Description
1. At-A-Glance Executive Brief
- Model: IC693CPU374-HX
- Brand: GE Fanuc / Emerson Automation (Series 90-30)
- Part Type: Single-Slot CPU Processor Module
- Lifecycle Status: Mature / Legacy Support Tier
- System Compatibility: GE Fanuc Series 90-30 PLC Architecture
- Core Protocol: Embedded 10/100 Mbps Ethernet & EGD
2. Technical Introduction
- Problem: Sudden processor faults or communication lockups on legacy GE Series 90-30 controller racks leave maintenance teams unable to execute logic scans or interface with plant supervisory networks.
- Agitation: Waiting on lengthy OEM component backlogs or risking unverified marketplace brokers can prolong facility outages and lead to severe financial losses during operational downtime.
- Solution: The GE Fanuc IC693CPU374-HX drops directly into the primary baseplate slot, delivering a 133 MHz processing speed and built-in dual Ethernet connectivity to restore control loop execution immediately.

4. Field Engineer’s Tech Notes
- Power Supply Capacity Check: The IC693CPU374-HX draws 7.4 Watts from the 5 VDC backplane rail, which is higher than older Series 90-30 processors. Ensure your baseplate uses a high-capacity power supply module (such as the IC693PWR330) to prevent low-voltage dropouts during initialization.
- IP Address and Firmware Configuration: When replacing a failed CPU, verify that the hardware firmware version and network IP configuration match your backup project file in Proficy Machine Edition. Mismatched network parameters will prevent SRTP communication handshakes and isolate the rack from supervisory SCADA nodes.
5. Adaptive QA & Testing Protocol
Incoming IC693CPU374-HX modules undergo bench validation on an active Series 90-30 test chassis. Technicians verify internal DC power regulation draw, test dual Ethernet port communication speeds, validate memory battery backup retention, and execute compiled logic execution sweeps. Complete test validation reports and diagnostic check logs are available upon request prior to dispatch.
6. Buyer’s FAQ
- What warranty coverage applies to this CPU module?All units—supplied as New Surplus (NSFP) or professionally refurbished—include a full 12-month operational warranty from the invoice date.
- How fast can this part be delivered to my facility?In-stock items ship same-day via priority international air courier to minimize active plant downtime during critical process upsets.
- Does this processor include built-in serial ports?No. The IC693CPU374-HX relies entirely on its dual Ethernet ports for high-speed connectivity; serial programming and SNP/SNPX protocols are routed through the RS-485 port on the baseplate power supply module.
