PM633 ABB 可编程逻辑控制器

PM633技术说明如下：

继电保护装置的试验项目分为两种形式进行开展，分别是诊断性试验和例行试验。

诊断性试验主要是在继电保护装置进行巡视或巡检过程中发现设备运行不正常、来自家族缺陷警告、连续长时间运行等情况下，为实现设备运行状态的进一步评估而采取的试验。

例行试验主要是指在设备保护停用状态下进行的各种试验。

PM633特点如下1：

控制执行器。可用于控制外部执行器或设备，如马达、阀门、蜂鸣器等，通过继电器输出信号来实现控制动作。

信号放大。可以放大控制系统的数字信号，以驱动继电器并控制大功率设备。

故障诊断。可能配备有故障诊断功能，可监测继电器状态，识别故障并报告给控制系统。

过载保护。可能具有过载保护功能，以保护控制系统和执行器免受过电流或过负荷的损坏。

The PM633 technical description is as follows:

The test items of relay protection devices are divided into two forms, which are diagnostic test and routine test.

Diagnostic tests are mainly tests taken to further evaluate the operating status of the equipment when the relay protection device is found to be running abnormally, warning of defects from the family, or running continuously for a long time during inspection or inspection.

Routine tests mainly refer to various tests carried out in the state of equipment protection.

PM633 features are as follows: 1.

Control the actuator. Can be used to control external actuators or equipment, such as motors, valves, buzzers, etc., through the relay output signal to achieve control action.

Signal amplification. The digital signals of the control system can be amplified to drive relays and control high-power equipment.

Fault diagnosis. May be equipped with a fault diagnosis function that monitors relay status, identifies faults and reports them to the control system.

Overload protection. Overload protection may be available to protect control systems and actuators from damage caused by overcurrent or overload.
