Configuració
Follow these steps for proper installation and wiring of the Load Cell Sensor Transmitter AmpMòdul lifier.
Esquema de cablejat
Figura 1: Diagrama de cablejat. This diagram illustrates the connections for the sensor terminal, power supply, and output signals. The left terminals are for sensor input (+S, -S, +E, GND), and the right terminals are for power (Power Positive, Power Negative) and output (0-5V, 0-10V, 4-20mA).
- Sensor Terminal: Define wiring according to the sensor's sequence. For example, if the sensor's red wire is excitation positive, connect it to the transmitter's excitation positive (E+).
- Font d'alimentació: Connect the positive terminal of the 12-24V DC power supply to "Power Positive" and the negative terminal to "Power Negative".
- Senyals de sortida: The 0-5V, 0-10V, and 4-20mA outputs share a common negative connection with the power supply negative.

Instruccions de funcionament
After successful wiring, the module is ready for operation. Ensure all connections are secure before applying power.
- Encès: Apply DC 12-24V power to the VIN and GND terminals. The power supply indicator LED should illuminate.
- Connexió del sensor: Connect your load cell or strain sensor to the +S, -S, +E, and GND terminals on the left side of the module according to the sensor's specifications and the wiring diagram.
- Selecció de sortida: The module provides simultaneous 0-5V, 0-10V, and 4-20mA outputs. Select the appropriate output for your receiving device (e.g., PLC, microcontroller, display).
- Calibration (if necessary): Depending on the specific load cell and application, calibration may be required to accurately map the sensor's output to the desired voltage/current range. Refer to your load cell's documentation for calibration procedures. The potentiometers on the module may be used for fine-tuning the output range, but precise calibration typically involves external equipment.
- Seguiment: Observe the output current strength indicator and the readings on your connected device to ensure proper operation.
