Product description

6AG1331-7KB02-2AB0 Siemens SIPLUS S7-300 SM 331 2AI Analog Input Module

Compact and feather-light, the SIPLUS S7-300 SM 331 module (6AG1331-7KB02-2AB0) is a great choice. Using it in a SIMATIC S7-300 automation system is its sole purpose. It has analogue input that is quite accurate.

It features enhanced conformal coating, providing extra durability in harsh industrial conditions. This includes protection against humidity, dust, and chemical exposure.

It operates across a wide temperature range from –25 °C to +70 °C. This ensures consistent performance, even in challenging manufacturing and processing plants.

Key features and capabilities:

  • Input Channels: 2 isolated analog inputs
  • Resolution Options: Configurable at 9, 12, or 14 bits
  • Signal Compatibility:
    Voltage (U)
    Current (I)
    Thermocouples
    Resistors
  • Diagnostics & Alarms: Built-in monitoring functions for system reliability
  • Hot-Swappable: Supports removal and insertion with an active backplane bus
  • Interface: 1 × 20-pole connector

Reliability and protection

With its galvanic isolation, the module minimizes electrical interference, ensuring precise data capture and stable operation. In order to save downtime and increase system safety, the integrated diagnostics and alarm features offer early detection of anomalies.

Increased resistance to environmental stress is a result of the conformal coating. Because of this, the 6AG1331-7KB02-2AB0 is a great option for automation systems, energy distribution, and process control in rigorous industrial settings.

Integration and use cases

This module increases the capacity for analogue measurements while being fully compatible with older SIMATIC systems; it integrates smoothly into current S7-300 racks. Its hot-swap capability is perfect for facilities that require continuous operation. This includes chemical plants, utilities, and food processing lines, where shutdowns can be costly.

Obsolescence note

The S7-300 series, including the SM 331 modules, is gradually being made obsolete by Siemens. The 6AG1331-7KB02-2AB0 is still commonly utilised in current setups. Customers should consider preparing for future upgrades. This will help ensure ongoing compatibility and reliable long-term support.
