Feature

●DT-122 is a 2-channel upper / lower limit voltage comparator module. It can be used to monitor the measured voltage. When the measured voltage is within the upper and lower voltage limits, the relay will turn on to control the normal operation of other devices.
●Relay switch output
●Dual voltage independent detection
●The upper and lower limit voltage values can be adjusted independently

Description

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.

Please note:

1. Due to the different monitor and light effect, the actual colour of the item may differ slightly from the colour shown in the pictures. Thank you.

2. Please allow for a 1 - 2 cm margin of error due to manual measurement.
