GE IC693CPU350-CG CPU card

The GE Fanuc IC693CPU350-CG serves as the primary IC693CPU350 CPU Module utilized to execute logic scanning and system I/O processing across Series 90-30 platforms.

Hardware Specifications

Backplane Bus Communication Velocity and Firmware Compatibility

Operating with an Intel 80386EX 25 MHz microprocessor, the IC693CPU350-CG executes direct backplane bus communication velocity routines to maintain deterministic scan cycles across local and expansion racks. Internal memory registers ensure firmware flash compatibility across connected Series 90-30 expansion cards, enabling online logic updates and non-volatile system state preservation without inducing backplane bus latency.

Frequently Asked Questions

Q: What is the current draw from the backplane supply rail for the IC693CPU350-CG?

A: The module requires 670 mA at 5 VDC directly from the baseplate rack power supply. System power load calculations must include this draw, and hot-swapping is prohibited—main power must be isolated prior to insertion or removal.

Q: Does the CPU support floating-point math routines in user logic?

A: Yes, the IC693CPU350-CG fully supports floating-point math instructions for complex process control calculations.

Field Installation Guidelines

1. Power Disconnection: Fully isolate incoming main power to the baseplate rack and attached expansion baseplates prior to mounting the CPU module.
2. Rack Insertion: Place the IC693CPU350-CG into Slot 1 of the Series 90-30 baseplate. Push the module until the top and bottom frame clips snap into place.
3. Serial Cable Grounding: Route serial communication cables away from high-voltage AC conductors and terminate shield wires to functional earth (FE) to preserve signal integrity against electromagnetic interference.
