PLC类型

其中MR为继电器类型，MT为晶体管类型，它们的区别是:

1.继电器接的外部电源可以是直流也可以使交流，可直接驱动220v直流负载，晶体管的外部电源只能接直流的，不能直接驱动开关，需要接中继来间接驱动

⒉继电器类型的开关频率低，而晶体管可以输出高频信号如伺服系统的脉冲输出就使用晶体管类型的PLC。在实际运用中根据需要来选择相应的PLC规格。

PLC输出端子

以40端子来说明，输入3组+输出2组=5+40端子，其中输入端子只有一个公共端S/S，而输出有5个公共端。YO和Y1各单独使用com端，Y2和Y3共用con2，Y4、5、6、7共用com3，Y10、11、12、13共用com4，Y14、15、16、17共用com5。

GDD360C GDD360C-3BHE047217R0101模块是—种紧凑耐用的器件，可用于各种应用。它旨在在恶劣的工业环境中提供准确可靠的测量，使其成为石油和天然气，化学和发电行业使用的理想选择。

电流有两种方法，它们是直流电(DC)和交流电(AC).

与河流的流动相比，直流电是一种电流始终沿特定方向流动的方法。它是指从电池、蓄电池、太阳能电池等获得的电流流动。

另一方面，交流电(AC)是一种周期性地不断切换正负极的方法，电流的流动方向电量相应变化。这是从发电机或插座获得的电流。发电厂产生并输送到家庭的电力也以交流电的形式传输。在直流电中，电压总是恒定的，电流按一定方向流动。相反，在交流电中，电压周期性地由正变负和由负变正，电流的方向也相应地周期性变化。直流电源的特点

GDD360C-3BHE047217R0101 电流始终沿恒定方向流动的直流电具有以下优点和缺点。

优点

1、电路中没有提前或延迟2、不产生无功功率

3、可以蓄电

坏处

1、电流中断困难2、电压转换困难3、电解作用强

在交流电中，电流的方向是不断变化的。因此，例如，当电路中包含电容器或电感器时，流向负载的电流相对于电压行为会出现延迟或提前。

但是，对于直流电，电压和电流方向始终不变，因此电容器和线圈的行为也始终不变。因此，在直流中，电路中没有提前或延迟。

PLC type

Where MR Is the relay type, MT is the transistor type, their difference is:

1. The external power supply connected to the relay can be DC or AC, which can directly drive 220v DC load. The external power supply of the transistor can only be connected to DC, and can not directly drive the switch

The switching frequency of the relay type is low, and the transistor can output high frequency signals such as the pulse output of the servo system using a transistor type PLC. In the actual application according to the need to choose the corresponding PLC specifications.

PLC output terminal

To illustrate with 40 terminals, 3 groups of input + 2 groups of output =5+40 terminals, where the input terminal has only one common terminal S/S, and the output has 5 common terminals. Y2 and Y3 share con2, Y4, 5, 6, 7 share com3, Y10, 11, 12, 13 share com4, and Y14, 15, 16, 17 share com5.

The GDD360C GDD360C-3BHE047217R0101 module is a compact and durable device that can be used in a variety of applications. It is designed to provide accurate and reliable measurements in harsh industrial environments, making it ideal for use in the oil and gas, chemical and power generation industries.

GDD360C-3BHE047217R0101 Product parameters

- the input voltage: 24 VDC - input current: biggest 100 ma - output voltage: 4 ~ 20 ma - working temperature: - 40 ° ℃ ~ 85 ℃, storage temperature: - 40 ° ℃ ~ 85 ℃, humidity: 0-95%, no condensation

There are two methods of current, they are direct current (DC) and alternating current (AC).

In contrast to the flow of a river, direct current is a method by which the current always flows in a specific direction. It refers to the flow of electric current obtained from batteries, storage batteries, solar cells, etc.

Alternating current (AC), on the other hand, is a method of constantly switching between positive and negative electrodes periodically, and the flow direction of the current changes accordingly. This is the current obtained from a generator or socket. Electricity generated by power plants and delivered to homes is also transmitted in the form of alternating current. In direct current, the voltage is always constant and the current flows in a certain direction. In alternating current, by contrast, the voltage changes periodically from positive to negative and from negative to positive, and the direction of the current changes periodically accordingly. Characteristics of DC power supply

GDD360C-3BHE047217R0101 Direct current that always flows in a constant direction has the following advantages and disadvantages.

advantage

1, there is no advance or delay in the circuit 2, no reactive power generation

3, can store electricity

disadvantage

1, current interruption is difficult 2, voltage conversion is difficult 3, electrolytic effect is strong

In alternating current, the direction of the current is constantly changing. Thus, for example, when capacitors or inductors are included in the circuit, the current flow to the load will be delayed or advanced in relation to the voltage behavior.

However, for direct current, the voltage and current direction are always the same, so the behavior of the capacitor and coil is always the same. Therefore, in DC, there is no advance or delay in the circuit.
