Acquires sixteen industrial current signals in one RX3i I/O position.
Product Identification
IC694ALG223 is Emerson’s PACSystems RX3i high-density analog current input module with sixteen channels.
The manufacturer specifies 0–20 mA and 4–20 mA input types, 12-bit resolution and a 13 ms speed specification.
This base catalog page is deliberately separate from revision-specific pages such as IC694ALG223-GL; a suffix on an installed module must remain part of the enquiry.

Functions
Supports the two current ranges published for the base catalog module.
Combines backplane power with documented user 24 VDC demand.
Provides the diagnostics and flexibility of the RX3i rack-based I/O family.
Applications
- Process transmitters using 0–20 mA or 4–20 mA signals.
- High-density current-loop monitoring in supported RX3i systems.
- Machine and process control where channel scaling is maintained in the project.
- Spare planning that keeps any installed hardware suffix in the acceptance record.
Lifecycle
- Archive terminal assignments, channel ranges, scaling and loop-power drawings.
- Inspect the terminal assembly and user 24 VDC supply during maintenance.
- Do not confuse IC694ALG223 with voltage-input or lower-density modules.
- Complete channel-by-channel current injection after any module exchange.
About IndustryParts
https://www.industryparts.com/Base catalog data stays separate from revision identity
IndustryParts reviews IC694ALG223 with the complete installed label so a GL, BB, FC or other revision is never silently discarded.
- Full label requested
- Loop power reviewed
- Sixteen channels verified
FAQ
Q01What should accompany an IC694ALG223 enquiry?
Provide the complete installed label including any suffix, terminal assembly, rack and CPU, project version, channel map and loop-power source.
Q02Why must an installed suffix still be reported for IC694ALG223?
The base catalog defines the function, but a suffix can identify a hardware revision that belongs in the compatibility and acceptance review.
Q03How should IC694ALG223 be tested before process release?
Inject traceable current on every used channel and verify raw value, scaling, diagnostics, alarms and interlocks.
Q04What power information matters for IC694ALG223?
Document both the 5 VDC backplane demand and the user-supplied 24 VDC arrangement, including loop current requirements.
Q05What proves IC694ALG223 is ready for service?
Confirm exact identity, clean diagnostics, stable loop power and approved channel-by-channel measurement and alarm results.
