8 channels.
Thermocouple (B, R, S, K, E, J, T, N)
Shedding detection function.
Conversion speed: 640ms/8 channel.
Inter channel isolation.
40 pin connector.
Most suitable for process control of isolated analog modules.
Temperature data can be collected by connecting thermocouple / thermal resistance Q172CPUN PID Control Instructions Manual Q172CPUN Programming Manual .
Products can choose multi-channel (8 channel) input type and channel isolation type Q172CPUN
Customers can choose the most suitable model according to the intended use.
Auto backup key data
Save the program and parameter files automatically to the program memory (ROM Flash) without using the backup battery,
To prevent the loss of the program and the parameters due to forgetting to replace the battery.
In addition, the soft component data and other important data can be backed up to the standard ROM,
In order to avoid during the long holiday and other planned downtime,
The data is lost due to battery depletion Q172CPUN PID Control Instructions Manual Q172CPUN Programming Manual .
The next time the power is turned on, the backup data will be automatically restored.
Reduce system downtime recovery time.
With a simple operation, you can back up all the data in the CPU to the memory card Q172CPUN PID Control Instructions Manual Q172CPUN Programming Manual .
Through regular backup, can be the latest parameters, procedures, etc. to save the storage card.
In the event of a CPU failure, after the replacement of CPU, can be a simple operation,
Restore the system by using the data storage card in advance.
Therefore, it is not necessary to spend time to manage the backup data, but also can shorten the recovery time of the system shutdown. Board module installation location: QS series power module mounting slot.
Suitable substrate module: QS034B.
Input power: AC100~120V.
Security PLC (secure programmable system) refers to the self or external components or the implementation of the failure of the agency,
Can still respond to and promptly cut off the output of the programmable system.
Different from ordinary PLC, security PLC not only can provide the function of ordinary PLC,
Safe control function can be realized,
Meet the requirements of the ISO 13849-1 EN and IEC 61508 control system safety related component standards.
PLC security market mainstream has oilz (Pilz) PSS 3000, PSS 4000,
PSS 4000 in addition to the security process can also be processed outside the standard control procedures.
All the componentts in the security PLC adopt the redundancy structure,
Two processor processing for cross detection,
The processing results of each processor are stored in their respective memoryy,
Output is only when the processing result is in full agreement,
If any inconsistency occurs during the process, the system is immediately shut down Q172CPUN PID Control Instructions Manual Q172CPUN Programming Manual Q172CPUN PID Control Instructions Manual Q172CPUN Programming Manual .
