Common Applications
Product Precautions
AAI141-S00 brings sixteen current loops into one FIO module position with a 10 ms update cycle and direct support for two-wire and four-wire transmitter circuits.
- Acquires sixteen 4 to 20 mA process signals.
- Updates the module data every 10 ms.
- Accepts both two-wire and four-wire transmitter arrangements.
- Uses a non-isolated channel architecture for the documented FIO application.
AAI141-S00 should be matched to the documented system position, companion hardware and retained project configuration before the channel or station is returned to control.
Important Notice: Preserve the complete AAI141-S00 identity and verify its documented electrical, network or signal response before release.
