Siemens 6ES7350-1AH03-0AE0 is a SIMATIC S7-300 FM 350-1 Counter Module configured for one channel, designed to count pulses from incremental encoders in S7-300 automation setups. This spare-part module accepts 5 V and 24 V encoder signals and supports counting up to 500 kHz, operating in ISOCHRONOUS mode to maintain precise timing in high-speed applications; it also includes access to various measuring range types with a configuration package on CD. Suited for integration within the SIMATIC S7-300 ecosystem, it provides a compact, dedicated counting function for motion and feedback tasks in industrial controls.
