Voltage Relay Module Upper Lower Limit Detection Control DC24V Voltage Detection Charging Discharge Test Relay Module

Feature: 1. VOLTAGE DETECTION DISPLAY RANGE: Wide testing range from 0 99.9V, with highly accurate starting from 0.1V. Easy to use DC24V power supply for safe operations. 2. INDUSTRIAL CIRCUIT GUARD: Designed with multiple protective circuits including charge guard, discharge guard, overvoltage guard, undervoltage guard, and fixed point pulse for stable and secure performance. 3. MULTIFUNCTIONAL DETECTION: 7 voltage monitoring functions including charge monitoring, discharge monitoring, outside range closing, inside range closing, fixed point monitoring, fixed point self locking monitoring, and fixed point pulse monitoring for various scenarios. 4. INTELLIGENT AUTOMATION: Key application logic of the DC24V voltage relay module functions as a voltage sentinel for low voltage DC systems, providing automatic guard or control in response to voltage abnormalities. 5. WIDE APPLICATION: Triggers relay actions rapidly by monitoring specific low voltage range abnormalities to achieve the goals of protecting equipment, ensuring operation, and preventing accidents . Widely used in power systems, industrial automation, home appliances, automotive, and security systems. Specification: Item Type: Voltage Detection Relay ModuleRelay Touch Spot Maximum Current: 12A (please leave some margin for use) Setting Description:F03 working mode, non set state: Long press SET to select F03 working mode, press+and keys to select the desired function, then long press SET to save and exit Please note to set the upper and lower voltage limits as needed before setting this parameterH 1 Charge monitoring: When the monitoring voltage is lower than the lower limit voltage, the relay closes, and when it is higher, it disconnected H 3 Discharge monitoring: When the monitoring voltage is higher than the upper limit voltage, the relay closes, and when it is lower, it disconnected H 2 Outside range closing: When the monitoring voltage is between the upper and lower limit voltages, the relay disconnected, and closes in other states H 4 Inside range closing: When the monitoring voltage is between the upper and lower limit voltages, the relay closes, and disconnected in other states H 5 Point monitoring: When the monitoring voltage is higher than the lower limit voltage, the relay closes, and when it is lower, it disconnected H 6 Point self lock monitoring: When the monitoring voltage is higher than the lower limit voltage, the relay closes, and continues to stay closed until manual intervention or power loss H 7 Point pulse monitoring: When the monitoring voltage is equal to the lower limit voltage (+ 0.1V), the relay outputs a pulse signal F04 Calibration mode: Long press SET key to enter non setting state, press + key to choose, default error is 0, can be adjusted as needed1. For example, if the actual input voltage is 12.5V and the module displays 12.4V,the error can be corrected to 0.1V, which means 12.4+0.1=12.5 2. For example, if the actual input voltage is 12.5V and the module displays 12.6V, the error can be corrected to 0.1V, which means 12.6 0.1=12.5. Package List: 1 x Relay Module Note:
