Function Module：
The user can select from the following five kinds of functions in one, you can set and save function parameters are automatically saved parameter set, power-down is not lost.
Function1: Voltage measurement: this function is selected, the relay will not operate, digital display of the current measurement voltage.
Function 2: Charge monitoring: When the measured voltage falls below a preset voltage V1 and V2 in the lower one, relay, voltage V1 and V2 higher than the higher of a relay off.
Function3: Discharge Monitoring: When the measured voltage is higher than the preset voltage V1 and V2 higher one, relay, T1 and T2 voltage is lower than the lower one, the relay off.
Function 4: pull the interval: When measuring the voltage between V1 and V2 between, relay, the relay off other cases.
Function 5: interval outer pull: When the measured voltage falls below a preset voltage V1 and V2 in a lower or higher than the preset measuring a voltage higher voltages V1 and V2, the relay is energized; otherwise relay disconnect.

Used this device along side a solid state relay to fix an odd intermittent switched ground on a vehicle EVAP valve connection to the ECU. This intermittent ground destroyed 2 valves before I relealized it was switching so quickly, heat would build and blow the switching mechanism in the valve. Once the ECU legitimately calls for the valve to operate, the connection is fine, just intermittent (as in a dozen on/offs a second) when it is supposed to be completely off/deactivated.This device allowed me to set a delay of a few milliseconds before the EVAP valve would open, therefore taking the rapid switching out of the EVAP valve. So far, this device and my evap valve have lasted several weeks without issue.Instructions for programming are severely lacking. However, go UToob and search for "DVB01". A couple of videos there will explain in clear detail how to program.Also, I opted to solder my connections to the bottom of the circuit board where the screw down terminals attach at the through-holes. The screw down terminals just would not reliably hold on to 18 awg stranded copper. Honestly, even if the screw down terminals held, I would recommend soldering in this fashion if using in a vehicle environment. Also, I used a waterproof diy project box and installed the unit in my engine compartment away from moving objects, heat and in a place that stays relatively dry even when exposed to the elements.Overall, this device spared me from having to drop several hundred dollars on a new ECU and consistently does what it is programmed to do.One word of caution, the DC input and the measured ine input share a common ground, so if the DC line you want to measure is dependent on a switched ground, you need an additional device, such a solid state relay, to feed the measured line input of the comparator a single DC+ conductor.

This device has a number of uses and an ability to program in all types of applications. Highly recommend to the DIY guy.

Used this for a starter cut out circuit on a old truck so it couldn’t be cranked while running. Seems to work great, would have given it a 5 Stars if the instructions were written by someone who spoke English.

The product is exactly as described and delivered on time.I am using it as an auxiliary charger for my 12 volt solar system. If there is not enough sun this will draw current from the grid so that the battery voltage doesn’t fall below 12.3v or whatever voltage I want to set it to.So far it is working perfectly.
