5 slots.
Requires 1 power modules.
Used to install the old section of the large A series PLC module.
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order Q03UDCPU PID Control Instructions Manual Q03UDCPU Programming Manual Q03UDCPU
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read Q03UDCPU PID Control Instructions Manual Q03UDCPU Programming Manual.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scan cycle is determined by the three Q03UDCPU PID Control Instructions Manual Q03UDCPU Programming Manual.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.8 channel.
Input: DC4~20mA.
Output (resolution): 0~6400; 0~3200.
Conversion speed: 10ms/ channel.
18 point terminal station.
Isolation between channels.
Power supply to a two wire transmitter.
The possibility of expanding control with intelligent function.
At the same time, the channel isolation analog module realizes high isolation voltage,
Further improve the accuracy of the benchmark.
Provide support for process control using a general purpose programmable controller.
Flow meter, pressure meter, other sensors can be directly connected to analog input,
Control valve can also be directly connected to analog output.
Hardware and installation costs have been greatly reduced due to the need for an exterrnal isolation amplifier Q03UDCPU PID Control Instructions Manual Q03UDCPU Programming Manual.
High insulation strength.
Can isolate electrical interference, such as current and noise, etc..
Standard analog input module.
Isolated analog input modulee Q03UDCPU PID Control Instructions Manual Q03UDCPU Programming Manual.
No external isolation amplifier required.
Without the use of inter channel isolation analog modules.
Using the inter channel isolation analog module.
