The 6ES7350-1AH02-0AE0: The module integrates three digital inputs (for gate start, gate stop, and setting the counter) and two digital outputs with a maximum output current of 300 mA each, clocked short-circuit protection included. 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.

Frequently asked questions
What replaces the 6ES7350-1AH02-0AE0 officially?
Siemens does not list a direct official successor for this order code. A system migration to a newer counter module (e.g., from the S7-1200 or S7-1500 family) would require rewiring and software rework.
