1>.The LM2903 chip is a core hysteresis voltage comparator control module.

Based on the original hysteresis module, the power supply filter and one optocoupler isolation output port are added, which is more suitable for industrial control.

2>.The hysteresis comparator is mainly used for voltage comparison, especially in the case where the voltage is not stable, it can solve the false trigger and jitter phenomenon of the comparator at the zero boundary.

3>.For example:If your input signal is 2.45V,but the voltage jitter between 2.43-2.47V due to interference or power supply, if the benchmark voltage is adjusted to 2.45V, then the normal comparator flips fast,it will be ouy of control. If it is used with delay comparator,then the hysteresis range is about 0.03V, when it is bigger than 2.45V, it will move and be flipped back when it is lower than 2.42V(2.45-0.03V). The small jittering will be avoided in that period.

4>.This module is widely used in the processing and collection of industrial field signals. It is more suitable for the docking and signal conversion between various modules in industrial control.

Module Parameters:

1>.the power supply voltage: 5-24V

2>.the output high and low level (output current is about 3-5MA)

3>.The optocoupler isolated output port realizes the independent extraction of the secondary legs of the optocoupler with a 100 ohm current limiting resistor.

Note:

Threshold voltage valid range 0 - (supply voltage minus 1V). For example, 5V power supply, the reference threshold voltage effective value is 0-4V, can achieve comparison output. If the threshold voltage is greater than 4V with a 5V supply, then the output will remain low for no output.
