Specification parameters

Power Input: Supports multiple types of power inputs, including 24-60 Vdc, 48-150 Vdc, 130-250 Vdc, or 100-250 Vac, 50/60Hz. During DC input, the fluctuation range of the power supply voltage is ± 20%; When communicating input, the fluctuation range is -20% to+10%, and the ripple does not exceed 12%. The power-off withstand time is 50ms.

Load capacity: Different load ports (such as P125, P126, P127) have different power bearing capacities, generally up to<3Wdc or<8Vaac, and the maximum load can reach<5Wdc or<12Vaac (depending on the port).

Delay and settings: It has multiple delay types, such as DT or IDMT (including various curves such as IEC-STI, IEC_SI, etc.). The tripping delay time is 0-150s, with an accuracy of up to 0.01s. The TMS (time multiplier setting) range is 0.025-1.5, with an accuracy of 0.025. The reset feature is also DT or IDMT, RTMS (reset time multiplier setting) 0.025-1.5, accuracy 0.025, Treset (return time) 0.00s-100s, accuracy 0.01s.

Monitoring function: It has the function of monitoring the fundamental frequency of zero sequence current and zero sequence voltage. The minimum operating zero sequence voltage varies under different conditions, with 1V when Uen is 57-130V and 3V when Uen is 220-480V. The high sensitivity current setting (Cortec code P12-C-xx) is ie>range 0.002Ien-1 Ien, accuracy 0.001Ien, etc. (different sensitivities correspond to different ranges and accuracies).

Other settings: Sensitivity angle (0 ° -359 °, accuracy 1 °) and trip zone (10 ° -170 °, accuracy 1 °) can be set. Through the human-machine interface, parameter settings, status monitoring, and other operations can be conveniently performed. For example, the voltage can be set according to actual needs in the configuration/general menu options, such as setting it to 2 VPN+VR.

Core functions

Accurate control of motor running time: The core function is to accurately control the running time of various motors, ensuring that the motors can operate strictly according to the pre-set time series under different working conditions. Accurate control can be achieved during the start-up, acceleration, stable operation, and deceleration stages of the motor.

Voltage and frequency regulation: With advanced power electronics technology and intelligent control algorithms, the output voltage and frequency can be accurately adjusted according to the operating requirements of the motor under different working conditions, ensuring efficient and stable operation of the motor.

Working principle

The MV7306P23 timing module control board uses a microprocessor as the core control unit, which converts and stabilizes the input power supply to provide stable working power for the entire control board. The sensors inside the control board collect real-time parameters related to the operation of the motor, such as current, voltage, speed, etc., and transmit these parameters to the microprocessor. The microprocessor analyzes and processes the collected parameters based on preset control algorithms and time programs, and outputs precise control signals to control the conduction and shutdown of power devices through driving circuits, thereby achieving accurate control of motor operating time, voltage, and frequency.

Key advantages

High precision control: With advanced technology and algorithms, high-precision control of motor running time can be achieved, with a tripping delay time accuracy of up to 0.01s, ensuring the accuracy of the production process and effectively improving product quality and production efficiency.

Wide power supply adaptability range: Supports multiple power input types and has strong adaptability to power supply voltage fluctuations. It can work stably in complex and changing industrial power supply environments, reducing the requirements for power supply systems and improving the universality and reliability of equipment.

Rich functional configuration: With multiple delay types, monitoring functions, and flexible parameter setting options, it can meet diverse control needs in different industrial scenarios and has strong adaptability and flexibility.

Precautions

Installation environment: It should be installed in a dry, well ventilated environment without strong electromagnetic interference to avoid environmental factors affecting the normal operation of the control board. It is recommended to control the working temperature range within the specified range of the product to prevent damage to electronic components caused by excessively high or low temperatures.

Power connection: It is necessary to strictly follow the specifications and parameters for power connection to ensure the stability and correctness of power input. Prevent incorrect operations such as high or low power supply voltage, reversed polarity, etc., to avoid damaging the control board.

Parameter setting: When setting parameters, it is necessary to make reasonable settings based on the actual application scenario and motor characteristics to avoid abnormal motor operation or control board failure caused by improper parameter settings. For unfamiliar parameters, refer to the product manual or consult professional technicians.
