GE104X125DC014  状态继电器 用于在电路中实现状态的存储和控制

GE104X125DC014 状态继电器（State Relay）是一种电子元件，用于在电路中实现状态的存储和控制。它通常由一个电磁线圈和一组触点组成，可以根据线圈的激励状态改变触点的开合状态。

GE104X125DC014 状态继电器的主要作用是在电路中存储和保持某个状态，直到另一个信号或条件触发其改变。它可以用于控制电路的逻辑顺序、实现记忆功能、进行状态监测等。

GE104X125DC014状态继电器通常具有多个触点，可以根据不同的状态组合实现不同的控制功能。例如，在一个简单的控制电路中，状态继电器可以用来控制电机的启动、停止和反转。

GE104X125DC014状态继电器在工业控制、自动化系统、电力电子、通信设备等领域广泛应用。它们提供了一种可靠、高效的方式来实现电路的状态控制和逻辑操作。

状态继电器是PLC在顺序控制系统中实现控制的重要内部元件。它与后面介绍的步进顺序控制指令STL组合使用，运用顺序功能图编制高效易懂的程序。状态继电器与辅助继电器一样，有无数的动台触点和动断触点，在顺控程序内可任意使用定时器在PLC中相当于一个时间继电器，它有一个设定值寄存器(一个字)、一个当前值寄存器(字)以及无数个触点（位)。对于每一个定时器，这三个量使用同一个名称，但使用场合不一样，其所指的也不一样。通常在一个可编程控制器中有几十个至数百个定时器，可用于定时操作。

The GE104X125DC014 State Relay is an electronic component used to store and control state in a circuit. It is usually composed of an electromagnetic coil and a set of contacts, and the opening and closing state of the contacts can be changed according to the excitation state of the coil.

The main role of the GE104X125DC014 status relay is to store and hold a certain state in the circuit until another signal or condition triggers it to change. It can be used to control the logic sequence of the circuit, to realize the memory function, to monitor the state and so on.

The GE104X125DC014 status relay usually has multiple contacts, which can realize different control functions according to different state combinations. For example, in a simple control circuit, a status relay can be used to control the start, stop, and reverse of a motor.

GE104X125DC014 status relay is widely used in industrial control, automation system, power electronics, communication equipment and other fields. They provide a reliable and efficient way to implement state control and logical operation of circuits.

Status relay is an important internal component of PLC in order control system. It is used in combination with the step sequence control instruction STL, which is introduced later, and uses the sequence function diagram to compile efficient and easy to understand programs. The status relay, like the auxiliary relay, has countless moving station contacts and breaking contacts, and the timer can be used arbitrarily in the sequential control program. It is equivalent to a time relay in the PLC, which has a set value register (a word), a current value register (word) and countless contacts (bits). For each timer, these three quantities use the same name, but the use of different occasions, its reference is not the same. There are usually dozens to hundreds of timers in a programmable controller that can be used for timing operations.
