Which station hardware must be paired with IC670ALG620?

Use IC670ALG620 with the documented Field Control terminal block, compatible BIU or MFP, and the installed supported pt, ni, nife or cu rtds.

Which IC670ALG620 identity should be checked before installation?

Confirm the full IC670ALG620 catalog marking and the catalog number value IC670ALG620 against the installed station record.

Can IC670ALG620 be replaced by a visually similar Field Control module?

No direct substitution should be assumed. Match IC670ALG620, its terminal assignment, data allocation, signal type, power arrangement, and the documented required biu revision value 2.0 or later before migration.

Information

Overview Manuals Common Applications Product Precautions

GE IC670ALG620 is ge fanuc four-channel rtd analog input module. It excites and measures four three-wire or four-wire RTDs and reports compensated temperature or resistance values.

Accepts four independent RTD inputs
Supports three-wire and four-wire compensation
Reports temperature or resistance in tenths
Repeats internal A/D calibration every minute

IC670ALG620 operates with Supported Pt, Ni, NiFe or Cu RTDs, Three- or four-conductor sensor wiring, Field Control BIU revision 2.0 or later, Configured alarm and fault-clear data.

Engineered applications include four-channel RTD temperature measurement field station, Remote I/O cabinet integration, Installed-base module renewal, Controlled commissioning and diagnostics.

Important Notice: Match RTD type, alpha, wiring method and engineering units on every channel; prove lead compensation and open-sensor diagnostics before use.

The first document presents model-specific technical data and system identity. The second provides a separate installation, wiring and commissioning workflow.

four-channel RTD temperature measurement field station

Performs the documented four-channel rtd temperature measurement function at a distributed Field Control station.

Remote I/O cabinet integration

Exchanges configured process data with the host through the installed bus interface.

Installed-base module renewal

Restores an exact catalog-number position while preserving terminal and data identity.

Controlled commissioning and diagnostics

Supports staged wiring, configuration, diagnostic and functional verification.

Read the applicable GE Fanuc Field Control instructions before work. Verify IC670ALG620, its terminal assignment and the installed station configuration.

Verify the complete IC670ALG620 catalog marking and assigned Field Control position before work.

Place the connected four-channel RTD temperature measurement process in its approved maintenance state before disturbing the station.

Isolate BIU and field power, then confirm a safe condition at the IC670ALG620 terminal block.

Label and record channel conductors, returns, shields and external supply wiring before disconnecting any conductor from IC670ALG620.

Use ESD controls and protect the module connector, terminal block keying and exposed electronics.

Restore only the documented channel range, scaling, alarms and default behavior; do not copy settings from an adjacent module.

Energize in a controlled sequence and review PWR, channel, module and network diagnostics.

Complete low, midpoint and high signal checks plus alarm and diagnostic verification and retain the final result before returning the process to service.

Technical notes

Match RTD type, alpha, wiring method and engineering units on every channel; prove lead compensation and open-sensor diagnostics before use.
