quick Procurement Facts
- Part Number: 6ES7338-4BC01-0AB0
- Description: 1-Channel 24 V Incremental Encoder / SSI Absolute Encoder Interface, 32-bit Counter, 5 µs Time Base
- Condition: Factory New Sealed in Original Siemens Packaging
- Warranty: 24 months (with full encoder test report)
- Dispatch: 24-hour global shipping from EU/US stock
- Features: 1 × 24 V incremental (A/B/Z, 500 kHz max), 1 × SSI absolute (up to 32-bit, 2 MHz clock), isochronous mode capable
Why 6ES7338-4BC01-0AB0 Remains the Precision Champion in 2025
- Ultra-fast 5 µs counter resolution – perfect for high-speed packaging, printing, and servo positioning
- Simultaneous incremental + SSI support – one module handles both encoder types
- Direct integration into distributed ET 200S racks – saves central rack space
- Still the #1 choice for cut-to-length, flying saw, and rotary knife applications worldwide
Typical Failure Symptoms Driving Immediate Orders
- Counter value drift or sudden jump on high-speed lines
- OB diagnostic: “Encoder signal loss channel 0” or “SSI frame error”
- Z-pulse not detected → positioning offset > 0.5 mm
- Machine crash after years of 24/7 encoder pulses
