Transmitter Configuration and Signal Processing
The AAI143 accepts 4-20 mA analog current signals from field transmitters through 16 electrically isolated input channels. Each channel can be configured for either a 2-wire or 4-wire transmitter using its setting pin. This allows different transmitter wiring arrangements to be handled at the channel level.
Furthermore, the module provides a 10 ms data update period and an accuracy of +/-16 uA. The input resistance varies with the input current when power is on, while the specified power-off resistance is at least 500 kohm.
Connection and Ordering Configuration
The /K4A00 option identifies the KS Cable Interface Adapter, model ATK4A-00. It provides the connection interface for an AEA4D terminal board.
The complete order code is AAI143-S53/K4A00. The adapter configuration should be checked when selecting the corresponding terminal board and cable arrangement.
