Information About 6ES7331-7NF00-0AB0
The 6ES7331-7NF00-0AB0 is part of the SIMATIC S7-300 SM331 family, designed for precise analog data acquisition in modular PLC systems. Its eight optically isolated analog inputs accept a wide range of industry-standard signals such as ±10 V, ±5 V, 1–5 V, ±20 mA, and 0/4–20 mA, making it suitable for diverse instrumentation. The module features adjustable integration times—10, 16.67, 20, or 100 ms—allowing users to balance noise immunity and response speed. Typical applications include process monitoring, current-loop measurement, and interfacing with analog sensors in automated systems requiring stable, high-resolution data.
Key Features:
- Eight analog inputs: Supports voltage and current ranges for flexible signal acquisition.
- 16-bit resolution: Ensures accurate and detailed measurement of analog values.
- Optical isolation: Improves signal quality and protects modules from electrical disturbances.
- Multiple input ranges: Accepts ±10 V, ±5 V, 1–5 V, ±20 mA, 0/4–20 mA signals.
- Configurable integration time: Selectable 10, 16.67, 20, or 100 ms filtering.
- High measurement accuracy: Voltage, current, and resistance accuracy ratings suitable for industrial use.
- Compact S7-300 form factor: 125 × 40 × 117 mm for efficient cabinet installation.
- Reliable performance: Designed for stable analog processing in demanding automation environments.
The 6ES7331-7NF00-0AB0 delivers the reliability and precision required for high-accuracy analog signal acquisition in SIMATIC S7-300 control systems.
