Applications

The AAM10 is suited for a wide range of industrial process monitoring applications within CENTUM-based DCS environments:

• Process Industries: Monitoring temperature, pressure, flow, and level in oil and gas, chemical, and petrochemical plants 

• Power Generation: Boiler and turbine instrumentation signal acquisition

• Water & Wastewater Treatment: Flow and level monitoring

• Pharmaceutical Manufacturing: Critical process parameter monitoring

• Food & Beverage: Temperature and pressure loop monitoring

Key Benefits

Important Notes

• System Requirement: The AAM10 requires system software revision R2.07 or later for full compatibility 

• Power Supply: The module is powered via the CENTUM Node Interface Unit (AND50, ANS50, AND20, ANS20) or Field Control Station (PFCS/PFCD) 

• Current Loop Behavior: When the AAM10 is powered off or in an abnormal condition, the current input loop is open 

• Signal Sharing Restriction: Do not share current signals with other receivers. For shared signal applications, attach a 250 Ω shunt resistor and use voltage mode 

• Barrier Compatibility: Can be combined with MTL barrier 728; in this case, wiring resistance must be ≤10 Ω, and the 2-wire transmitter minimum operating voltage must be ≤12 V DC 

• Signal Configuration: Input signal type and ranges are set via software; proper configuration before commissioning is required 

FAQ

Q1: What signal types does the AAM10 accept?

A: The AAM10 accepts both 4-20 mA DC current and 1-5 V DC voltage signals. The input type is configurable via software .

Q2: Can the AAM10 directly power 2-wire transmitters?

A: Yes. The module provides an integrated 25.0 to 25.5 V DC loop supply with a 60 mA current limit for powering 2-wire field transmitters .

Q3: What is the data update period of the AAM10?

A: The fixed data update period is 50 ms .

Q4: Is the AAM10 hot-swappable?

A: Yes, the module supports online module replacement (hot-swap) on compatible CENTUM I/O racks, provided the replacement module shares identical hardware revision and channel configuration settings .

Q5: What is the accuracy of the AAM10?

A: Accuracy is ±4 mV for voltage input and ±16 µA for current input. Temperature drift is ±8 mV and ±32 µA per 10°C change .

Q6: What is the difference between AAM10 and AAM10B?

A: The standard AAM10 is used for standard analog signals. The AAM10B variant typically includes support for the BRAIN protocol, enabling digital communication and diagnostics with intelligent Yokogawa field devices .

Q7: Is the AAM10 compatible with CENTUM VP?

A: The AAM10 is primarily designed for CENTUM CS 3000 and CENTUM CS 1000 systems. While some hardware may be backward compatible, verify specific I/O bus compatibility if attempting to use it in a CENTUM VP system .

Q8: What isolation does the AAM10 provide?

A: The module provides input-to-system galvanic isolation with a 1500 V AC withstand voltage rating for 1 minute, protecting the control system from field-side noise and potential faults
