Counting resolution down to 2.5 µs minimum pulse width, with signal thresholds defined: signal '1' at +11 to +28.8 V, signal '0' at -28.8 to +5 V. Power is drawn from the S7-300 backplane bus (5 V DC, 160 mA max) plus a separate 24 V DC supply (20.4–28.8 V, dynamic 18.5–30.2 V) for the inputs and outputs. Typical power loss is 4.5 W.","metaTitle":"Siemens 6ES7350-1AH02-0AE0 Counter Module, 200 kHz, eol_hot","metaDescription":"Siemens 6ES7350-1AH02-0AE0 SIMATIC S7-300 FM 350-1 counter module (EOL). 200 kHz counting, 32-bit, RS422.
