The 6ES7352-5AH11-0AE0: The 25-bit frame supports up to 2^25 positions per turn – fine enough for most multiturn applications. Update time from the PLC interface is 1.7 ms, which matters if you're chasing fast position changes. The monoflop time is settable in four steps: 16, 32, 48, or 64 µs – match it to your encoder's baud rate to avoid missed edges. Diagnostic alarms catch MMC errors, output overload, encoder supply overload, and differential wire breaks. Shielded cable max 600 m, unshielded 100 m. Temperature range covers -40 to 70 °C, so it'll live in a cold warehouse or a hot cabinet without derating. Power dissipation is 6.5 W typ – plan for that if the panel's tight on airflow.
