DB A20 AnyWire master station.
Transmission distance: the longest 3km.
Data input and output: up to 1024 points.
Connect up to 128 units.
Enter 512 points, 512 points out of the output.
Support environmental protection, high speed, long distance transmission and special distribution system to support the special flat cable, universal VCTF cable, universal single wire cable and other cable LJ71E71-100-CM PDF LJ71E71-100-CM
Using original transmission mode, there is almost no branch limit,
Supports the automatic track and ring transmission,
Can also create suitable for small and medium sized factory wiring system.
Support remote I/O, analog quantity, temperature and humidity terminal, anti false operation terminal and other equipment LJ71E71-100-CM PDF.
Up to 128 units from the station module
Can connect up to 128 units from the station module, for up to 1024 points (input 512 points / output 512 points) of the I/O control.
In addition, the parameters can be set through the switch, easy to set the transmission distance of 50m/200m/1km/3km. Number of input channels: 4ch.
Input voltage: DC - 10 ~ 10V.
Input current: DC0 ~ 20mA.
Conversion speed: 20 s/ch LJ71E71-100-CM PDF.
Resolution: 1/20000.
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 funcction of the input signal which is outside the range of the set range LJ71E71-100-CM datasheet.
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 LJ71E71-100-CM datasheet.
Combined with the abnormal detection function of the input signal, the broken line can be easily detected.
