Setup
Follow these steps for proper installation and wiring of the Load Cell Sensor Transmitter Amplifier Module.
Wiring Diagram
Figure 1: Wiring Diagram. 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+).
- Power Supply: Connect the positive terminal of the 12-24V DC power supply to "Power Positive" and the negative terminal to "Power Negative".
- Output Signals: The 0-5V, 0-10V, and 4-20mA outputs share a common negative connection with the power supply negative.
Interface Definition
Figure 2: Module Overview. This image shows the general layout of the module with its input and output terminals.
| Signal Type | Wiring Identification | Wiring Definition |
|---|---|---|
| Input Signal (Sensor) | +S | Signal Positive |
| -S | Signal Negative | |
| +E | Excitation Power Supply Positive | |
| GND | Excitation Power Supply Negative | |
| Output Signal & Power | VIN | Power Supply Positive |
| GND | Power Supply Negative | |
| OUT | 4-20mA Output | |
| 0-5V | 0-5V Output | |
| 0-10V | 0-10V Output |
Note: The output excitation power supply voltage of the module is 12V. The current and voltage outputs are relative to GND. On the front of the board, the left 4 terminals connect to the sensor, and the right 5 terminals are for output and power supply.
Operating Instructions
After successful wiring, the module is ready for operation. Ensure all connections are secure before applying power.
- Power On: Apply DC 12-24V power to the VIN and GND terminals. The power supply indicator LED should illuminate.
- Sensor Connection: 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.
- Output Selection: 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.
- Monitoring: Observe the output current strength indicator and the readings on your connected device to ensure proper operation.

Maintenance
The Load Cell Sensor Transmitter Amplifier Module is designed for reliable operation with minimal maintenance. Adhere to the following guidelines:
- Environmental Conditions: Operate the module within its specified temperature range (up to 80 °C) and in a dry environment to prevent moisture damage.
- Cleaning: If necessary, gently clean the module with a soft, dry cloth. Avoid using liquids or abrasive cleaners.
- Connection Checks: Periodically inspect all wiring connections to ensure they remain secure and free from corrosion.
- Power Supply: Ensure the power supply voltage remains within the DC 12-24V range to prevent damage.
Troubleshooting
If you encounter issues with the module, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power indicator light | No power supply, incorrect voltage, reverse polarity, or faulty connection. | Check power supply (DC 12-24V), ensure correct polarity, and verify all power connections. |
| No output signal or incorrect output | Incorrect sensor wiring, faulty sensor, incorrect output terminal selection, or module malfunction. | Verify sensor wiring according to the diagram. Test the sensor independently. Ensure the correct output terminal (0-5V, 0-10V, 4-20mA) is connected to your receiving device. |
| Unstable or noisy output | Power supply ripple, electromagnetic interference, or loose connections. | Ensure a stable and clean power supply. Check for nearby sources of electromagnetic interference. Secure all wiring connections. |
| Output does not match expected range | Module requires calibration or sensor is not properly calibrated. | Perform calibration as per sensor and application requirements. Adjust potentiometers on the module if necessary for fine-tuning. |
