YOKOGAWA • ANALOG I/O
AAI841-S50
8-Channel Analog I/O Module
4–20 mA signal architecture for compact analog I/O integration
The AAI841 is an analog I/O module providing eight channels of 4–20 mA input and eight channels of 4–20 mA output in a non-isolated configuration. Its channel structure is intended for process control applications where analog signal acquisition and analog output are handled within the same I/O module.

| 01 |
Can AAI841-S50 replace an AAI841 module in an existing I/O configuration?
A replacement should be checked against the complete existing configuration, including host system compatibility, terminal arrangement, channel assignment and the exact suffix code. Matching only the base model name is not sufficient for a controlled replacement decision.
|
| 02 |
Is AAI841-S50 suitable when both analog input and analog output are required?
Yes. The AAI841 family is structured as an 8-channel input / 8-channel output analog I/O module, with 4–20 mA input and 4–20 mA output. This combined architecture is useful where both signal directions are required within the same module.
|
| 03 |
What should be checked before ordering AAI841-S50 for a 4–20 mA loop?
Confirm whether the existing loop requires input or output operation, verify the channel assignment and wiring arrangement, and check the module's non-isolated architecture against the plant's signal design.
|
| 04 |
When is AAI841-S50 different from an isolated analog module?
AAI841 is a non-isolated analog I/O design. If the application requires electrical isolation between channels or between field circuits and the I/O electronics, an isolated module from the appropriate Yokogawa family should be evaluated instead.
|
| 05 |
What details should be included when requesting AAI841-S50 for replacement?
Provide the exact part number, quantity, existing system or module position, required delivery date and destination. If possible, include the current module suffix and terminal arrangement so the replacement can be checked against the application.
