Product description
6AG1326-1RF01-4AB0 Siemens SIPLUS S7-300 SM 326F DI8 NAMUR Safety Digital Input Module
The Siemens 6AG1326-1RF01-4AB0 is a specialised digital input module. It is part of the SIPLUS S7-300 range and focusses on safety. This module is designed to provide fail-safe automation in challenging environments with high operational demands.
This unit follows the 6ES7326-1RF01-0AB0 standard. Its improved conformal coating technology makes it very resistant to things like temperature changes, dust, moisture, and corrosive gases.
This module is built with digital inputs that comply with NAMUR standards. It offers a reliable interface for processing signals from sensors. Particularly in industrial settings where there is a substantial risk of injury due to exposure to chemicals, liquids, or explosives, these sensors are put in place. Engineers can rest easy in mission-critical safety applications thanks to the SIPLUS upgrades, which keep the component running reliably even under medial load strains.
Key technical specifications:
- Module Type: SM 326F fail-safe digital input
- Inputs: 8 digital inputs, 24 V DC, NAMUR standard
- Design: Safety-integrated for use within SIMATIC S7 F-systems
- Certification: Up to Category 4 (EN 954-1), SIL3 (IEC 61508), PL e (EN ISO 13849-1)
- Protective Coating: SIPLUS conformal coating for extended durability
- Weight: 0.56 kg
- Mounting: Standard S7-300 rack installation
- Temperature Range: Reliable operation between –25 °C and +60 °C
Functional safety and reliability
The 6AG1326-1RF01-4AB0 is crucial for safety-integrated automation. It is compatible with NAMUR sensors, which are widely used in process sectors such as chemical processing, water treatment, pharmaceuticals, and oil and gas.
Signals from NAMUR devices can be understood by the system. Because of this capability, it can differentiate between regular functioning, errors, and potentially harmful breakdowns. This ensures the safety of the plant’s machinery and the people who operate it.
Use of this module is intended for fail-safe setups. The SIMATIC S7 F-systems are compatible with it. Because of this, essential safety features like safe shutdown and emergency stop reactions are made possible. Engineers can quickly identify wiring mistakes, sensor malfunctions, or other irregularities with the help of the diagnostic alert capabilities, which further improves system transparency.
By integrating safety compliance up to SIL3 and PL e, Siemens ensures that the module can be deployed in applications where the highest levels of functional safety are mandatory. This certification makes it suitable for mission-critical systems where downtime or system failure could result in significant risk.
Just like the rest of the SIPLUS series, this module can survive in the harshest of environments. The 6AG1326-1RF01-4AB0 is protected from condensation, aggressive gases, dust, and corrosive atmospheres by virtue of its conformal coating. This additional resilience extends the service life of the component, reducing maintenance and replacement costs in the long term.
Obsolescence and migration planning
The 6AG1326-1RF01-4AB0 is going to be obsolete on October 1, 2025, as part of the S7-300 and ET 200M product family’s upcoming phase-out. Customers are being strongly encouraged by Siemens to prepare for migration.
