UAC389AE02 数字电源控制板

UAC389AE02是ABB公司生产的一款模块式PLC控制器。
它使用方便，编程简单，采用简明的梯形图、逻辑图或语句表等编程语言，而无需计算机知识，因此系统开发周期短，现场调试容易。另外，可在线修改程序，改变控制方案而不拆动硬件。UAC389AE02功能强，性能价格比高，一台小型PLC内有成百上千个可供用户使用的编程元件，有很强的功能，可以实现非常复杂的控制功能。它与相同功能的继电器系统相比，具有很高的性能价格比。
UAC389AE02 HIEE300888R0002 数字电源控制板 UAC389AE温度探头一般不可以直接接入常用模拟量模块，需要接入专用温度模块，或者加变送器。一般压力传感器也不能直接接入模拟量模块，一般是购买自带变送器，或者使用压力变送器。

UAC389AE02 HIEE300888R0002 数字电源控制板 UAC389AE那么当传感器和变送器结合使用的时候可以将非电物理量转换成统一的标准电量。这就是传感器和变送器的一个作用。

UAC389AE02 HIEE300888R0002 数字电源控制板 UAC389AE传感器和变送器转换出来的是一个标准电量，是电信号，我们的PLC是不能直接接收电信号的，那么就需要一个转换，也就是AD转换，将模拟量转换成数字量。

在我们PLC这边，AD转换器其实就是一个模拟量的输入模块，而DA转换器就是模拟量的输出模块。

而对于模拟量输出，我们是做模拟量控制变频器速度，从而控制电机速度；或者是模拟量控制伺服力矩和速度控制；又或者是模拟量控制比例阀的开度控制等。

UAC389AE02 is a modular PLC controller produced by ABB.
It is easy to use, simple programming, using concise ladder diagram, logic diagram or statement table programming language, without computer knowledge, so the system development cycle is short, the field debugging is easy. In addition, the program can be modified online to change the control scheme without dismantling the hardware. UAC389AE02 has strong functions, high performance-price ratio, and a small PLC has hundreds of programming components available to users, which has strong functions and can achieve very complex control functions. Compared with the relay system with the same function, it has a high performance-price ratio.
UAC389AE02 HIEE300888R0002 digital power control board UAC389AE temperature probe generally can not be directly connected to the common analog module, need to access the dedicated temperature module, or add a transmitter. Generally, the pressure sensor can not be directly connected to the analog module, which is generally to buy its own transmitter, or use a pressure transmitter.

UAC389AE02 HIEE300888R0002 Digital power control board UAC389AE Then when the sensor and transmitter are used together, the non-electrical physical quantity can be converted into a unified standard electricity. That’s where sensors and transmitters come in.

UAC389AE02 HIEE300888R0002 digital power control board UAC389AE sensor and transmitter conversion is a standard electricity, is an electrical signal, our PLC is not able to directly receive electrical signals, then you need a conversion, that is, AD conversion, the analog quantity into digital quantity.

In our PLC side, the AD converter is actually an analog input module, and the DA converter is an analog output module.

For the analog output, we do the analog control frequency converter speed, so as to control the motor speed; Or analog control servo torque and speed control; Or it is the opening control of the analog proportional valve.
