Product Description
Ready-to-Rack Summary
- Part Number: 6ES7336-4GE00-0AB0 (6-Channel High-Accuracy Fail-Safe Analog Input, 24-bit, SIL 3 / PL e)
- Condition: Factory New Sealed in Original Siemens Packaging
- Warranty: 24 months (with full 24-bit calibration & safety certification)
- Availability: 24-hour worldwide dispatch from EU/US certified stock
- Channels: 6 × 4–20 mA high-precision fail-safe inputs (24-bit resolution, ±0.1 % accuracy)
The Highest-Accuracy Safety Analog Input for S7-300 F in 2025
The only S7-300 F module delivering certified 24-bit measurement accuracy in safety-critical loops – mandatory for custody transfer, high-integrity pressure protection (HIPPS), and turbine control where both precision and SIL 3 are non-negotiable. Plants specify it because:
- True 24-bit resolution (0.001 % FS) with integrated linearization and temperature compensation
- Direct 1oo2 evaluation with certified discrepancy monitoring down to 0.1 %
- Full HART pass-through while maintaining SIL 3 / PL e integrity
- PROFIsafe diagnostics and certified high-precision function blocks
Failure Symptoms Triggering Immediate Replacement
Safety & instrumentation teams replace this exact card when:
- “SM 336 F precision fault” or PROFIsafe “measurement deviation >0.1 %”
- Safety program trips with “high-integrity discrepancy” or “internal ADC fault”
- One channel reading frozen at exactly 3.75 mA or 20.95 mA during proof-test
- HART diagnostic data no longer updates from safety transmitter
Real-World Deployments 2024–2025
- HIPPS Systems: Offshore platforms & LNG terminals – certified overpressure protection
- Custody Transfer: Pipeline metering stations – legal-for-trade flow & pressure loops
- Turbine Control: GE & Siemens Energy – high-precision vibration & temperature safety shutdown
