GE IC693CPU331-CE Series 90-30 PLC CPU Module
Configured for high-speed logic execution and central I/O management in Series 90-30 automation platforms, the GE IC693CPU331-CE (IC693CPU331 CPU Module) provides direct physical/electrical execution. Operating as a single-slot central processing unit driven by an embedded 10 MHz 80188 microprocessor, this module handles up to 512 discrete inputs, 512 discrete outputs, 128 analog input words, and 64 analog output words. It mounts exclusively into Slot 1 of the primary baseplate, coordinating system logic over the backplane bus while drawing power directly from the backplane supply.

Deterministic Backplane & Serial Communication
The IC693CPU331-CE processor establishes fixed-latency data exchange across the internal Series 90-30 backplane bus, driving systematic logic updates at a base rate of 0.4 ms per 1K of Boolean instructions. Backplane bus communication velocity and power management are tightly regulated, requiring a stable supply current of 350 mA at 5 VDC. The single-slot architecture interfaces directly with the power supply module's serial port connector to run SNP (Series Ninety Protocol) and SNP-X slave protocols for programming, diagnostics, and human-machine interface (HMI) integration. Firmware flash compatibility and memory retention are preserved via an integrated battery-backed real-time clock, maintaining register status and program pointers through complete power interruption cycles across the entire 5-baseplate local rack topology.
Frequently Asked Questions
Q: Does the IC693CPU331-CE support hardware interrupts for high-speed event processing?
A: No, the Intel 80188 hardware architecture on this specific CPU model does not support external hardware or time-based interrupts. All process inputs and control logic evaluate strictly within the cyclic backplane scan routine.
Q: Which baseplate slot must house the IC693CPU331-CE CPU module?
A: The IC693CPU331-CE must install directly into Slot 1 of the primary Series 90-30 baseplate. Installing the module into expansion slots or non-CPU baseplates prevents system backplane initialization.
Field Installation Guidelines
- Power Off Before Module Insertion: Ensure all AC and DC incoming power to the rack power supply is completely disconnected prior to installing or removing the CPU module from Slot 1 to prevent backplane bus transients.
- Grounding & Shielding Protocol: Verify that the baseplate DIN-rail or panel-mounting surface is grounded to earth via a low-impedance copper bus bar. All serial communications wiring connected to the power supply interface port must utilize twisted-shielded pair conductors grounded at one terminal end only.
- Power Budget Calculation: Before energizing, verify that the total 5 VDC current load of all I/O modules, option cards, and the 350 mA CPU consumption does not exceed the maximum output rating of the Series 90-30 power supply.
