When using MR-J2CN1 connectors.
RS-422 communication cable is provided by the customer. Output points: 64 points.
Voltage: DC12/24V.
OFF leakage current: 0.1mA.
Output type: transistor output (type sink).
Response time: 2ms.
32 points / a common end.
40 pin connector.
With the surge absorber.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process FR-F720P-18.5K 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.
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.
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.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC.
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 channels.
Input: AC0~5A AC0~50A, CT, AC0~100 until AC0~600A.
Output: 0~10000.
18 point terminal.
Directly connected to the CT sensor, saving wiring and space of the CT input module.
Directly connected with CT sensor and programmable controller,
No need for external connection signal converter, etc..
Very accurate measurement results can be obtained by stable data transfer speed,
Then, load control and operation of the system and equipment are carried out, and the power supply system is managed and monitored.
Directly connect the CT sensor, saving wiring and space
In the case of no external signal converter, directly connected to the CT sensor.
A module can be used to measure up to 8 channels of alternating current, thereby reducing wiring time and cost.
Set the CT sensor type (input range) for each channel.
Through a module to select from AC0 ~ 5A to 600A ~ CT AC0 sensor.
Preventive maintenance can be carried out by detecting the peak current.
Peak current detection function
By detecting the peak current, the equipment can perform maintenance and troubleshooting.
Take the motor as an example, the load applied on the motor changes due to wear and damage of the gear,
Load current will suddenly change.
By detecting the transient peak current at this time, the fault of the equipment can be diagnosed.
Input signal error detection function
Can detect whether the CT input value is out of range (higher than the peak value).
Because the large current flow on the measurement object is beyond the range limit,
Therefore, the error of the measurement object can be monitored.
