Product description

6AG1331-7NF00-2AB0 SIPLUS S7-300 SM 331 – Analog Input Module

The SIPLUS S7-300 SM 331 (6AG1331-7NF00-2AB0) is an analogue input module. It is both adaptable and durable. This module is specifically designed for use with Siemens S7-300 automation systems.

It features a conformal coating that protects its internal components. This ensures consistent operation, even in harsh industrial settings.

Key technical specifications:

  • Module Type: Analog input module (AI), 40-pole
  • Channels: 8 isolated analog inputs

Input Signal Ranges:

  • ±5 V / ±10 V
  • 1–5 V
  • ±20 mA
  • 0/4–20 mA
  • Resolution: 16-bit precision (55 ms conversion time)
  • Electrical Isolation: Single-rooting (50 V common mode)
  • Operating Temperature Range: -25 °C to +70 °C
  • Protective Features: Conformal coating against humidity, dust, and harsh contaminants

Even in highly stressful and electrically noisy conditions, this SIPLUS module maintains a high level of accuracy and reliability. It has a resolution of 16 bits. Because of this, it is applicable to measuring, monitoring, and control jobs in a wide range of sectors, as it enables accurate signal collection.

Durability is enhanced by the conformal coating, and it is easy to integrate with various types of sensors and industrial processes thanks to its varied input support. Installation and wiring are made easier by the 40-pole configuration, which means less downtime during setup and maintenance.

Applications

  • Industrial process control and monitoring
  • Precise analog signal acquisition in manufacturing lines
  • Legacy automation systems still operating with the S7-300 series
  • Harsh or variable environments requiring additional module protection

Obsolescence of the S7-300 Series

Siemens has begun the phase-out of the S7-300 family. This includes the SM 331 analogue input modules, like the 6AG1331-7NF00-2AB0. These modules are still supported in older systems and are used often. To guarantee system lifespan and continuous compatibility, manufacturers should plan future upgrades.

Summary

Designed for precision and longevity, the SIPLUS S7-300 SM 331 (6AG1331-7NF00-2AB0) is an analogue input module with a high resolution. It has a conformal coating and is compatible with a wide range of signals. This guarantees dependable operation under harsh conditions, even when the S7-300 series is getting close to its end of life.

Typical Applications

  • Industrial process control and monitoring
  • Precise analog signal acquisition in manufacturing lines
  • Legacy automation systems still operating with the S7-300 series
  • Harsh or variable environments requiring additional module protection
