Siemens 6ES7331-7PF01-0AB0 SIMATIC S7-300 SM 331 F Analog Input Module
Siemens 6ES7331-7PF01-0AB0 SIMATIC S7-300 SM 331 F Analog Input Module
Manufacturer: Siemens
Product No.: 6ES7331-7PF01-0AB0
Condition:1000 em estoque
Product Type: SIMATIC S7-300 SM 331 F Analog Input Module
Product Origin: Germany
Payment: T/T, Western Union
Weight: 1000g
Shipping port: Xiamen
Warranty: 12 months
- Suporte 24/7
- Devoluções em 30 dias
- Envio Rápido
Ready-to-Rack Summary
- Part Number: 6ES7331-7PF01-0AB0 (8-Channel Fail-Safe Analog Input, 16-bit, SIL 3 / PL e)
- Condition: Factory New Sealed in Original Siemens Packaging
- Warranty: 24 months (with full safety certification & calibration protocol)
- Availability: 24-hour worldwide dispatch from EU/US certified stock
- Channels: 8 × 4–20 mA fail-safe inputs (single-channel or 1oo2 evaluation, 16-bit)
The Benchmark for Safety-Related Analog Signals on S7-300 F in 2025
The only analog input module that brings certified SIL 3 / PL e 4‒20 mA measurement directly into S7-315F/317F safety programs – no external safety transmitters required. Plants rely on it for:
- Direct connection of safety pressure, level, flow, and temperature transmitters
- Integrated wire-break and short-circuit detection with discrepancy analysis
- Full PROFIsafe diagnostics and certified function blocks in STEP 7 Safety Advanced
- Still fully supported in TIA Portal 18 Safety
Failure Symptoms Triggering Immediate Replacement
Safety engineers order this exact card when:
- “SM 331 F fault LED red” or PROFIsafe “channel fault 0–3.8 mA / >21 mA”
- Safety program forces STOP with “analog discrepancy time exceeded”
- Annual proof-test fails on one or more channels
- Transmitter reading stuck at exactly 0 mA or 22.8 mA
Real-World Deployments 2024–2025
- Burner Management: John Zink & Saacke BMS – safety flame-scanner current loops
- Chemical Dosing: BASF & Evonik – fail-safe pH and flow monitoring
- Emergency Shutdown: Offshore platforms – critical pressure & level ESD inputs
