Each channel supports 32-bit or ±31-bit counting, with dedicated gate start and gate stop functions per channel for precise motion control sequences. ## Power and signal conditioning at 24 VDC Operates on a 24 VDC rated supply, drawing a typical power loss of 10 W, and can deliver up to 2 A on the backplane bus at ambient temperatures up to 60 °C. Digital inputs accept signal '1' from 11 to 30.2 V with a typical current draw of 9 mA per channel, while signal '0' spans -3 to +5 V, compliant with DIN 19234 for 2-wire and NAMUR sensors. Input delay is 50 µs max for a 0-to-1 transition, with a maximum input frequency of 20 kHz, making it suitable for high-speed counting on conveyors or rotating machinery. ## Mechanical fit and wiring A single 40-pin front connector is required for field wiring; the module provides eight digital outputs rated at 200 mA each with short-circuit protection, plus eight digital inputs. Unshielded cable runs up to 100 m are supported; shielded runs extend to 600 m for NAMUR or encoder signals in noisy environments.","metaTitle":"Siemens 6ES7350-2AH00-0AE0 FM 350-2 Counter Module","metaDescription":"Siemens SIMATIC S7-300 FM 350-2 counter module, 8 channels at 20 kHz.
