产品描述

plc开关量输出类型大致分为三种,继电器输出型、晶体管输出型和可控硅输出型. R-继电器；T-晶体管

继电器输出交流直流都可以,晶体管常见有5vdc和24vdc输出,可控硅比较少见,只有特殊输出型号才有.

考虑选用的输出模块类型,通常继电器输出模块具有价格低、使用电压范围广（可接市电）、负载能力大，导通压降小,承受瞬时电压和过电流的能力较强,但寿命短、响应时间较长、动作速度较慢等.

晶体管输出（可分PNP、NPN型）优点是通断速度快（脉冲输出，适合高频），一般为0．2ms左右；寿命长；缺点是工作电压低（不能接市电）；负载能力弱，300mA左右。

可控硅输出模块适用于直流负载,开关频繁,反应速度快,寿命长,电感性低功率因数负荷场合,但价格较贵,过载能力较差.

PLC有三种输入类型。一是直流输入，一般为DC24V或DC12V，分为源输入和漏输入。源输入是指输入电压为0V，COM端接24V，漏输入是指输入电压为24V，COM端0V；二是交流输入，输入规格为AC220V；第三种输入是模拟量输入，规格为0-20MA电流信号、4-20MA电流信号。

plc输出有三种类型：第一种是继电器输出，继电器输出反应速度慢，输出电流大，一般达到2A，但触电寿命短，输出频率低，最大1HZ；二是晶体管输出，晶体管输出反应速度快，输出电流小，接触寿命长，输出频率高，可达到10KHZ；三是模拟输出，规格一般为0-20MA电流信号、4-20MA电流信号、0-5V电压信号、0-10V电压信号等。

Product description

plc switching output types are roughly divided into three types, relay output type, transistor output type and thyristor output type. R-relay; t-transistor

Relay output AC DC can be, the transistor common 5vdc and 24vdc output, thyristor is relatively rare, only special output models have.

Considering the type of output module selected, usually the relay output module has low price, wide voltage range (can be connected to the mains), large load capacity, small on-voltage drop, strong ability to withstand instantaneous voltage and overcurrent, but short life, long response time, slow action speed and so on.

Transistor output (can be divided into PNP, NPN type) has the advantage of fast on-off speed (pulse output, suitable for high frequency), generally about 0.2ms; Long life; The disadvantage is low working voltage (can not be connected to the mains); The load capacity is weak, about 300mA.

Thyristor output module is suitable for DC load, frequent switching, fast reaction speed, long life, low inductive power factor load, but the price is more expensive, the overload capacity is poor.

PLC has three input types. One is DC input, generally DC24V or DC12V, which is divided into source input and leakage input. The source input means that the input voltage is 0V and the COM terminal is 24V. The leakage input means that the input voltage is 24V and the COM terminal is 0V. The second is AC input, the input specification is AC220V; The third type of input is an analog input, and the specifications are 0-20MA current signal and 4-20MA current signal.

There are three types of plc output: the first is the relay output, the relay output response speed is slow, the output current is large, generally up to 2A, but the electric shock life is short, the output frequency is low, the maximum is 1HZ; The second is the transistor output, the transistor output reaction speed is fast, the output current is small, the contact life is long, the output frequency is high, can reach 10KHZ; The third is the analog output, the specifications are generally 0-20MA current signal, 4-20MA current signal, 0-5V voltage signal, 0-10V voltage signal, etc.
