Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 6ES7326-1BK00-0AB0 is a SIMATIC S7-300 SM 326 fail-safe digital input module with 24 DC 24 V inputs. It integrates into Siemens S7 F-systems using PROFIsafe communication for safety-rated control. The module monitors multiple safety inputs such as emergency stops or safety door sensors, enabling certified safety functions (e.g., SIL 3 / PLe). It serves in applications requiring functional safety and diagnostics within distributed automation environments.
Best Suited For
- Integration into S7-300 fail-safe (F-) systems with PROFIsafe
- Monitoring of up to 24 safety-rated digital inputs (e.g., e-stop, interlocks)
- Applications requiring safety certification to SIL 3 / PLe levels
- Replacement or spare in safety I/O racks
