SIMATIC S7-300
F digital / analog modules
SM 326 F digital output - Safety Integrated
■ Overview
• Digital outputs for the fa ilsafe SIMATIC S7 systems
• For connection of solenoid va lves, DC contactors and signaling
lamps
• With integrated safety func tions for failsafe operation
• Can be used in failsafe mode
- Centrally: with S7-31xF-2 DP
- Distributed in ET 200M: with SIMATIC S7-31xF-2DP,
S7-416F-2 and S7-400F/FH
• Suitable for use in standard operation in the same way as
S7-300 modules
