Product description
Siemens SM 331 Analog Input Module – AI 8 x 14 Bit High-Speed (6ES7331-7HF00-0AB0 / 6ES7331-7HF01-0AB0)
The SM 331 is a high-performance analog input module for SIMATIC S7-300 automation systems, designed for precision measurement and rapid data acquisition. With 8 inputs grouped into 4 channel groups, it supports both voltage and current measurement and provides flexible configuration options for demanding industrial applications.
Key Features:
- 8 high-speed analog inputs with 14-bit resolution
- Programmable per channel group for voltage (±1V, ±5V, ±10V, 1–5V) or current (±20mA, 0–20mA, 4–20mA) measurements
- Isochronous mode support for synchronized data acquisition
- Programmable diagnostics and diagnostic interrupts
- Programmable limit monitoring for 2 channels with hardware interrupt on threshold exceedance
- Fast conversion times: as low as 52 μs per channel, basic execution time 0.42 ms
- Electrical isolation between channels, CPU, and load voltage for reliable operation
The SM 331 AI 8 x 14 Bit High-Speed module delivers fast, accurate, and reliable analog data acquisition, making it ideal for process control, monitoring, and automation systems requiring high precision and diagnostics capability.
