Product Description

This module is used to measure and monitor current consumption by utilizing a external shunt resistor. If the current exceeds a preset value, the relay

on the module is activated. Uses include building automation and facility management systems where acquiring information on energy usage can lead

to increased efficiency. They can also detect equipment issues and help prevent damage by detecting over-current and/or short-circuit conditions.

Technical Parameters

Electrical Diagram

Note: On the PCBA, CK is the (NO) normally open terminal, COM is the open terminal, CB is the (NC) normally closed terminal.

Mounting Diagram

35mm DIN rail mounting: Mount the sensor module onto the DIN rail (dark black) as shown in the figure.

Board Mount

Mount the PCB to the enclosure with screws. Mounting hole diameter is 3mm.

Notes

1. The module can only be powered by 24VDC.

2. Make sure the shunt is connected in series with the negative pole of the detection loop in order to read the signal normally.

3. Pay attention to the direction when connecting the signal terminal. The negative end of the load is the signal positive, and the negative end of the

power supply has the signal ground.

4. VR1 is a potentiometer for adjusting the threshold. The threshold voltage can be measured at point A to determine the value.

5. Due to the detection error of the shunt itself and the temperature drift of the op amp, there may be errors in the detection process. The module

power supply circuit and the current circuit under test should preferably be independent of each other, so as to avoid damage to the device

caused by interference and wiring errors.
