Single-Channel High-Speed Counter – Up to 500 kHz:Supports maximum pulse input frequency of 500 kHz (differential 5V), ideal for high-speed encoder and sensor signal acquisition.
Multiple Counting Modes for Flexible Applications:Supports single-phase, dual-phase (2x/4x), and quadrature A/B phase encoding, enabling direction detection and improved resolution for position measurement.
Standalone Operation – Reduces CPU Load:As an intelligent module, the FM 350-2 performs counting, comparison, and alarm functions independently, minimizing CPU processing burden in S7-300 systems.
Integrated Hardware Comparator for Precise Positioning:Built-in hardware comparator can trigger a digital output automatically when the count reaches a preset value, enabling precise control of actuators or alarms with zero delay.
Reference Point Detection for Absolute Positioning:Supports zero-pulse (Z-signal) recognition, allowing homing and absolute position tracking, suitable for feeders, cut-to-length machines, and robotic arms.
