Concentrates sixteen current loops in one RX3i I/O position.
Product Overview
IC694ALG223-GL is the GL revision of Emerson base catalog IC694ALG223, a high-density PACSystems RX3i current-input module with sixteen channels.
Emerson publishes 0–20 mA and 4–20 mA input support, 12-bit resolution and a 13 ms speed specification for the base catalog module.
The GL suffix is retained as the procurement and installed-hardware identity. Base-catalog specifications do not authorize replacement by a different suffix without revision review.

Uses user-supplied 24 VDC in addition to backplane power.
Keeps the GL revision visible throughout quotation and acceptance.
Applications
- Process current-loop acquisition in supported RX3i racks.
- High-density transmitter monitoring where channel scaling is controlled in the project.
- Revision-controlled replacement of an installed IC694ALG223-GL.
- Maintenance work that includes loop-power and terminal inspection.
Installation
- Record the GL label, terminal assembly, channel ranges, scaling, loop power and alarm logic.
- Isolate field and rack power under the approved process procedure.
- Transfer wiring channel by channel and restore the controlled hardware configuration.
- Inject known current at every used channel and verify raw counts, scaling, alarms and interlocks.

FAQ
What evidence should accompany an IC694ALG223-GL enquiry?
Send module and terminal labels, rack and CPU models, project version, range map, loop-power source and required quantity.
Can a different IC694ALG223 suffix replace IC694ALG223-GL automatically?
No automatic interchange should be assumed. Review Emerson revision information and validate the installed rack and project.
How should IC694ALG223-GL be bench-checked?
Use a traceable current source on every channel and compare counts, diagnostics and scaling with approved limits.
What field-power detail matters for IC694ALG223-GL?
Emerson specifies user-supplied 24 VDC current in addition to 5 VDC backplane demand, so loop-power architecture must be documented.
What proves IC694ALG223-GL is ready for process service?
Confirm the GL revision, clean diagnostics and channel-by-channel current, scaling, alarm and interlock results.
