GE Fanuc Field Control IC670CHS002 Terminal Block Connector Base

Product Overview

The IC670CHS002 (IC670-CHS-002) is a high-density, box-style terminal block connector base designed for the GE Fanuc Field Control I/O system. This base serves as the critical physical and electrical interface between the field wiring and the I/O modules, providing a robust termination point for industrial sensors and actuators. Engineered for high-availability environments, the IC670CHS002 allows for "Permanent Wiring," which enables maintenance teams to replace I/O modules without disconnecting any field wires, significantly reducing Mean Time to Repair (MTTR). Its compact, rugged design is ideal for distributed I/O architectures in power generation, material handling, and large-scale manufacturing where reliable signal integrity is paramount.

Technical Configuration

The IC670CHS002 features a 36-terminal box-style connector, optimized for organized and secure wire management. It is designed to be mounted on a standard DIN rail or directly to a backpanel within an enclosure. The base includes an internal bus interface that links the I/O module to the Bus Interface Unit (BIU), facilitating seamless data exchange. This specific model supports a wide range of digital and analog Field Control modules, providing the mechanical support and electrical isolation necessary for stable operation in electrically noisy industrial environments.

Technical Specifications

Technical FAQs

What is the difference between the IC670CHS002 and the IC670CHS001?

The IC670CHS002 is a box-style terminal block, which provides a more enclosed and protected termination environment compared to the IC670CHS001 barrier-style base. The box style is often preferred for finer gauge wiring and high-density signal layouts.

Can I use this base with any Field Control I/O module?

The IC670CHS002 is compatible with the majority of Field Control digital and analog I/O modules. However, you must verify that the specific module’s pinout matches the 36-terminal configuration of this base and that the mechanical keying is properly aligned.

How does this base support system maintenance?

Because the field wiring is terminated at the base rather than the module, the I/O module can be unplugged and replaced while the wiring remains intact. This eliminates the risk of wiring errors during a module swap.

Engineering & Installation Guide

• Wiring Discipline: When terminating wires into the 36-terminal box, ensure that each wire is stripped to the correct length (approx. 8 mm) to avoid exposed conductors or poor contact. Use ferrules for stranded wire to prevent fraying and potential short circuits between adjacent terminals.

• Mechanical Keying: Each Field Control module and base set should be keyed to prevent the wrong module type from being inserted. Before snapping the I/O module into the IC670CHS002, check that the plastic keying tabs are set correctly to match the module’s function (e.g., Digital Input vs. Analog Output).

• Grounding for Analog Signals: If using this base for analog modules, ensure the cable shields are properly landed on the designated ground terminals. To prevent ground loops, terminate the shield at the base end only and keep the field-side shield floating.
