PILZ-680003--4869L4-+-4753L4 安全继电器

PILZ-680003--4869L4-+-4753L4 安全继电器是一种特殊的继电器，主要用于保护暴露于不同等级之危险性的机械操作人员。它的设计目标是实现正确且低误动作的继电器完整功能，以提高安全因素。

PILZ-680003--4869L4-+-4753L4 安全继电器由数个继电器与电路组合而成，以互补彼此的异常缺陷。当发生故障时，它会有规则地做出动作，具有强制导向接点结构。即使发生接点熔结现象，也能确保安全，这一点与一般继电器完全不同。

PILZ-680003--4869L4-+-4753L4 安全继电器是安全回路中所必须的控制部分，它接受安全输入，通过内部回路的判断，确定性的输出开关信号到设备的控制回路里。简单地说，安全继电器都是双通道信号型，只有两个通道信号都正常时，安全继电器才能正常工作；在工作过程中，只要其中任一通道信号断开，安全继电器都会停止输出，直到两个通道信号都正常且复位后才能正常工作。

此外，安全继电器还有以下几种类型：

热敏干簧继电器：一种利用热敏磁性材料检测和控制温度的新型热敏开关。它由感温磁环、恒磁环、干簧管、导热安装片、塑料衬底及其他一些附件组成。热敏干簧继电器不用线圈励磁，而由恒磁环产生的磁力驱动开关动作。恒磁环能否向干簧管提供磁力是由感温磁环的温控特性决定的。

固态式继电器：一种两个接线端为输入端，另两个接线端为输出端的四端器件，中间采用隔离器件实现输入输出的电隔离。

总之，PILZ-680003--4869L4-+-4753L4 安全继电器是为了保护人员和设备安全而设计的一种特殊设备。如需了解更多关于安全继电器的信息，建议咨询专业人士或查阅相关书籍文献。

The PILZ-680003- 4869L4-+ 4753L4 safety relay is a special relay designed to protect machine operators exposed to different levels of danger. It is designed with the goal of achieving the full functionality of the relay with correct and low error operation in order to improve the safety factor.

PILZ-680003--4869L4-+-4753L4 Safety relays are a combination of several relays and circuits to complement each other's abnormal defects. When a fault occurs, it will act regularly and has a forced guide contact structure. Even if the phenomenon of contact melting, it can ensure safety, which is completely different from the general relay.

PILZ-680003--4869L4-+-4753L4 Safety relay is the necessary control part of the safety loop, it accepts the safety input, through the judgment of the internal loop, deterministic output switching signal to the control loop of the device. Simply put, the safety relay is a two-channel signal type, only when the two channel signals are normal, the safety relay can work normally; During the working process, as long as either channel signal is disconnected, the safety relay will stop output until the two channel signals are normal and reset to work normally.

In addition, there are the following types of safety relays:

Thermal reed relay: A new thermal switch that uses a thermal magnetic material to detect and control temperature. It is composed of a temperature-sensing magnetic ring, a constant magnetic ring, a reed pipe, a heat-conducting mounting piece, a plastic substrate and some other accessories. Thermal reed relays do not use coil excitation, and the magnetic force generated by the constant magnetic ring drives the switching action. Whether the constant magnetic ring can provide magnetic force to the reed tube is determined by the temperature control characteristics of the temperature-sensing magnetic ring.

Solid-state relay: a four-terminal device with two terminals as input terminals and the other two terminals as output terminals, and an isolation device is used in the middle to achieve electrical isolation of input and output.

In short, the PILZ-680003- 4869L4-+-4753L4 safety relay is a special device designed to protect the safety of personnel and equipment. If you need more information about safety relays, it is recommended to consult a professional or consult relevant books and literature.
