Ready-to-Rack Summary
- Part Number: 6ES7350-1AH03-0AE0 (1-Channel High-Speed Counter, 500 kHz)
- Condition: Factory New Sealed in Original Siemens Packaging
- Warranty: 24 months (with full 500 kHz pulse & encoder test certificate)
- Availability: 24-hour worldwide dispatch from EU/US stock
- Channels: 1 × 500 kHz counter (A/B/N 24 V or 5 V differential, SSI, incremental, pulse+direction)
The Fastest Single-Channel Counter for S7-300 in 2025
Still the number-one choice when you need precise, high-speed counting of encoders, proximity sensors, flow meters, or dosing pumps directly in the PLC rack – no external counter required. Plants keep it in stock because:
- True 500 kHz input frequency (4× evaluation) for high-resolution encoders
- Integrated digital outputs (2 × 24 V / 0.5 A) for limit values & hysteresis
- Direct SSI absolute encoder support up to 32 bit
- Full STEP 7 V5.7 and TIA Portal 18 integration with ready-made function blocks
Failure Symptoms Triggering Immediate Replacement
Maintenance teams order this exact card when:
- “FM 350-1 fault LED red” or counter value freezes
- Diagnostic buffer “overflow” or “input frequency too high”
- High-speed encoder no longer counts above 200 kHz
- Digital outputs stop switching at comparison values
Real-World Deployments 2024–2025
- Filling Lines: Krones & KHS – high-speed bottle counting & dosing
- Conveyor Systems: SSI Schäfer & Dematic – length measurement with incremental encoder
- Test Benches: Automotive & aerospace – crankshaft & camshaft position
