Product Overview

The GE IC670CHS101 is a compact,DIN-rail mountable baseplate module that forms the mechanical and electrical backbone of the GE Series 90 Micro programmable logic controller(PLC)system.Designed for cost-sensitive,space-constrained applications,this carrier accommodates one CPU module—typically the IC670CPU101—and supports the direct attachment of up to four additional I/O or specialty modules on its right-hand side,enabling a fully integrated control solution in a footprint under 150 mm wide.Unlike modular rack-based systems,the GE IC670CHS101 integrates the backplane bus directly into the base,eliminating external cabling and reducing points of failure.

Positioned as an entry-level yet industrial-grade platform,the GE IC670CHS101 targets standalone machine control where reliability,ease of maintenance,and rapid deployment are paramount.It is commonly found in original equipment manufacturer(OEM)machinery,auxiliary plant systems,and small process skids that do not require high-speed motion or complex networking but demand robust performance in electrically noisy environments.The baseplate features gold-plated edge connectors and a secure snap-in retention mechanism to ensure stable module seating despite vibration or thermal cycling.Though part of GE’s legacy automation portfolio—now under Emerson—the GE IC670CHS101 remains widely supported due to its extensive installed base across water treatment,material handling,and building automation sectors.

Main Features and Advantages

Space-efficient design:The IC670CHS101 enables a complete micro-PLC system—including CPU,power interface,and I/O—in a remarkably compact form factor.This makes it ideal for retrofitting into existing panels or integrating into new OEM equipment where cabinet real estate is limited,such as conveyor junction boxes,pump control panels,or small HVAC units.

Tool-free module replacement:Field technicians can swap CPUs or I/O modules in seconds without tools—simply release the spring latch,remove the faulty unit,and insert the replacement.This modularity drastically reduces mean time to repair(MTTR),minimizing production downtime.The IC670CHS101’s precise alignment guides ensure consistent electrical contact,preventing intermittent communication faults caused by misseating.

Robust construction for industrial durability:Built with high-impact thermoplastic and reinforced guide rails,the IC670CHS101 withstands continuous mechanical stress from nearby motors,compressors,or transport vibrations.Its internal backplane eliminates wiring errors between modules,enhancing system reliability while simplifying initial commissioning and future upgrades.

Seamless compatibility within the Series 90 Micro ecosystem allows engineers to mix digital input/output,analog,and specialty modules(e.g.,RTD or communication adapters)on a single base.This flexibility supports evolving application needs without requiring a full system redesign.For facilities maintaining legacy GE infrastructure or deploying simple new controls,the IC670CHS101 offers a proven,economical foundation.

Application Field

The IC670CHS101 is predominantly used in decentralized control scenarios where a full-scale PLC system would be excessive.In municipal water pumping stations,a system built around the IC670CHS101 might monitor dry-run conditions,control lead-lag pump sequencing,and trigger alarm outputs based on level switches and pressure transducers—all within a NEMA 4X enclosure.Similarly,in packaging lines,it manages fill-level detection,capping motor activation,and reject gate operation using photoelectric sensors and discrete outputs.

In commercial building automation,the IC670CHS101 controls exhaust fans,chiller interlocks,and boiler staging based on temperature and occupancy inputs.It is also frequently deployed in agricultural processing equipment,such as grain dryers or milking systems,where environmental conditions are harsh but control logic remains straightforward.Additionally,the IC670CHS101 serves as a modernization path for aging relay-based panels in legacy plants,offering programmable logic with diagnostic visibility while retaining existing field devices.Its simplicity,reliability,and low total cost of ownership make it a persistent choice across light industrial and infrastructure applications.

Installation and Maintenance

Pre-installation preparation:Before installing the IC670CHS101,ensure the DIN rail is straight,securely fastened,and free of paint or corrosion that could compromise grounding.Allow at least 50 mm of clearance above and below the module for ventilation and access.Confirm that the selected power source matches the requirements of the IC670PWR101(if used)and that the total current demand of all attached modules does not exceed the supply capacity.Always de-energize the panel during installation to prevent electrostatic discharge damage.

Maintenance recommendations:The IC670CHS101 itself requires no active maintenance,but periodic visual inspections are recommended in dusty or humid environments.Check for loose terminal screws,signs of overheating near power connections,or physical damage to the latch mechanism.When replacing modules,verify that they click firmly into place—partial insertion is a common cause of communication loss.Maintain updated program backups using Logicmaster 90 or compatible tools to enable rapid recovery.Store spare IC670CHS101 units in anti-static bags in a climate-controlled environment to preserve connector plating and mechanical integrity.
