How to tell the motherboard powered plc cpu modules
Now the cpu is usually powered by a 12V , the output voltage is based on the type of CPU and BIOS parameters are automatically set early with the jumper settings, this depends on the motherboard design. Voltage between 1-2v it. plc cpu modules notebook and some less than 1V. So: the input FET is 12V ( motherboard before 2005 are 5V, 3.3V power supply ) output and plc communication module incentive side FET switching signal because it is the state , is the uncertainty of the multimeter ! CPU power supply module , an inductor with two capacitors is basically between 15W to 30W, with power divided by the current know how much voltage . Normal computer maintenance is not so troublesome , plc cpu modules that burned on another part of the same size on the line, pay attention to the voltage value on it. Almost all of the programmable logic controller plc components is the capacitors on the motherboard burned up to the general power supply module is divided into : CPU power supply Northbridge , Southbridge power , graphics power , memory, power supply, sound card supply these parts , this is a good quality motherboard characteristics .
Generally these can be a lot of shrinking supply circuit . That is why the motherboard with some of your chips and some cheap main reason .
Feeding circuit all the way from the two capacitors, two inductors, a rectifier coil. General CPU power module you can count the plc industrial controller number of capacitors arranged neatly near the CPU to determine a few phase supply. Others also generally be so judged .

Some of the main exposition plc cpu modules modules
If there is an alarm relay on the meter, then set the alarm temperature on the instrument, the output relay is directly connected to the digital inputs plc and public clients. If there is no alarm relay on the input module plc meter (meter is no such general alarm relay), direct access to analog values plc to make their own alarm in the program. And direct access to the analog case plc, and because plc and instrumentation wiring different models differ, analog signal inputs can be 4-20mA, it can be 0 - (5) 10V, can also be thermal resistance and the like, the situation is more, the need for specific models can be. What is the installation of the module depends on the general programmable logical controllers input and output modules are not installed the driver, but the Mitsubishi motion CPU modules need to install the driver and set up. General PLC run the installer to write a good program it. Not add a module plus a driver, such as AD / DA module, just write in the program on it. Some PLC is not with AI (analog input) and AO (analog output) function, but usually there with an expansion slot, or expansion socket for programmable logic controller adding analog input and output functions, 32DI (32 个input module), 32DO (32 output ports module), if the PLC itself comes with input and output ports is not enough, you can add these modules to perform the functions specified pull.
