Ready-to-Rack Summary

• Part Number: 6ES7332-5HB01-0AB0 (2-Channel Analog Output, 16-bit)
• Condition: Factory New Sealed in Original Siemens Packaging
• Warranty: 24 months (with full 16-bit linearity & load test certificate)
• Availability: 24-hour worldwide dispatch from EU/US stock
• Channels: 2 individually isolated outputs (0–10 V, ±10 V, 0–20 mA, 4–20 mA, 16-bit)

The Most Popular 2-Channel Analog Output Card for S7-300 in 2025

Still the first choice when you need precise, isolated control of valves, drives, positioners, or heaters with full 16-bit resolution and true galvanic isolation. Plants love it because:

• Direct replacement for older 5HD/5HF modules – same wiring, better performance
• 750 Ω load on current / 1000 pF on voltage – drives long cables without boosters
• Open-circuit detection on 4–20 mA + substitute value strategy
• Full HART pass-through support for smart positioners

Failure Symptoms Triggering Immediate Replacement

Instrument techs order this exact card when:

• “SM 332 channel fault” or output stuck at 0 mA / 0 V
• 4–20 mA loop shows exactly 22 mA (internal fault value)
• Valve positioner no longer responds to setpoint changes
• Diagnostic buffer “short-circuit to M” or “open circuit” on healthy wiring

Real-World Deployments 2024–2025

• Process Control: Flow & pressure control valves in refineries (Fisher, Samson, Masoneilan)
• Burner Management: Precise air/fuel ratio control via 4–20 mA positioners
• Test Stands: Variable frequency drive speed reference and damper actuators
