Product Description
The Yokogawa AAI141-H50/K4A00 is a 16-channel analog input module designed to acquire 4-20 mA DC signals from field transmitters. It features non-isolated input channels, HART digital communication, and channel-level configuration for 2-wire or 4-wire transmitters. Furthermore, its 10 ms data update period and 100 ms step response support continuous process signal acquisition.
Input and Signal Processing
The AAI141-H50/K4A00 accepts 4-20 mA DC signals across 16 non-isolated input channels. Its input accuracy is ±16 µA, while the 10 ms data update period determines how frequently the module refreshes input data. Meanwhile, the 100 ms step response time describes the time required for the input to respond to a signal change.
The module supports HART communication, allowing digital communication alongside the 4-20 mA analog signal. In addition, users can configure each channel for either a 2-wire or 4-wire transmitter through the corresponding setting pin.
Transmitter Power Supply
The module provides transmitter power with the following output conditions:
- At 20 mA output current, the transmitter supply voltage is at least 14.8 V.
- At 0 mA output current, the maximum supply voltage is 26.4 V.
- The output current limit is 27 mA.
Therefore, users should check the transmitter's voltage requirements and current consumption when selecting field devices for this module.

Ordering Configuration
The full model number identifies the module and its ordering configuration:
| Code | Description |
|---|---|
| AAI141 | 16-channel analog input module, 4-20 mA, non-isolated |
| -H | With digital communication (HART protocol) |
| -5 | With no explosion protection |
| 0 | Basic type |
| /K4A00 | With KS Cable Interface Adapter, model ATK4A-00 |
The -H suffix identifies the HART communication version. In addition, the -5 suffix indicates that this configuration has no explosion protection. The /K4A00 option specifies the KS cable interface adapter rather than a pressure clamp terminal block.
Frequently Asked Questions
Q: Does the AAI141-H50/K4A00 support HART communication?
A: Yes. The -H suffix identifies the digital communication version, which supports HART communication alongside the 4-20 mA analog input signal.
Q: Can this module connect to both 2-wire and 4-wire transmitters?
A: Yes. Users can select the 2-wire or 4-wire transmitter configuration independently for each channel through the setting pin.
Q: Are the 16 input channels isolated from each other?
A: No. The AAI141 provides 16 non-isolated input channels. This characteristic should be considered when checking field wiring and signal isolation requirements.
