Input Signal and Channel Configuration
The AAI143 provides 16 isolated analog input channels for 4-20 mA field signals. Each channel measures its input independently, while the isolation between the input side and system side has a rated withstand voltage of 1500 V AC for one minute.
In addition, the module supports channel-level selection of 2-wire or 4-wire transmitter connections through setting pins. This configuration allows maintenance personnel to match the input arrangement to the connected field transmitter.
Transmitter Power Supply
The module supplies power to connected transmitters, with an output current limit of 25 mA. The specified supply voltage is at least 19.0 V at a 20 mA load and no more than 25.5 V at 0 mA.
Therefore, the transmitter supply characteristics should be checked against the connected instrument's voltage and current requirements before installation.
Ordering Configuration
The AAI143 product family includes several suffix and option configurations:
| Code | Description |
|---|---|
| -S | Standard type |
| -H | With HART digital communication |
| 5 | Without explosion protection |
| E | With explosion protection |
| 0 | Basic type |
| 3 | ISA Standard G3 option and temperature option (-20 to 70 deg C) |
| /K4A00 | KS Cable Interface Adapter for AEA4D Terminal Board, model ATK4A-00 |
| /A4S00 | Pressure Clamp Terminal Block, model ATA4S-00 |
| /A4S10 | Pressure Clamp Terminal Block with surge absorber, model ATA4S-10 |
| /A4D00 | Dual Pressure Clamp Terminal Block, model ATA4D-00 |
| /A4D10 | Dual Pressure Clamp Terminal Block with surge absorber, model ATA4D-10 |
| /CCC01 | MIL Cable Connector Cover, model ACCC01 |
Configuration note: The supplied ordering information lists /K4A00 as the KS Cable Interface Adapter option. However, the specified model is AAI143-S50/K4S00. The /K4S00 suffix does not appear in the provided option-code list, so its exact interface configuration should be confirmed before ordering.
Frequently Asked Questions
Q: How many analog input channels does the AAI143 provide?
A: It provides 16 isolated input channels. Each channel accepts a 4-20 mA current signal.
Q: Can the AAI143 connect to both 2-wire and 4-wire transmitters?
A: Yes. The module supports both transmitter types, with the selection made independently for each channel using its setting pin.
Q: Does the AAI143 support HART communication?
A: HART communication is available on the HART-enabled -H configuration. The specified -S configuration is identified as the standard type, so HART availability should not be assumed for AAI143-S50/K4S00.
