It fits a standard S7-300 slot and communicates over the backplane bus — no separate fieldbus gateway needed. ## Encoder compatibility and signal handling The FM 350-1 accepts 5V and 24V incremental encoder inputs at rates up to 500 kHz. Single-channel design means one encoder per module. If the application requires multiple axes, stack additional FM 350-1 modules in adjacent S7-300 slots — each occupies one slot and draws its power from the backplane. ## Sourcing the original vs. migrating to the successor The successor 6ES7350-1AH03-0AE0 is the drop-in hardware replacement — same form factor, same slot, same encoder types. The key delta is software: the newer module supports isochronous mode for deterministic timestamping and includes a measurement mode, delivered with a configuration package on CD. Existing STEP 7 projects may need a hardware catalog update to recognize the new order code.","metaTitle":"Siemens 6ES7350-1AH01-0AE0 FM 350-1 Counter Module, 500 kHz","metaDescription":"Siemens FM 350-1 counter module for S7-300, 1 channel up to 500 kHz.
