It reads 24 VDC inputs (signal \"1\" from +11 to +30 V, signal \"0\" from -30 to +5 V) and fires outputs with a monoflop time you set in 16 µs steps up to 64 µs. ## SSI encoder interface and signal timing The FM352-5 talks to SSI absolute encoders using a 25-bit message frame with clock (CK, notCK) and data (DATA, notDATA) differential pairs. Shielded cable runs up to 600 m; unshielded drops to 100 m. The update time through the PLC interface is 5 ms typical (2.6 ms in practice). Output switching is fast: 0-to-1 in 1 µs max (0.6 µs at 50 mA, 1.0 µs at 0.5 A), 1-to-0 in 1.5 µs max (1.7 µs at 50 mA, 1.5 µs at 0.5 A). The module fires a hardware interrupt on eight configurable events and logs diagnostic alarms for missing supply rails (1L, 2L, 3L), MMC errors, output overloads, encoder supply faults, differential wire breaks, parameterization errors, and SSI message frame overflows. ## Lifecycle: EOL hot — sourcing reality The 6ES7352-5AH00-0AE0 carries an EOL hot lifecycle status.","metaTitle":"Siemens 6ES7352-5AH00-0AE0 FM352-5, 24V, EOL Hot","metaDescription":"Siemens 6ES7352-5AH00-0AE0 SIMATIC FM352-5 high-speed Boolean processor. 24V input, 5V logic, requires MMC.
