Why Engineers Specify This Model
- Proven Field Reliability — The IC693CPU350 has accumulated decades of runtime in harsh industrial environments, with a well-documented MTBF record that satisfies plant reliability engineers.
- Cost-Effective Mid-Range Performance — Positioned between entry-level CPUs (IC693CPU311/321) and high-end models (IC693CPU374), it delivers sufficient scan-time performance for the majority of mid-complexity control programs without over-specifying hardware.
- Broad I/O Ecosystem — Compatible with the full Series 90-30 I/O module library: discrete, analog, specialty (motion, communications), and intelligent option modules.
- Simplified Spare-Parts Strategy — A single CPU model can serve as a hot spare across multiple machines on the same platform, reducing warehouse SKU count.
- Long Installed Base — Millions of units in service globally ensure continued availability of trained technicians, legacy documentation, and compatible replacement parts.

Application-Specific FAQ
Q: Is the IC693CPU350 still manufactured by GE?
A: GE Fanuc’s PLC division was transitioned to Emerson (now Movicon / Proficy brand). The IC693CPU350 is a mature product; new production has ceased, but high-quality surplus and refurbished stock remains available through authorized distributors like Konmask.
Q: Can the IC693CPU350 communicate over Ethernet natively?
A: No. The CPU350 has a single RS-232 serial port. Ethernet connectivity requires adding an IC693CMM321 or IC693CMM311 communications module to the rack.
Q: What is the maximum program size supported?
A: 32 KB of combined program and data memory. For larger programs, consider upgrading to the IC693CPU360 (64 KB) or IC693CPU374 (240 KB + Ethernet).
Q: Is this module compatible with VersaMax I/O expansion?
A: The IC693CPU350 supports local and remote Series 90-30 I/O expansion via the Genius Bus or Remote I/O Scanner modules. VersaMax I/O requires a separate VersaMax CPU or a bus controller module.
Q: What programming software is required?
A: GE Proficy Machine Edition (Logic Developer – PLC) is the current supported programming environment. Legacy Logicmaster 90-30 software can also be used for older program formats.
Q: Can Konmask provide a Certificate of Conformance?
A: Yes. A Konmask Certificate of Conformance (CoC) is available upon request at time of order. Third-party inspection reports can be arranged for large-volume orders.
