GE Fanuc IC670CHS002 Replacement for Field Control Series

Product Overview

GE Fanuc IC670CHS002 Replacement for Field Control Series: Seamless Migration & Upgrade

Upgrading or replacing a legacy GE Fanuc Field Control system is one of the most common modernization challenges in industrial automation today. The IC670CHS002 is a Field Control I/O Terminal Block designed for use within the IC670 Series distributed I/O architecture — a platform widely deployed across manufacturing, oil & gas, water treatment, and process industries throughout the 1990s and 2000s. As original equipment reaches end-of-life and spare parts become increasingly scarce, sourcing a verified replacement IC670CHS002 is critical to maintaining uptime and avoiding costly system redesigns.

At TOPNLMS, we stock the IC670CHS002 as a direct replacement component, fully tested and ready to ship from Xiamen. Whether you are performing a like-for-like swap on an existing Field Control node or executing a phased migration from a legacy GE Fanuc PLC architecture to a modern PAC or DCS platform, this terminal block is the correct starting point for your retrofit project.

Seamless Upgrade Solutions

A successful Field Control system migration rarely involves replacing a single component in isolation. In practice, the IC670CHS002 terminal block is one element within a broader distributed I/O node that includes the IC670MDL640 or IC670MDL740 discrete I/O modules mounted directly above it, as well as the IC670ALG620 analog input module for process signal acquisition. These modules share the same DIN rail mounting system and snap directly onto the IC670CHS002 terminal block, preserving existing field wiring during a module swap — a significant advantage when minimizing downtime is the primary objective.

Power to the Field Control node is supplied through the IC670PWR002 power supply module, which feeds the backplane bus and all connected I/O modules. When replacing the IC670CHS002 terminal block, it is good practice to inspect the power supply module simultaneously, particularly in installations that have been in continuous service for more than a decade. Similarly, the IC670GBI002 Genius Bus Interface module — which handles communication between the Field Control node and the host PLC or DCS — should be verified for firmware compatibility if the host controller has been upgraded.

For sites migrating from a GE Series 90-30 (IC693 series) rack-based architecture to the distributed Field Control topology, the transition typically involves re-terminating field wiring from the old IC693 terminal blocks to the new IC670CHS002 bases. In these projects, signal isolators and marshalling panels are often introduced to manage the wiring transition cleanly, especially where intrinsically safe (IS) barriers or high-density I/O consolidation is required. The IC670MDL930 relay output module and IC670ALG230 analog output module are frequently specified alongside the IC670CHS002 in such retrofit bills of materials.

For customers integrating Field Control nodes into a Profibus DP or DeviceNet network — common in hybrid automation environments — the IC670GBI001 bus interface module provides the necessary protocol gateway, and the IC670CHS002 terminal block remains fully compatible as the field-side wiring base in these configurations.

Retrofit Guidance FAQ

Q: Can I replace the IC670CHS002 without re-terminating field wiring?
A: Yes — the IC670CHS002 is designed for tool-free module removal. The terminal block remains in place on the DIN rail while the I/O module above it is swapped. Field wiring stays connected to the terminal block throughout the process, eliminating the need for re-termination and significantly reducing the risk of wiring errors during maintenance.

Q: Is the IC670CHS002 compatible with all IC670 series I/O modules?
A: The IC670CHS002 is compatible with the standard IC670 MDL and ALG series I/O modules that use the matching connector footprint. Always verify the specific I/O module part number against the GE Fanuc Field Control System User’s Manual to confirm terminal block compatibility before installation.

Q: What communication protocols does the Field Control system support?
A: The IC670 Field Control architecture communicates via the GE Genius Bus (a proprietary token-passing fieldbus) through the IC670GBI series bus interface modules. The IC670CHS002 terminal block itself is a passive component and does not participate in protocol communication — it provides the physical wiring interface between field devices and the active I/O modules.

Q: Will the IC670CHS002 fit in the same physical space as the unit being replaced?
A: Yes — the IC670CHS002 uses the standard 35mm DIN rail mounting system. Provided the existing DIN rail and cabinet layout are unchanged, the replacement unit will fit without modification to the control cabinet structure.

Q: How do I handle the programming side of a Field Control node replacement?
A: The IC670CHS002 is a passive terminal block with no embedded firmware or configuration data. No programming changes are required when replacing this component. I/O module replacements within the same series may require I/O configuration verification in the host PLC or DCS programming environment (e.g., GE Proficy Machine Edition), but the terminal block swap itself is transparent to the control program.

Warranty Assurance

Every IC670CHS002 unit shipped by TOPNLMS is covered by a 12-month warranty from the date of delivery. Prior to shipment, each unit undergoes functional inspection and continuity testing to verify connector integrity and terminal block condition. Units that do not meet our quality standards are not shipped.

In the event of a warranty claim, TOPNLMS provides direct replacement support. Our technical team will coordinate the return and replacement process to minimize disruption to your operations. We understand that unplanned downtime in industrial environments carries significant operational and financial consequences, and our after-sales response is structured accordingly.

For urgent replacement requirements — including same-day quotation, express shipping from Xiamen, and pre-shipment test reports — please contact our sales team directly. We maintain stock of IC670CHS002 and related Field Control components to support both planned maintenance schedules and emergency breakdown situations.

Procurement teams can request a formal quotation, packing list, and certificate of conformance for each shipment. We support standard B2B procurement documentation requirements including commercial invoices, packing declarations, and country-of-origin certificates.
