Product description

The Siemens SIPLUS S7-300 SM 331 analog input module, part number 6AG1331-7TB00-7AB0, is based on the standard 6ES7331-7TB00-0AB0 module but features enhanced environmental protection with conformal coating. This module provides 2 analog inputs (2AI) with HART communication capabilities and is designed to operate reliably in extreme temperatures ranging from -25°C to +70°C.

This ruggedized analog input module is ideal for demanding industrial environments where standard modules may fail. It is used in process automation, chemical plants, offshore applications, and other harsh conditions requiring precise analog signal acquisition with HART capabilities for diagnostics and parameterization. It integrates seamlessly into the S7-300 PLC system.

Stanlo Automation, a veteran-owned surplus parts distributor, offers the Siemens SIPLUS S7-300 SM 331 module (6AG1331-7TB00-7AB0). Ensure robust and reliable analog signal acquisition in extreme environments by sourcing your SIPLUS components from Stanlo Automation.
