Information

Overview Manuals Common Applications Product Precautions

IC697ALG440 extends the matched converter assembly with sixteen current-input channels while the base module performs A/D conversion and PLC data transfer.

Adds sixteen current-input points to the high-level analog subsystem.
Shares conversion and data handling with the IC697ALG230 base module.
Supports three current ranges selected through software configuration.
Provides open-wire fault behavior for 4 to 20 mA operation.

IC697ALG440 should remain matched to its documented rack position, field interface and controller configuration through replacement and commissioning.

Important Notice: Record the complete IC697ALG440 identity, terminal assignments and channel response before removal, then prove the restored function before release.

Before installing GE IC697ALG440, confirm the documented system, interfaces and controlled configuration.

Confirm IC697ALG440 and its assigned IC697ALG230 base module.

Place every affected current loop in the approved maintenance state.

Record range selection and scaling for all used channels.

Isolate field sources before removing terminal wiring.

Preserve shield, common and channel assignments exactly.

Check the expander cable and base-module connection for damage.

Inject controlled current points across each configured range.

Review PLC values and open-wire diagnostics before release.

Technical notes

Record the complete IC697ALG440 identity, terminal assignments and channel response before removal, then prove the restored function before release.
