Product Description
The Yokogawa AAI143-S00/K4A00 is a 16-channel isolated analog input module designed to receive 4-20 mA current signals from field transmitters and transfer measurement data to a control system. It supports channel-level selection for 2-wire or 4-wire transmitters and provides a 10 ms data update period. This configuration includes a KS Cable Interface Adapter, model ATK4A-00, for connecting an AEA4D terminal board.

Signal Processing and Transmitter Connection
The module receives analog current signals in the 4-20 mA range through 16 isolated input channels. The 10 ms data update period defines how frequently the module updates its input data. The stated accuracy is +/- 16 uA, while the ambient temperature drift specification indicates an additional accuracy consideration when operating temperatures change.
Each channel supports configuration for either a 2-wire or 4-wire transmitter using a setting pin. The module's transmitter supply specifications and 25 mA current limit should be considered when checking field transmitter requirements and loop wiring.
Ordering Configuration
The complete model number identifies the module and its specified interface configuration.
| Code or Item | Description |
|---|---|
| AAI143 | 4-20 mA, 16-channel isolated analog input module |
| S | Standard type |
| 00 | Basic type designation, based on the supplied suffix information |
| K4A00 | Specified KS Cable Interface Adapter option |
| ATK4A-00 | Adapter model identified in the supplied configuration data |
The source information also lists other AAI143 options, including pressure clamp terminal blocks, dual pressure clamp terminal blocks, surge absorber variants, and a connector cover for MIL cable connections. These options have different ordering codes and should not be assumed to be included with the AAI143-S00/K4A00.
Frequently Asked Questions
Q: How many input signals can the AAI143-S00/K4A00 handle?
A: It provides 16 isolated analog input channels for 4-20 mA current signals.
Q: Can this module connect to both 2-wire and 4-wire transmitters?
A: Yes. The supplied specifications identify channel-level selection for 2-wire or 4-wire transmitters using a setting pin. Confirm the field wiring and transmitter power requirements before installation.
Q: Which interface adapter is specified for the AAI143-S00/K4A00?
A: The supplied ordering information identifies the KS Cable Interface Adapter ATK4A-00. The exact terminal board designation should be confirmed before ordering to avoid a mismatch between the module, adapter, and field wiring assembly.
