VOLTAGE INPUT PATH
A compact 1–5 V acquisition path for FIOAAV141 is a 16-channel analog input module for standardized 1–5 V DC signals. The inputs are non-isolated and differential. The module can be used in dual-redundant configuration and is designed for FIO architectures installed in ESB bus node units, optical ESB bus node units and FIO field control units. The S50 configuration selects the standard type, no explosion protection and basic configuration. /K4A00 adds the ATK4A-00 KS Cable Interface Adapter. |

| AAB141-S50/K4A00 | 1–5 V / 4–20 mA | Non-isolated | Mixed voltage/current input |
AAV141 is differentiated by its 1–5 V input range and non-isolated differential architecture. AAI141 targets 4–20 mA input, while AAV144 provides isolated voltage input and AAB141 accepts both voltage and current input types.

| Q1 · When should AAV141-S50/K4A00 be selected instead of AAI141-S50/K4A00? AAV141 is designed for 1–5 V DC input, while AAI141 is the 4–20 mA input variant. The field transmitter signal type should therefore be checked before replacement. |
Q2 · What does /K4A00 add to AAV141-S50/K4A00? /K4A00 specifies the KS Cable Interface Adapter, model ATK4A-00, for the module's external connection arrangement. |
| Q3 · Does AAV141-S50/K4A00 provide channel-to-channel isolation? No. AAV141 is specified as a 16-channel non-isolated module with differential voltage inputs. Applications requiring isolated voltage inputs should be evaluated against the isolated AAV144 family. |
Q4 · What input conditions should be checked before replacing an AAV141-S50/K4A00? Check that the field signal is 1–5 V DC, the common-mode voltage is within the specified ±1 V allowance, and the applied input remains within the ±7.5 V allowable input range. |
| Q5 · Can AAV141-S50/K4A00 be used in a redundant FIO arrangement? Yes. The AAV141 family can be used in dual-redundant configuration. The actual node, slot and system configuration should be matched to the existing FIO architecture. |
