| Manufacturer | GE / Emerson automation platform |
| Complete model | IC693ALG223-FA |
| Family | Series 90-30 / PACSystems RX3i |
| Hardware role | 16-channel current input module |
| The IC693ALG223-FA is a 16-channel single-ended current input module in the IC693ALG223 family. It accepts three selectable current ranges and provides channel scaling plus configurable high and low alarm limits. Enhanced 4–20 mA operation extends the measurable region below 4 mA to support open-loop detection. Each field loop is converted into a digital input value for the controller. All sixteen channels are refreshed in 13 ms. The module supports 0–20 mA, conventional 4–20 mA and Enhanced 4–20 mA operation, allowing one hardware type to serve mixed process measurements after correct configuration. |
Selection rule Match function, complete catalog code, carrier or rack position, wiring, revision and controller compatibility. |
| Channels | 16 single-ended current inputs |
| Selectable ranges | 0–20 mA, 4–20 mA or 4–20 mA Enhanced |
| Update time | 13 ms for all 16 channels |
| Input impedance | 250 ohms |
| Isolation | 1500 V field side to logic side |
| External power | 20 to 30 V DC; 65 mA plus loop current |

| RX3i universal backplane | Supported installation context | Use an eligible I/O slot |
| 01 | Remove rack and field power before inserting or extracting the module or terminal assembly. |
| 02 | Use a clean 20–30 V DC supply and observe common-return and shield-routing practices. |
| 03 | Configure each channel range before commissioning; a range mismatch changes scaling and diagnostics. |
| 04 | After replacement, inject known loop currents and verify engineering scaling, alarms and open-loop behavior. |

|
01
|
Can IC693ALG223-FA accept both 0–20 mA and 4–20 mA loops?
Yes. Each active channel is configured for 0–20 mA, 4–20 mA or Enhanced 4–20 mA operation.
|
|
02
|
What does Enhanced 4–20 mA add on IC693ALG223-FA?
It extends usable measurement below 4 mA, allowing the controller to distinguish low signal and open-loop conditions more effectively.
|
|
03
|
Is IC693ALG223-FA isolated channel-to-channel?
The published isolation is between the field side and logic side; the sixteen inputs are single-ended and share the field-side arrangement.
|
|
04
|
How should IC693ALG223-FA be tested after replacement?
Apply known currents near the low, mid and high points, then verify scaling, alarm thresholds and open-loop response.
|
|
05
|
What must be checked before buying IC693ALG223-FA?
Confirm the full revision code, controller family, eligible slot, terminal assembly, field supply and configured channel ranges.
