Expert Review

“Reliable 16-channel input module. The 10 ms update speed suits fast processes. Drift is low (±4 mV/10°C). Use it for precise 1-5 V signal acquisition.”

Manager’s Insight

“Great value for Yokogawa systems. The non-isolated design saves space but keep common mode voltage under ±1 V. Easy to wire with pressure clamps.”

Application Scenarios

• Process monitoring with 1-5 V transmitters
• Data acquisition in DCS systems
• Replacement for older AAV141 modules
• Integration with CENTUM VP and ProSafe-RS
