GEIC630CPU301ASeries Three CPU / Programmer Unit — 4K Words CMOS RAM, 400 I/O Points, Built-In Ladder Programmer and Diagnostics

Product Description

What this part is:

The GE Fanuc IC630CPU301A is the CPU and built-in programmer unit for a GE Fanuc Series Three programmable controller. It contains the microprocessor that executes the ladder logic, scans the I/O and holds the user program. The same unit carries a keypad and display for entering and editing programs, adjusting timer and counter presets, monitoring coil and contact status, starting and stopping the program, and reading out error codes and diagnostic reports. Unit Quantity: 1 Pc. Manufacturer Status: Discontinued, no factory replacement.

Decoding the designation:

IC630 — GE Fanuc Series Three product line, separate from IC610 Series One, IC600 Series Six and IC693 Series 90-30.

CPU — central processing unit; on this platform the CPU and programmer are the same module.

301 — the 4K-word CPU / programmer unit.

A — hardware revision letter. Revision B (IC630CPU301B) is the other commonly traded revision; revisions in this family are functionally equivalent.
