SIMATIC S7-300
F digital / analog modules
SM 336 F analog input - Safety Integrated
■ Overview
• Analog inputs for the failsafe SIMATIC S7 systems
• For connection of analog sensors with voltage and current
signals
• With integrated safety func tions for failsafe operation
• Can be used in the ET 200M distributed I/O station with
SIMATIC S7-31xF-2 DP, S7-416F-2 and S7-400F/FH
• Suitable for use in standard operation in the same way as
S7-300 modules
