Product Description
The Yokogawa AA1143-H00/K4A00 is a 16-channel isolated analog input module designed to receive 4-20 mA DC signals from field transmitters. It supports HART communication for smart instrument diagnostics and remote configuration. Furthermore, the module provides selectable 2-wire and 4-wire transmitter configurations, allowing each channel to match the connected field device.

Input Channels and Signal Processing
The AA1143-H00/K4A00 receives analog current signals from field transmitters through 16 individually isolated input channels. It uses the standard 4-20 mA DC signal range, while the 10 ms data update period supports regular acquisition of process measurements.
Furthermore, the specified input accuracy of +/-16 uA and temperature drift of +/-16 uA per 10 deg C define its measurement performance. These values help engineers assess signal accuracy when selecting the module for process monitoring and control.
Transmitter Wiring and HART Communication
Each channel supports selectable 2-wire or 4-wire transmitter configurations through a setting pin. Therefore, engineers can configure individual channels according to the wiring requirements of the connected instruments rather than applying one configuration to all 16 channels.
In addition, HART communication supports digital communication with compatible smart field instruments over the analog current loop. For example, this allows access to supported instrument diagnostics and remote configuration functions alongside the 4-20 mA process signal.
Frequently Asked Questions
Q: How many field transmitters can the AA1143-H00/K4A00 connect to?
A: The module provides 16 individually isolated input channels. Each channel accepts a 4-20 mA DC signal from a field transmitter.
Q: Does the AA1143-H00/K4A00 support both 2-wire and 4-wire transmitters?
A: Yes. Each channel supports selectable 2-wire or 4-wire configuration through its setting pin. Engineers should select the appropriate configuration for the connected transmitter.
Q: Does this module support HART communication?
A: Yes. The module supports HART communication for compatible smart field instruments, enabling digital diagnostics and remote device configuration.
