Siemens 6ES7350-2AH00-0AE0 Counter Module SIMATIC S7-300

Siemens 6ES7350-2AH00-0AE0 is a SIMATIC S7-300 counter module (FM 350-2) that adds eight counting channels to a compatible S7-300 rack, enabling high-speed pulse counting and timing analysis directly in the PLC. It is designed for precision feedback in automation tasks, offering functions for counting, frequency measurement, speed measurement, and period duration measurement, with the added capability of dosing/proportioning control where timing and pulse counts govern material flow or batch operations. The module accepts 24 V incremental encoder inputs and supports a maximum counting frequency of up to 20 kHz, delivering real-time pulse counting alongside timing data that can be used for closed-loop speed control, conveyor monitoring, or process timing. Integrated into the SIMATIC FM 350-2 family, the 6ES7350-2AH00-0AE0 works with STEP 7 hardware configuration and the broader SIMATIC software environment to produce reliable, multi-channel counting results across industrial automation tasks. This counter module is typically deployed in applications that require simultaneous monitoring of multiple rotating elements or encoders, where precise pulse counting and timing measurements translate into accurate speed, frequency, and flow control within an S7-300-based control system.
