Product details

The 6ES7354-1AH01-0AE0: It reads incremental encoder feedback on 5 V difference signals (A, notA, B, notB) up to 1 MHz, and also supports SSI absolute encoders for position retention after power-off. 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.

Frequently asked questions

What are the 5V and 24V requirements on this module?

The module needs a 5V supply for the differential encoder interface (RS422) and a 24V DC rated supply for the I/O and logic circuits. Both must be present for operation.

What is the maximum encoder input frequency?

The incremental encoder input can accept signals up to 1 MHz. The SSI absolute encoder interface runs at a maximum clock frequency of 1.25 Mbit/s with a shielded cable length limited to 10 m at that speed.
