor and actuator to avoid interference. The optical isolation terminal can do this well and ensure that the field signal matches the low voltage required by the electronic control unit. It can also be used as a interface component between process control peripherals and control, signal and regulator devices, and for different voltage and power ranges.
Terminals can identify device terminals and specific wire ends using one or more of the following methods. 3.1 Terminals Use the marking system of the relevant product to determine and identify the actual or relative position of the equipment terminals or specific wire ends. 3.2 Use the marking system of the relevant product to determine and identify the color markings of the device terminals and the specific wire ends.
