There are several types of electrician employment certificates for Dongguan 2016 Guancheng Electrician Training

Status relays are commonly identified with the letters <>. They are a kind of soft component in sequence control and are often used in conjunction with step sequence control instructions. If step sequence control instructions are not used, status relays can be used as auxiliary relays in ladder diagrams. The main types of status relays include initial status relays, zero return status relays, holding status relays, and alarm status relays. Programming languages can complete various control tasks. Drawing and writing ladder diagrams are different depending on the control tasks. However, these ladder diagrams are composed of arithmetic circuits, R arithmetic circuits, self-locking circuits, interlocking circuits, time circuits, branch circuits, etc. Made up of basic circuits.

Self-locking circuit is a circuit form commonly used in mechanical locking switch circuit programming. It refers to the input relay contact Point closure output relay coil is energized to control its output relay contacts to lock the input relay contacts. When the input relay contacts are disconnected, the output relay contacts can still maintain the output relay coil energization. Time circuit refers to a circuit form that is controlled by a timer for delay, timing and pulse, which is equivalent to the function of a time relay in an electrical control circuit. <>Time circuits commonly used in programming mainly include time circuits controlled by a timer, time circuits controlled by a combination of two timers, time circuits controlled by timers in series, etc.
