Introduction
Many applications in industrial environments require converting force into measurable electrical signals. Strain gauges or load cells can usually accomplish this task. However, the question remains: How do we process the measurement data from these electrical signals?
The I-7016 series modules are designed not only to process data from weighing sensors or strain gauges but also to provide linear mapping functionality. By using user-defined mapping tables, the measured data can be directly converted into weight. This series supports full-bridge strain gauges and offers the following I/O features:
- Strain Gauge Input Channels: 1-ch or 2-ch. Configurable voltage or current input ranges.
- Excitation Voltage Output Channel: 1-ch. Output Range: 0 to +10 V, drive capacity up to 40 mA.
- Digital Input Channel: 1-ch. Configurable for general input or 50 Hz event counter.
- Digital Output Channels: 4-ch. Configurable for general output or high/low alarms.
Comparison of I-7016(D) and I-7016P(D)
| Model | I-7016(D) | I-7016P(D) | |
|---|---|---|---|
| Feature | 4-wire strain gauge | 6-wire strain gauge | |
| Wiring Structure | Two for power, two for signal, total 4 wires | Adds two sense wires to measure excitation voltage | |
| Voltage Compensation | Cannot compensate for voltage drops caused by cable resistance | Can detect and compensate for voltage drops, maintaining stable excitation voltage | |
| Measurement Distance | Suitable for short distances (<10 meters) | Suitable for long-distance measurements (>10 meters), less affected by cable losses | |
| Accuracy | Lower accuracy, more susceptible to cable resistance and environmental temperature | Higher accuracy, especially advantageous in long-distance or high-precision measurements | |
| Application Scenarios | General testing and cost-sensitive applications | High-precision measurements, industrial environments, long-distance use | |
