SIEMENS S7-300 FM 350-2 is the intelligent 8-channel counter module

FM 350-2 counter moduleFM 350-2 counter module

  • 8-channel intelligent counter module for universal counting and measuring
  • To directly connect 24 V incremental encoders, direction sensors, initiators or NAMUR encoders
  • Check function with preselectable set points (number depends on mode)
  • Integrated digital outputs to output the response when the setpoint is reached
  • Operating modes:
    • Continuous/single/periodic counting
    • Frequency/speed measurement
    • Cycle duration measurement
    • Dosing

Note:

Incremental encoder and pre-assembled connecting cables for counter and positioning function are offered under SIMODRIVE Sensor and Motion Connect 500.
