The Analog to Digital & Comparator Module is a module used to convert the analog signal to digital signal. It is using LM339 as comparator to compare incoming voltage and the preset voltage. Thus, it is also called comparator module. After comparing the incoming voltage and preset voltage, it will give an output either active high or active low depending on the user’s setting. Analog to Digital & Comparator Module consists of 4 channels for the inputs and outputs. The on boards’ presets are used to set the compare voltage level.
- Operating Voltage : 5-12 VDC
- Output Signal : Selectable either Active High or Active Low Digital Signal
- Board Size : 45mm x 45mm
- Channels : 4 Inputs Channel, 4 Outputs Channel
