Description
GE IC693CPU374-JY Core Processor Module – Ethernet-enabled CPU for Series 90-30 Control Systems
The GE IC693CPU374-JY is a high-performance CPU for the Series 90-30 PLC platform, built for plants that need dependable PLC logic with built‑in Ethernet. From my experience, this model hits a sweet spot: it’s fast enough for most packaging lines, water treatment skids, and discrete assembly cells, while staying fully compatible with existing 90‑30 racks and I/O. The “-JY” suffix typically denotes a later factory revision; functionally it behaves like the IC693CPU374 in most cases, which is why maintenance teams like it as a drop‑in replacement.
You might notice that the embedded 10/100 Ethernet port makes networking and HMI integration straightforward, and the two serial ports keep legacy devices in play. A maintenance manager at a beverage plant told me their changeover time dropped noticeably after moving to CPU374 because they could diagnose via Ethernet instead of walking the line with a serial cable.

Application Fields
The IC693CPU374-JY typically fits mid‑range machines and processes that value proven 90‑30 reliability with easy Ethernet integration:
- Packaging and material handling lines needing fast recipe changes and Ethernet HMIs
- Water/wastewater skids where plant SCADA polls data via SRTP or Modbus TCP
- Automotive sub‑assemblies that retain serial devices alongside new Ethernet panels
- Food & beverage batching with mixed analog/digital I/O and event logging
- General factory automation upgrades where a drop‑in 90‑30 CPU minimizes downtime
Advantages & Value
- Reliability: Series 90‑30 hardware is known for long life. This CPU seems to be one of the easier units to keep in service due to broad field familiarity.
- Compatibility: Works with existing 90‑30 racks, PSUs, and I/O—no re‑wiring overhaul.
- Lifecycle cost control: Ethernet built‑in often eliminates the need for a separate comms module and cabling.
- Supportability: Program and troubleshoot through Proficy, with quick remote access over the plant network.
- Risk reduction: A straightforward replacement path for legacy CPUs; less risk of software revalidation compared to a platform change.
Installation & Maintenance
- Cabinet & environment: Mount the 90‑30 rack in a ventilated, clean enclosure (NEMA/IP rated as required). Keep within 0–60 °C and non‑condensing humidity.
- Power & grounding: Size the 5 VDC backplane capacity with margin; bond the panel ground properly and use shielded Ethernet/serial cabling where noise is present.
- Wiring practices: Separate high‑voltage and control wiring; provide strain relief for the Ethernet patch cord; label serial ports for device mapping.
- Safety: De‑energize before insertion/removal; observe ESD precautions when handling the module.
- Routine maintenance: Backup the project file after any change, verify battery status during PMs, and update firmware carefully (via Ethernet or serial) when required by a fix or feature.
- Spare strategy: Keep one like‑for‑like CPU on the shelf; verify firmware alignment with your validated program to speed swap‑outs.
Quality & Certifications
