Parameters:
Product name: DT-122 2-bit voltage comparator module.
2>.Working voltage: DC 4.5V-28V
3>. Working Current: 80mA
4> .Output type: relay switch output (no voltage output!!!)
Working temperature: -25°C ~ 85°C.
Working humidity: 5% ~ 95%RH
Module size: 71*48*19mm
Function:
1>. Set the top/bottom limit voltage value for TP1 (TP2) by setting 4 potentiometers.
2>. There are four pads next to 4 potentiometers that allow the upper/lower limit voltage value to be tested.
Relay is switched on when the input voltage of TP1(TP2) is within the range of the upper/lower voltage limit. Otherwise, the relay will remain off.
4. Note: no mutual interference between 2 inputs and outputs. They work independently.
Application:
1>. Industrial control equipment.
Thermostat
3. Solar charging protection.
Battery charge and discharge protection.
Package contents:
1 x DT-122 2-bit voltage comparator module.
