Siemens 6ES7350-2AH00-0AE0 Digital Counter Module

Siemens 6ES7350-2AH00-0AE0 is an eight-channel high‑speed counter module (FM 350‑2) designed for the SIMATIC S7‑300 family, expanding the PLC with dedicated counting and timing capabilities. It accepts 24 V encoders for counting and supports up to 20 kHz input frequency per channel, enabling precise frequency measurement and real‑time speed monitoring. In addition to counting, the module provides period duration measurement and proportional dosing (proportioning) functionality, making it suitable for applications such as conveyor counting, metering, and motion sensing within automated systems. When installed on the S7‑300 backplane, the FM 350‑2 offers independent counter channels that can run concurrently to handle multiple encoders or pulse trains, supporting accurate control loops and synchronization tasks across production lines. The part is identified by 6ES7350-2AH00-0AE0 and is positioned as the FM 350‑2 counter module for high‑speed pulse counting in Siemens’ SIMATIC S7‑300 ecosystem.
