Yokogawa AMM12T Voltage Input Multiplexer Module Original

Frequently Asked Questions (FAQ)

What is the function of the AMM12T Voltage Input Multiplexer Module?
The AMM12T module is designed to multiplex multiple voltage input signals (up to 16 channels) and interface them with the control system, supporting signal ranges from -10 V to +10 V.

Is the AMM12T module isolated per input channel?
Yes, each of the 16 input channels in the AMM12T module is galvanically isolated to ensure accurate signal acquisition and noise immunity.

What is the replacement model for AMM12T in the upgraded N-IO RIO system?
The AAV144-SM□ module replaces the AMM12T in Yokogawa’s N-IO system upgrade, offering equivalent or enhanced functionality.

What type of analog signals can the AMM12T handle?
The AMM12T module is designed specifically for voltage input signals, typically in the range of -10 V to +10 V.

Can the AMM12T be directly mounted into the NIU (Node Interface Unit)?
No, the AMM12T must be installed into a compatible I/O nest which is then connected to the NIU for integration with the system.

What are the power requirements for the AMM12T module?
The module operates on a 24 V DC system power supply provided through the I/O nest. It does not require a separate power supply.

How often does the module update input signal data?
The typical data update period for each channel is approximately 100 milliseconds, ensuring timely input acquisition.

Is the AMM12T compatible with HART communication?
No, the AMM12T module does not support HART communication. For HART-enabled modules, other models in Yokogawa’s analog input series should be considered.
