Intelligent Weighing Digital Display Module, TTL MODBUS-RTU Display Controller for Digital Electronic Scale 24Bit ADC Signal Transmitter

1.Introduction:
The weighing acquisition module is a high-performance, multi-functional electronic weighing device, which adopts advanced weighing sensing technology, which can measure the weight of the product in real time and display it with a five-digit code tube, and has the upper and lower limit alarm function, which can achieve accurate weighing control and monitoring.

At the same time, the product also has TTL communication connection and MODBUS RTU communication protocol, which can quickly communicate with PLC, computer and other equipment to achieve the transmission and remote control of weighing data. In addition, it also supports Type-C power supply and key debugging functions, which improves the convenience and stability of use. The MAX input is 12mV, which is not a voltage gauge and cannot be connected directly to the MV signal, only to the weighing sensor.

2.Feature:
1>.High-precision weighing sensors for accurate weight measurement and numerical display.
2>.The five-digit sensor display is intuitive and clear, allowing for high-speed weighing and is suitable for efficient weighing processes.
3>.Limit the alarm function to achieve early warning and strict control, and improve quality.
4>.Support TTL communication and MODBUS RTU communication protocol to quickly implement data transmission and remote control.
5>.Type-C/5V power supply and button debugging function, easy to use, strong stability.
6>.Lightweight and portable, easy to install and move, saving space and cost.

3.General Parameters:
1>.Lock: Press the SEL settings below, and the display window will display the indicator LOCK, then 1230, and then change to 1231 before you can enter the following parameters.
2>.Dot:
2.1>.20kg sensor, can be set with 3 decimal points 20.000kg
2.2>.200kg sensor, can be set with 2 small points 200.00kg.
2.3>.2000kg sensor, can be set with 1 decimal point 2000.0kg.
3>.Lb:
3.1>.0: Do not do anything.
3.2>.1 ~ 40: The higher the set value, the better the filtering effect, but the slower the speed.
4>.Ad-H: Acquisition speed (0 low speed, 1 fast speed)
5>.CLr:The power-on zero-tare range (0~999.9), the parameter is greater than zero, and the meter is automatically cleared and tare within this range when the meter is powered on.
6>.Fd: Selectable graduation values(1, 2, 5, 10, 20, 50, 100, 200)
7>.ZEro: The zero tracking range (0~9999) automatically tracks the deviation near the zero point of the automatic tracking weighing, so that the gross weight display is maintained to the zero point. Note: Automatic clearing is ineffective in automatic mode.
8>.Z-t: Zero tracking time (10.0~600.0s)
9>.FSET: Correction factor, display value = display value * 1.0000

4.Alarm Parameters:
1>. LoCK: Press the SEL settings below, and the display window will display the indicator LOCK, then 1230, and then change to 1232 before you can enter the following parameters.
2>. AL:
2.1>.PVL: Both ALI and AL2 are lower limit alarms, the measured value is lower than the lower limit, and the relay is engaged.
2.2>.PVH: Both ALI and AL2 are upper limit alarms, the measured value is higher than the upper limit, and the relay is engaged.
2.3>.PVHL: PWL: AL1 is the upper limit and AL2 is the lower limit.
2.4>.OFF: Closes the reporting function.
3>.AL1: When the measured value exceeds (50.0), the relay will act, and when the measured value is lower than 45.0, AL1 will be disconnected.
4>.AH1: Upper Limit Alarm Return Difference.
5>.AL2: The AL2 upper limit alarm is set to a fixed value, when the measured value exceeds (150.0), the relay acts, and when the measured value is lower than 145.0, AL1 is disconnected.
6>.AH2: Upper Limit Alarm Return Difference.

5.Calibrate the Sensor:
1>.Press and hold the subtraction button, the sensor should not be weighted, press the set button once, and change the number value to 0. Then press the setting, and the zero point calibration is completed.
     1.1>.AD: The zero point AD code value, the sensor does not put the weight, wait for 2s, and then press the set key to save the point code.
    1.2>.PL: Enter the weight value corresponding to the zero-point code value, and the value is set as the value just now that the weight is not placed on the sensor.
    1.3>.-END: Displaying END indicates that the calibration is completed and automatically returns to the working state.

2>.Press and hold the plus button, press the weight on the sensor, press the set button once, change the number value to the weight of the release, and then press down to set it, and the full calibration is completed.
     2.1>.AD: When the AD code is fully collected, the weight should be placed on the sensor, and after 2 seconds, press the set button to save the full code (the range of the sensor is more than 20%).
    2.2>.PL: Enter the weight value corresponding to the full code value, and just put the weight on the sensor, this value is set to how much or less, and press the set key to save.
    2.3>.-END: Showing END indicates that the calibration is completed and automatically returns to the working state.
