Siemens 6ES7350-1AH01-0AE0 SIMATIC S7 PLC Module

Siemens 6ES7350-1AH01-0AE0 FM 350-1 Counter Module for S7-300 and M7-300 provides a single high-speed counter channel for incremental encoders, supporting up to 500 kHz. The module offers 3 digital inputs, 2 digital outputs, and 1 counter input, all in a compact 40 x 125 x 120 mm enclosure weighing about 250 g that mounts on the standard S7-300 rack. It accepts 5 V and 24 V incremental encoders and supports isochronous counting for deterministic pulse timing as well as a measurement mode for rate and timing analysis. This counter module extends SIMATIC S7-300 and M7-300 systems with precise encoder pulse counting for applications such as motion control feedback on conveyors, rotational speed measurement, and process monitoring where a dedicated high-speed counter channel is required. The FM 350-1 is designed for integration into existing Siemens automation setups and leverages familiar FM 350-1 specifications for compatibility and reliability.
