PILZ-680003–4869L4-+-4753L4 安全继电器模块

PILZ-680003–4869L4-+-4753L4是一款安全继电器是由数个继电器与电路组合而成，目的是要互补彼此的异常缺陷，达到正确且低误动作的继电器完整功能，使失误和失效值降低，安全因素则提高。这样的设计是为了保护暴露于不同等级危险性的机械操作人员。

安全继电器并不是“没有故障的继电器”，而是发生故障时做出有规则的动作。它具有强制导向接点结构，即使发生接点熔结现象时也能确保安全，这一点同一般继电器完全不同。安全继电器是一个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。

PILZ-680003–4869L4-+-4753L4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。

PILZ-680003–4869L4-+-4753L4的主要目标是保护机械操作人员，避免因机械故障或误操作导致的事故。在紧急停止解除时，机器不能出现突然再启动，这是安全继电器的一个重要特性。

总的来说，PILZ-680003–4869L4-+-4753L4器是一种特殊类型的继电器，它设计用于在发生故障时做出有规则的动作，以保护机械操作人员免受伤害。其双通道信号特性确保了在任一通道信号异常时，继电器都能停止输出，从而提高了系统的安全性。

PILZ-680003–4869L4-+-4753L4 is a safety relay which is composed of several relays and circuits to complement each other’s abnormal defects and achieve the complete function of the relay with correct and low error operation, so that the error and failure value is reduced, and the safety factor is increased. This is designed to protect machine operators who are exposed to different levels of risk.

Safety relays are not “fault-free relays”, but make regular actions when a fault occurs. It has a forced guide contact structure, even if the contact fusion phenomenon can ensure safety, which is completely different from the general relay. The safety relay is the necessary control part of a safety loop, which accepts the safety input and deterministic output switching signal to the control loop of the device through the judgment of the internal loop.

PILZ-680003–4869L4-+-4753L4 are dual-channel signal type, only when the signals of both channels 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.

The main objective of the PILZ-680003- 4869L4-+ 4753L4 is to protect machine operators from accidents caused by mechanical failure or misoperation. It is an important feature of the safety relay that the machine cannot suddenly restart when the emergency stop is lifted.

In general, the PILZ-680003- 4869L4-+ 4753L4 is a special type of relay designed to make a regular action in the event of a failure in order to protect the mechanical operator from injury. Its dual-channel signal characteristics ensure that the relay can stop output when either channel signal is abnormal, thus improving the security of the system.
