Taidacent H56 DC Voltage Monitoring Relay Over Under Voltage Protection Relay Upper and Lower Limit Detection Control Switch


Product Description


It is mainly composed of intelligent DC voltmeter and DC relay control module, which not only realizes accurate measurement of DC voltage, but also can be combined according to various modes such as upper and lower limits of set voltage, various delays, timing and timing cycles. Flexible control of various systems, widely used in battery charge and discharge control (inverter, UPS, backup power supply and various DC electric equipment), automotive battery control, electric vehicle power supply control, DC motor control, photovoltaic power supply system and Over-voltage and under-voltage protection etc. The product design is strictly in accordance with the relevant national standards and electrical safety rules, using three high-brightness LED digital tube display, card slot installation method, so that your products can be marketed faster.

The relay load contact has three contacts (a set of conversions): common point (COM), normally closed point (ON), normally open point (OFF), when the relay is not energized, the relay is released, and the common point and normally closed point are connected , When the relay coil is energized, the relay is closed, the common terminal and the normally open point will be connected

The relay contact is equivalent to a switch and can be used in the control circuit of AC and DC power systems. At this time, the relay must be connected in series in the circuit, and the circuit power supply cannot be short-circuited. The maximum load current of the contact is 10A (DC30V/AC250V). The maximum load current of the contact is 10A (DC30V/AC250V). If it is used in a DC control circuit greater than 30V, a relay of the corresponding voltage level needs to be added before it can be used!



The working voltage is DC 12V, 24V, 48 optional.
F1: Automatic charge and discharge and voltage hysteresis control
F2: voltage overrun action mode (overvoltage and undervoltage protection)
F3: Battery automatic discharge control
F4: Timing (delay) control
F5: manual control
The upper and lower limit alarm values ​​of all the above functions are adjustable, and the alarm delay time is adjustable (0-999 seconds, 0-999 minutes), the power saving mode can be turned on, the digital tube is automatically turned off, and the default parameters are restored.


Function description:
F1: Automatic charge and discharge and voltage hysteresis control:
Function description: The automatic charge and discharge management of the battery is realized by setting the upper and lower voltage limits (over and under voltage) and the delay action time; when the battery voltage is lower than the set lower limit value, the relay delay action (connect ON/OFF) until the battery voltage is higher than the upper limit, the relay will delay action again (OFF/ON).
Scope of application: This function belongs to voltage hysteresis relay control; it is mostly used for battery charge and discharge control (inverter, UPS, backup power supply and various DC electric equipment), automobile battery control, electric vehicle power supply control, DC motor control, photovoltaic Power supply system, etc.; for example: the upper voltage limit is 14.0V and the lower limit is 11.5V. When the power is lower than 11.5V, the relay is disconnected until the battery voltage is higher than 14.5V.

F2: Voltage over-limit action mode (overvoltage and undervoltage protection):
Function description: Realize the real-time monitoring and control of the voltage by setting the voltage upper and lower limits (over and under voltage) and the delay action time; when the measured voltage is lower than the set lower limit (under voltage) or higher than the setting When the upper limit (overvoltage), the relay delay action (on/off); when the measured voltage is higher than the set lower limit (undervoltage) or lower than the set upper limit (overvoltage), The relay does not operate (keep off/on).
Scope of application: This function mainly realizes voltage over-limit protection or control, and is mostly used for over-limit control of various DC power supplies and batteries, as well as single charge and single discharge of batteries; (F1 is one-way action of voltage upper and lower limits, and F2 is two-way action ), this mode can be used as overvoltage and undervoltage protection, for example: the upper voltage limit is 14.0V and the lower limit is 11.5V. When the upper or lower limit is exceeded, the relay is turned off, and the voltage is between 11.5-14.0V and the relay is connected.

F3: Battery automatic discharge control:
Function description: When any one of the following two conditions is met, the relay is activated and the discharge is terminated:
1. When the discharge voltage reaches the set value, the relay is disconnected, the discharge is terminated, and the discharge time is displayed;
2. When the discharge time reaches the set value, the relay is turned off, the discharge is terminated, and the discharge termination voltage is displayed.
Application range: This function is to test and control the battery discharge capacity, you can set the lower limit value of discharge voltage and discharge time value; for example: for a 12V battery, the lower limit voltage value is set to 11V, the discharge time is set to 60 minutes, At this time, the battery starts to discharge. When the lower limit voltage value comes first, the discharge ends, indicating the discharge time; when the discharge time comes first, the discharge ends, indicating the discharge end voltage.

F4: Timing (delay) cycle control:
Function description 1: The relay performs periodic cycle action according to the set on and off time, this function is not controlled by the monitoring voltage.
Application range 1: This function is mainly used for the relay power-on cycle on-off or off-on alternate control, the on and off time can be arbitrarily set within 999 minutes according to the requirements; mostly used for the need to cycle Timed on and off control system.
Function description 2: The relay performs timing action according to the set delay (off) time after power-on (disconnect), this function is not controlled by the monitoring voltage.
Application range 2: This function is mainly used for the relay to be turned on or off regularly at power-on. The on and off time can be set arbitrarily within 999 minutes according to the requirements; it is mostly used in the control system that requires timing on and off; if needed Set the power-on relay to be turned on, and then turn off regularly, you need to set SL in 3-S to 0; if you need to set the power-on relay to turn off, and then turn on regularly, you need to set SH in 3-S to 0.

F5: Manual control:
Function description: This function can control the relay manually.
Operation method: After selecting this mode, in the normal display interface, short press U/D (operation key) to control the relay on or off. Note: In this mode, if the display function is automatically turned off, the wake-up display needs to press the SET button 5 times in succession to restart and wake up.
