The IC670CHS001E is a high-performance communication interface module manufactured by GE Fanuc, now part of Emerson’s Machine Automation Solutions portfolio. This module serves as the critical link between a Genius® I/O bus and a VersaMax® PLC or DCS system. Its core function is to act as a Genius Bus Controller (GBC), allowing the versatile and cost-effective VersaMax platform to seamlessly integrate with and manage a wide array of Genius I/O blocks, sensors, and devices. The IC670CHS001E effectively bridges two powerful GE industrial ecosystems, enabling centralized control and data acquisition from a distributed network of I/O.
As a key component within the VersaMax system, the IC670CHS001E module slots directly into a VersaMax CPU or network interface unit baseplate. It handles all protocol conversion and data exchange responsibilities, transparently mapping Genius field data into the VersaMax controller’s memory for logic execution. This capability is invaluable for modernizations or expansions where leveraging existing installed bases of robust Genius I/O is a strategic requirement. The IC670CHS001E provides immense value by protecting investments in legacy Genius devices while upgrading the central control system to the advanced VersaMax platform, offering a perfect blend of backward compatibility and forward-looking control technology.

Main Features and Advantages
The IC670CHS001E offers significant advantages for system integration and design flexibility. Its primary feature is seamless protocol translation, which allows a VersaMax CPU to communicate with and control Genius I/O blocks as if they were native modules, simplifying programming and configuration in control logic. The module provides robust diagnostics through its comprehensive LED status indicators, offering at-a-glance health checks for both the module itself and the entire connected Genius bus, enabling rapid troubleshooting and minimizing downtime.
A key advantage is the ability to leverage the extensive and proven range of Genius I/O products, known for their reliability in harsh industrial environments. This allows engineers to design distributed control systems where I/O is placed close to field devices, reducing wiring costs and improving signal integrity, while the VersaMax controller provides centralized intelligence. The IC670CHS001E supports the full Genius bus specification, including the ability to read diagnostic information from smart Genius devices, providing a deep level of system insight. This integration capability makes the IC670CHS001E an economically smart and technically superior solution for system expansion and modernization projects.
Application Field
The IC670CHS001E is primarily deployed in industrial automation scenarios that require the integration of Genius distributed I/O with a VersaMax control system. This is common in manufacturing plant modernization projects where the core control hardware is being upgraded to a VersaMax PLC, but the existing network of field-proven Genius I/O blocks remains in place and is too extensive or costly to replace. Its application is widespread in industries such as automotive manufacturing, food and beverage processing, and water/wastewater treatment facilities.
In these settings, the IC670CHS001E module is used to connect the central VersaMax controller to distributed Genius blocks that handle a vast array of signals: digital inputs from limit switches, digital outputs to solenoid valves, analog inputs from temperature and pressure transmitters, and analog outputs to control variable frequency drives. It is particularly valuable in applications requiring distributed control across a large physical area, such as a conveyor system or a processing pipeline, where the long-distance communication capabilities and robustness of the Genius bus are essential. The IC670CHS001E effectively future-proofs an control architecture by enabling a smooth technology transition.
