On the I/O side: four digital inputs and four digital outputs, isolated via optocoupler, with maximum output current 300 mA and switching capacity up to 30 VA. The module requires both a 5 V supply (for the encoder interface) and a 24 V DC rated supply for the I/O and logic; power loss is typically 8 W. ## Sourcing reality for this EOL part For procurement: this part can be quoted to order through independent redistribution. No official replacement part number has been published, so a BOM-line substitution would require a full control-system redesign.","metaTitle":"Siemens 6ES7354-1AH01-0AE0 FM 354 Positioning, RS422 1 MHz","metaDescription":"Siemens S7-300 FM 354 positioning module 6ES7354-1AH01-0AE0, end-of-life (EOL), sourced to order.
