1. Voltage Limits Setting: Users can set the upper and lower voltage limits using the digital voltage comparator.
2. High Accuracy: Measuring range is DC 0‑100V, measuring accuracy is +/‑0.1V, high accuracy.
3. Automatic Power Saving: The digital voltage comparator adds automatic power saving function, which can be set by users.
4. Auto Save: All Settings can be automatically saved, and the Settings will not be lost in power failure.
5. Delay Suction Delay Disconnect Functions: Provides five functions for users to choose from, to meet more application requirements, new 0‑99.9sec delay suction and 0‑99.9sec delay disconnect functions.

Module Interface:
Module Voltage Input Terminal: There Are 4 Wire Interfaces, and All Interfaces Are Equipped with Terminal Blocks, Which Are Convenient for Users
DC+: Positive Pole of DC Power Supply
DC-: Negative Pole of DC Power Supply
V+: Measuring Voltage Positive Pole
V-: Measuring Voltage Negative Pole
Load Output Terminal of Relay: There Are 3 Wire Interfaces, and All Interfaces Are Provided with Terminal Blocks
NO: Normally Open Interface of Relay; The Relay is Suspended Before Suction, and is Short Circuited to Com After Closing
COM: Relay Common Interface
NC: Normally Closed Interface of Relay, Short Circuited with Com Before Relay Closing, Suspended After Closing

How to Use:
After the installation is complete, you can use it 
Function 1: 
Voltage measurement: Select this function, the relay will not act, digital tube display the current measurement voltage; 
Function 2: 
Charge monitoring: when the measured voltage is lower than the lower limit voltage, the relay will pull in, higher than the upper limit voltage, the relay will disconnect; 
Function 3: 
Discharge monitoring: when the measured voltage is higher than the upper limit voltage, the relay draws, lower than the lower limit voltage, the relay is disconnec
