SIEMENS SIPLUS S7-300 SM 326 – Safety Integrated Overview

OverviewSIPLUS S7-300 SM 326 - Safety Integrated

  • Digital inputs for the fail-safe SIPLUS S7 systems
  • For connecting:
    • Switches and 2-wire proximity switches
    • Sensors according to NAMUR and mechanical contacts, also for signals from hazardous areas
  • With integral safety functions for fail-safe operation
  • Can be used in fail-safe operation
    • Centrally: with S7-31xF-2 DP
    • Distributed in ET 200M: With SIMATIC IM 151-7 F-CPU, S7-31xF-2 DP, S7-416F-2 and S7-400F/FH
  • In standard operation can be used in the same way as S7-300 modules
Note:

SIPLUS extreme products are based on SIMATIC standard products. The contents listed here were taken from the respective standard products. SIPLUS extreme-specific information was added.

Fail-safe digital input modules are suitable for connecting

  • Switches and 2-wire proximity switches (BEROs)
  • Sensors according to NAMUR and mechanical contacts, also for signals from hazardous areas

The modules are implemented centrally with SIMATIC S7-31xF-2 DP and in the ET 200M distributed I/O station in combination with SIMATIC IM 151-7 F-CPU, S7-31xF-2 DP, S7-416F-2 and S7-400F/FH. They can also be used in non-safety-relevant standard mode and then respond like standard S7-300 modules.
