Description
Overview
The IC693CPU351 processor module is part of the GE FANUC Series 90‑30 control platform, designed to provide reliable execution performance for mid‑ to large‑scale automation systems. This modular CPU integrates expanded memory resources, multiple communication interfaces, and broad I/O support, making it suitable for demanding industrial control tasks.
Architecture and Processing
At the core of the IC693CPU351 is an Intel 80386EX processor operating at 25 MHz. Its architecture supports efficient execution of ladder logic, structured block programming, and data‑intensive routines. The module includes 240 KB of user‑available memory, offering significantly more storage capacity than earlier Series 90‑30 CPUs.
The CPU supports over 2000 timers and counters, enabling precise sequencing and time‑critical operations across distributed control environments.
Communication and I/O Capacity
Three onboard serial ports provide flexible connectivity for programming devices, operator interfaces, and external communication modules. The CPU supports large I/O systems, accommodating up to 2048 discrete points and more than 32,000 analog channels when used with appropriate expansion modules.
The module operates from a 5 VDC supply at approximately 890 mA, maintaining compatibility with existing Series 90‑30 power supplies and racks.
Installation and Grounding
For stable operation in electrically noisy environments, GE specifies proper grounding using either the included green grounding wire (44A735970‑001R01) or an optional grounding bracket (44C715646‑001R01). Correct grounding improves noise immunity and ensures consistent communication performance.
