Description
Reducing the size, component cost, and power loss of solutions is becoming increasingly important for industrial applications. The analog I/O module 07AC91 GJR5252300R0101 for programmable controller (PLC) is a good example to meet such requirements.
Industry 4.0 points to the trend of deep automation combined with intelligent communication. Therefore, in process engineering, industrial automation and equipment management, PLC needs to be equipped with more I/O ports. If space is limited and the controller cannot fit more base surfaces, then we must increase module density to support more I/O demand. Optimization of power supply design obviously contributes to achieving these objectives.
Let’s take a look at the power requirements of the analog I/O module 07AC91 GJR5252300R0101 power supply design. The analog I/O module 07AC91 GJR5252300R0101 usually uses a 4-20mA current loop or +/-10V signal transmission. We need a DAC/ADC to do the conversion, usually powering 5V. In order to protect the device and to ensure that the required performance can be achieved, the supply rail must be isolated to offset ground movement or noise.
Therefore, the analog I/O module 07AC91 GJR5252300R0101 requires a 5V rail and +/-12 to +/ -15V separation rail for voltage signal transmission or current loop perfusion/pulling, isolated from the 24-V rail for power supply. Figure 2 shows a common implementation plan.
Function description：
According to the application fields of modern power electronics, we divide the power supply as follows:
1 Computer high efficiency green power supply
The rapid development of computer technology leads human into the information society, and also promotes the rapid development of power technology. In the 1980s, switching power supply was adopted in computers, which was the first to complete computer power generation. Then switching power technology has been introduced into the field of electronic and electrical equipment.
The development of computer technology, put forward green computer and green power. Green computers generally refer to environmentally friendly personal computers and related products, Green power refers to the efficient and power-saving power source related to green computers. According to the “Energy Star” program of the United States Environmental Protection Agency on June 17, 1992, desktop personal computers or related peripheral devices meet the requirements of green computers if their power consumption is less than 30 watts during sleep. Improving power efficiency is the fundamental way to reduce power consumption. For a current 200-watt switching power supply with 75% efficiency, the power supply itself consumes 50 watts of energy.
