External wiring connection: 40 pin connector two.
1, the switch quantity acquisition and switch control and RS-485 bus are isolated from each other, and isolated from the whole system.
2, the power supply line has anti reverse connect function, once the wrong power line,
Will automatically cut off the power to protect the entire module is not damaged L26CPU-PBT MELSAP-L Manual L26CPU-PBT Programming Manual.
With over-voltage protection function, when the voltage is too high, automatic disconnection,
Protecting the entire module is not damaged.
3, RS-485 interface with 600W lightning protection and surge protection function, with 3000V photoelectric isolation.
4, the use of Modbus protocol, good general, can be very convenient and other systems,
Customers can also according to their own personal needs, custom related agreements, convenient and flexible L26CPU-PBT MELSAP-L Manual L26CPU-PBT Programming Manual.
5, communication lines using RS-485 bus, support for multiple modules in parallel use,
Easy to expand the system, good scalability. Number of input channels: 8ch.
Input current: DC0 ~ 20mA.
Conversion speed: 1ms/ch.
Resolution: 1/8000.
By shifting the function easily when the system starts to fine tune the movement function.
Shift the set value to (shift to) the function of the digital output value.
If you change the conversion value, the value is reflected in real time to the value of the scale (numeric value),
Can easily complete the fine-tuning of the system startup.
Extended detection method based on usage
Anomaly detection and extension of input signal
The detection method of the abnormal detection function of the input signal can be extended to detect the abnormal detection function of the input signal which iss outside the range of the set range L26CPU-PBT MELSAP-L Manual L26CPU-PBT Programming Manual.
For the detection of the lower limit or the upper limit of the input signal abnormality, or when the detection of the broken line is performed.
Enter rannge extension
Range of scalable input range L26CPU-PBT MELSAP-L Manual L26CPU-PBT Programming Manual.
Combined with the abnormal detection function of the input signal, the broken line can be easily detected.
