Distributed I/O Solution – GE IC693CHS393 | Series 90-30 Remote Expansion Chassis
Where This Product Is Used
The GE IC693CHS393 is a 9-slot remote expansion chassis designed for the GE Series 90-30 PLC platform. It is deployed wherever engineers need to extend I/O capacity beyond the local rack — placing field-level I/O modules physically close to the process equipment while maintaining centralized CPU control. Typical deployment environments include:
- Discrete Manufacturing Lines — Automotive assembly, packaging machinery, and conveyor systems where I/O points are spread across a large floor area.
- Oil & Gas Facilities — Wellhead control panels, pipeline monitoring stations, and compressor skids requiring remote I/O in hazardous or remote locations.
- Water & Wastewater Treatment Plants — Pump stations, lift stations, and filtration systems distributed across large plant footprints.
- Power Generation & Utilities — Substation automation and generator control where I/O must be located near switchgear.
- Food & Beverage Processing — Filling lines, CIP systems, and batch reactors with distributed sensor/actuator networks.
- Building Automation & HVAC — Large commercial facilities using Series 90-30 for centralized BMS with remote zone control.

Why Engineers Specify This Model
- Proven Platform Longevity: The Series 90-30 has been in continuous production since the early 1990s. The IC693CHS393 is a mature, field-proven chassis with an extensive installed base and well-documented behavior.
- 9-Slot Capacity: Provides maximum I/O density in a single remote chassis — accommodating up to 9 mixed I/O or specialty modules without requiring an additional expansion chassis.
- Reduced Field Wiring Cost: Placing the chassis near field devices eliminates long cable runs from sensors and actuators back to a central panel, significantly reducing installation labor and material costs.
- Flexible Topology: Multiple IC693CHS393 chassis can be daisy-chained from a single CPU rack, enabling scalable distributed architectures without additional communication processors.
- Broad Module Compatibility: Accepts the full range of Series 90-30 discrete, analog, specialty, and communications modules — no module restrictions in remote slots.
- Simplified Spare Parts Management: A single chassis model covers all remote expansion needs in the Series 90-30 family, reducing spare parts inventory complexity.

Application-Specific FAQ
Q: Can the IC693CHS393 be used as the main (local) CPU chassis?
A: No. The IC693CHS393 is a remote expansion chassis only. It does not accept a CPU module. The CPU must reside in a local base chassis (IC693CHS391 or IC693CHS392).
Q: How many IC693CHS393 chassis can I connect to one CPU?
A: The Series 90-30 supports up to 7 expansion racks (local + remote) per CPU, depending on the CPU model. Consult the GE Series 90-30 Hardware Reference Manual (GFK-0356) for your specific CPU’s expansion limits.
Q: What is the maximum cable distance between the CPU rack and a remote IC693CHS393?
A: Using IC693CBL302 (7.6 m) cables in series, the maximum total bus expansion distance is approximately 15 meters. For longer distances, a Bus Transmitter Module (IC693BEM320) is required.
Q: Does the IC693CHS393 require its own power supply?
A: Yes. Each remote chassis requires a dedicated Series 90-30 power supply module installed in its leftmost slot. The CPU rack power supply does not power remote chassis.
Q: Is the IC693CHS393 compatible with the Series 90-70 or VersaMax platforms?
A: No. The IC693CHS393 is exclusively compatible with the Series 90-30 platform. Series 90-70 uses IC697 chassis; VersaMax uses its own modular I/O system.
