Description:
1>. The module is a window voltage comparator module, built in LM2903 industrial chip. This module with coupling drive port.
    It can be realized through the photoelectric coupling device port isolation of different voltage drive.
2>. This module realizes window voltage comparison and output result output. It is mainly used in the precise control range of analog range.
3>. The output level is high when the input signal is in the upper and lower limits. When the input signal is greater than the upper limit or lower than the lower limit, the output is low.

Parameter:
1>. Power supply voltage: 3-28V
2>. Output high and low level (output current is about 5MA)
3>. The output current coupling voltage is controlled as the decision.
The onboard optical coupler is 817, output with 100 ohm current limiting resistor (the resistor can be adjusted according to need).
4>. Board size: length 50mm, width 21mm, Center distance of locating hole: 35.5mm
