Each channel counts up to 20 kHz (incremental encoder mode: 10 kHz) with 32-bit or ±31-bit resolution, and the module generates a hardware interrupt on configurable count limits or gate events. Typical power draw is 10 W from the 24 V DC backplane bus; the module's eight digital outputs each sink 0.5 A with resistive loads at up to 500 Hz switching frequency.","metaTitle":"Siemens 6ES7350-2AH01-0AE0 FM 350-2, 8 NAMUR Inputs, EOL","metaDescription":"Siemens 6ES7350-2AH01-0AE0 FM 350-2 counter module with 8 NAMUR inputs at 20 kHz.
