DSAO120A 3BSE018293R1 ABB 模拟输出板

DSAO120A 3BSE018293R1 ABB 模拟输出板类型大致分为三种,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

DSAO120A 3BSE018293R1 ABB 模拟输出板交流直流都可以,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。

ABB发明、制造了众多产品和技术，其中包括套三相输电系统、世界上台自冷式变压器、高压直流输电技术和台电动工业机器人，并率先将它们投入商业应用。ABB拥有***的产品线，包括全系列电力变压器和配电变压器，高、中、低压开关柜产品，交流和直流输配电系统，电力自动化系统，各种测量设备和传感器，实时控制和优化系统，机器人软硬件和仿真系统，节能的电机和传动系统，电力质量、转换和同步系统，保护电力系统安全的熔断和开关设备。这些产品已***应用于工业、商业、电力和公共事业中。

There are three types of analog output boards of DSAO120A 3BSE018293R1 ABB, namely relay output type, transistor output type and SCR output type. R- relay; T- transistor

The analog output board of DSAO120A 3BSE018293R1 ABB can be AC and DC. Transistors usually have 5vdc and 24vdc outputs, while silicon controlled rectifier is rare, only with special output models.

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

The advantages of transistor output (PNP and NPN) are fast on-off speed (pulse output, suitable for high frequency), which is generally about 0．2ms; Long life; Disadvantages are low working voltage (unable to connect to the mains); The load capacity is weak, about 300mA.

SCR output module is suitable for DC load with frequent switching, fast response, long service life and low inductive power factor, but it is expensive and has poor overload capacity.

There are three input types of PLC. One is DC input, generally DC24V or DC12V, which is divided into source input and drain input. Source input means that the input voltage is 0V, COM terminal is 24V, and drain input means that the input voltage is 24V, and COM terminal is 0v; The second is AC input, the input specification is AC 220 V; The third input is analog input, with specifications of 0-20MA current signal and 4-20MA current signal.

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

ABB invented and manufactured many products and technologies, including three-phase transmission system, world-class self-cooled transformer, HVDC transmission technology and an electric industrial robot, and took the lead in putting them into commercial application. ABB has a * * * product line, including a full range of power transformers and distribution transformers, high, medium and low voltage switchgear products, AC and DC power transmission and distribution systems, power automation systems, various measuring equipment and sensors, real-time control and optimization systems, robot software and hardware and simulation systems, energy-saving motors and transmission systems, power quality, conversion and synchronization systems, and fuse and switch devices to protect the safety of power systems. These products have been used in industry, commerce, electricity and public utilities.
