Expert Review

“Versatile analog I/O module. 8 inputs and 8 outputs in one unit saves rack space. Accuracy is solid (±16 µA input). The 40 ms output response is fast enough for most loops.”

Manager’s Insight

“Cost-effective solution for Yokogawa DCS. The 2-wire/4-wire pin setting is handy. Use it for mixed signal applications – input 1-5 V, output 4-20 mA.”

Application Scenarios

• Process control with transmitters and actuators
• Data acquisition and loop control
• Replacement for older AAB841 modules
• Integration with CENTUM VP and ProSafe-RS
