UAC389AE02是ABB公司生產(chǎn)的一款模塊式PLC控制器。
它使用方便，編程簡(jiǎn)單，采用簡(jiǎn)明的梯形圖、邏輯圖或語句表等編程語言，而無需計(jì)算機(jī)知識(shí)，因此系統(tǒng)開發(fā)周期短，現(xiàn)場(chǎng)調(diào)試容易。另外，可在線修改程序，改變控制方案而不拆動(dòng)硬件。UAC389AE02功能強(qiáng)，性能價(jià)格比高，一臺(tái)小型PLC內(nèi)有成百上千個(gè)可供用戶使用的編程元件，有很強(qiáng)的功能，可以實(shí)現(xiàn)非常復(fù)雜的控制功能。它與相同功能的繼電器系統(tǒng)相比，具有很高的性能價(jià)格比。
UAC389AE02 HIEE300888R0002 數(shù)字電源控制板 UAC389AE溫度探頭一般不可以直接接入常用模擬量模塊，需要接入專用溫度模塊，或者加變送器。一般壓力傳感器也不能直接接入模擬量模塊，一般是購買自帶變送器，或者使用壓力變送器。

UAC389AE02 HIEE300888R0002 數(shù)字電源控制板 UAC389AE那么當(dāng)傳感器和變送器結(jié)合使用的時(shí)候可以將非電物理量轉(zhuǎn)換成統(tǒng)一的標(biāo)準(zhǔn)電量。這就是傳感器和變送器的一個(gè)作用。

UAC389AE02 HIEE300888R0002 數(shù)字電源控制板 UAC389AE傳感器和變送器轉(zhuǎn)換出來的是一個(gè)標(biāo)準(zhǔn)電量，是電信號(hào)，我們的PLC是不能直接接收電信號(hào)的，那么就需要一個(gè)轉(zhuǎn)換，也就是AD轉(zhuǎn)換，將模擬量轉(zhuǎn)換成數(shù)字量。

在我們PLC這邊，AD轉(zhuǎn)換器其實(shí)就是一個(gè)模擬量的輸入模塊，而DA轉(zhuǎn)換器就是模擬量的輸出模塊。

而對(duì)于模擬量輸出，我們是做模擬量控制變頻器速度，從而控制電機(jī)速度；或者是模擬量控制伺服力矩和速度控制；又或者是模擬量控制比例閥的開度控制等。

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.
