GE IC693350-CG Single-slot CPU Module (Series 90-30)

Description

What This Product Solves

In demanding industrial automation and process-control applications, one of the key challenges is ensuring that the central controller can handle both logic execution and I/O throughput while supporting networked communications, without becoming a bottleneck. The GE IC693350-CG addresses this challenge by providing a powerful CPU module for the Series 90‑30 platform, designed to deliver robust performance, reliable logic execution and flexible communication support for I/O-dense and networked systems. When projects demand both legacy I/O integration and modern connectivity (Ethernet, fieldbus, distributed I/O), a CPU that simply cannot keep up may limit system stability, increase engineering overhead or compromise signal reliability. The IC693350-CG solves this by combining a 25 MHz 80386EX core, deterministic scan rates and support for advanced communications—all in the familiar Series 90-30 architecture. In environments where modular integration is key, where “system uptime” is non-negotiable, and where the engineering team needs predictable performance for logic, motion, and networked data exchange, the GE IC693350-CG brings high-reliability automation into reach. It supports the transition from discrete I/O islands to distributed, Ethernet-enabled architectures while retaining the modular I/O, I/O signal consistency and long-life support expected in industrial automation.

How the Product Works & Fits into a System

The GE IC693350-CG serves as the CPU module in a Series 90-30 rack system. It plugs into the backplane of the controller’s base plate and coordinates logic execution, I/O scanning, communication tasks, and system supervision. From a system architecture viewpoint, the module sits at the core of the automation stack: field I/O modules gather analog and digital signals, the backplane transports them to the CPU, the IC693350-CG processes the logic (programmed via legacy tools like VersaPro or LogicMaster), and optionally communicates with upstream systems via serial, Ethernet or fieldbus networks. The module supports up to eight baseplates (the CPU baseplate plus seven expansion or remote racks), giving flexibility in building distributed I/O architectures. Networked communication is enabled via option modules (e.g., Ethernet, Profibus) which interface with the CPU’s firmware and backplane—so the IC693350-CG becomes the logical hub that ties I/O signal flow into system-wide control. Diagnostics and status monitoring help maintain high reliability: fault detection in logic scan, I/O channel errors, and communication health all feed into the CPU’s status registers. In short, the IC693350-CG integrates seamlessly into modular I/O architectures, making it ideal for upgrades, retrofits or new installations where system stability, signal reliability, and modular integration matter.

Technical Highlights Summary

Real-World Benefits

Using the GE IC693350-CG means you’re choosing a CPU engineered for long-term performance and modular integration in industrial environments. Because it’s based on a 25 MHz 80386EX core and offers a typical scan rate of ~0.22 ms per 1K of logic, it ensures your logic and I/O signal processing remain stable, even as system demands grow. This translates into fewer surprises during commissioning, reduced tuning time, and better confidence in system response when mixing analog and digital inputs, networked nodes, and high-performance modules. The modular nature of the IC693350-CG reduces engineering overhead: you remain within the Series 90-30 ecosystem, so spare parts, software tools and maintenance workflows stay consistent — lowering lifecycle cost and training burden. Additionally, because the module supports communication options and distributed I/O architectures, it ensures that you’re not locked into isolated islands of control. The redundancy and diagnostics built into the architecture (monitoring of I/O channels, communication status, and internal timing) help reduce downtime and simplify maintenance. In short, the IC693350-CG ensures your control platform remains capable, reliable and future-proof, supporting your automation goals with high reliability and signal integrity.

Typical Use Cases

The GE IC693350-CG is well-suited for applications requiring a robust central controller in environments with mixed legacy and modern requirements. In water/wastewater or utilities, it can handle distributed I/O racks, monitor analog levels, control pumps and coordinate supervisory systems via Ethernet — ensuring critical system uptime. In manufacturing automation, it oversees packaging lines, indexing conveyors and mixed digital/analog signals, while providing communication to higher-level MES/HMI networks — bridging process control and discrete automation. In oil & gas or chemical plants, it integrates with fieldbus networks, handles I/O signal integrity in harsh environments, and supports modular expansion for future growth. Wherever engineers need a single-slot CPU module that supports modular I/O, network communications, and reliable logic execution in an industrial automation context, the IC693350-CG delivers a proven solution.

Setup Notes & Maintenance Insights

Before installation of the GE IC693350-CG, confirm your Series 90-30 rack supports the CPU slot and that the firmware version is compatible with your programming tools (LogicMaster, VersaPro, Proficy Machine Edition). Ensure proper power supply (+5 V) and cooling within the enclosure. When wiring I/O modules and configuring communication options, verify that any Ethernet or fieldbus modules match the firmware revision listed for the CPU (for example, firmware version 10.00 or later may be required for certain functions). During commissioning, review the CPU’s LED indicators and status registers to confirm normal operation and communication. For ongoing maintenance: periodically back up the user program and firmware, monitor status registers for fault conditions (%S files), inspect connectors and cables for signs of wear or corrosion, and ensure the module firmware remains current. Because this module is often used in legacy applications, maintain a documented revision level (-CG), firmware version, and spare part history to streamline future replacement. A well-maintained system with the IC693350-CG will reduce unplanned downtime and simplify troubleshooting when issues arise.
